(Cl. 2--181)
The present invention relates to sweat bands
for hats, particularly sweat bands made of fabric
rather than leather, and vto a novel method of
producing the same.
This invention, of a radically new type of sweat
construction to provide the elasticity necessary
for processing and for flanging and stretching,
although it is not intended to limit the invention
band, has for its main object the creation of a
sweat band which will combine the feature of an
unusually accurate head and hat size, and in
some embodiments with a new material specially
economic, technical, and fashion characteris
tics to the style, weight, and quality of hat in
which the sweat band is to be used.
10 developed for the technical requirements imposed
by the new sweat band.
In the present state of the art, the size of the
hat is closely approximated by the size of the
block used in shaping the hat body, a suitable al
15 lowance being made for the space to be occu
pied by the sweat band. The size is then fixed
by the sweat band itself, which is usually a strip
of leather, cut to specified length and then sewed
in the curved shape or “scope” appropriate to
'20 the hat, in which it is affixed, as by sewing.
is obvious that the dimensio-nal precision of this
method is limited by the errors inherent in the
process and that there are corresponding varia
tions from standard hat size. Slight errors at
25 the time of cutting or when sewing the ends of
the strip make a considerable diiference in the
feel and fit of the hat upon the head of a user,
and often result in the fit and non-fit of hats
even though they are supposedly the same size.
This invention first improves on the conven
tional sweat band by forming it, in effect molding
it, in a continuous oval ring, using accurately
machined forming dies.
It is equally obvious that in some forms of the
35 present invention the materials in current use
for sweat bands are not suited to such a‘fo-rming
process and in fact would utterly fail if so proc
to any kind or class of fabric, the process per
mitting the selection of one suited in all essential U1
It will be noted that the use of one or more fab
rics in combination with a modern thermo-plas
tic coating and cement, as provided by the pres
ent invention, also secures a leather-like con
sistency, a more or less absorbent surface neXt
to the wearer’s head and a dam-like backing
which is unusually inert to perspiration, water, 15
oil, mild alkalis, and acids.
In certain applications of this invention a further advantage accrues in that the same coating
may be used to secure the sweat band to the felt,
thus doing away with sewing, with its attendant 20
risk of the thread acting as aV wick to carry per
spiration through the felt.
'I‘he use of a cloth sweat band for hats has been
limited heretofore because it tended to wrinkle,
and more particularly because it permitted the
passage of sweat very quickly to the hat body and
hat band, thereby marring the appearance of the
hat, unless careful arrangement was made to back
the cloth with a darn. It is an object of the pres
ent invention to provide a cloth sweat band for
hats which will not wrinkle, and which will be
highly impervious to the passage of sweat, mois
ture, and dust.
This desirable object is accomplished through
the provision of a plastic surface impregnation or 35
coating on the hat band which renders it water
proof. In its present preferred form this plastic
essed. Therefore, the second step in my invention
is in the form of a phenol-formaldehyde or glyc
is the creation of a material which is at once
erol phthalic anhydride condensation product,
and other of the preferably thermally responsive 40
40 adapted to accurate forming and also possessing
the qualities of soft flexibility, reasonable 4surface
absorption of perspiration in combination with
resistance to passage of perspiration to the hat,
comfortable feel, fashionable appearance and like
45 characteristics essential to its advantageous use
in sweat bands.
Some of these desirable characteristics are ac
complishedV according to this invention by a
combination of fabric with a modern »thermo
50 plastic cement and coating, such as is made of
bakelite resins or of glyptal, which are plastic
only at temperatures well >above those to which
hat sweat bands are subjected in normal use.
The fabric may be woven under loose tension,
55 but is preferably of a tubular knit vor a braided
According to present methods of manufacture
there is sometimes considerable disparity in the
sizes of hat sweat bands even though they are
supposed to be of a standardized size. For exam
ple, a man may go- into a store and ask for a 71A;
hat which should ñt him very well, and find the
hat either too small or too large, dependent upon
lack of control in the manufacturing process.
It is an important object of the present inven
tion to make a fabric sweat band for hats which
will be self supporting; viz., remain in an upright
inverted position within the hat, even though the
upper end thereof within the hat is free to ac
commodate a crown lining. And, a complemen
tary object is to have the self-supporting fabric
band so that it will not allow perspiration to pass
through the sweat band to the hat.
It is an object of the present invention to ob
DI viate this common error or weakness in hat con
struction and to provide sweat bands which will
be made positively uniform to the various sizes.
In meeting this object, the present invention
provides a process of stretching and setting cloth
hat bands to fixed and standardized sizes so that
there can be no disparity in the individual runs
thereof. In effect, this is accomplished, accord
ing to the present processes, by molding the hat
sweat band to the desired size.
It is an important object of the present inven
tion to provide a cloth sweat band which will be
fully waterproof and thereby prevent moisture
and sweat from seeping through.
According to the present invention this is ac
20 complished by impregnating or saturating the
cloth sweat band with a thermo-plastic, by a
suitable surface coating of the thermo-plastic on
one or both sides of the fabric, by impregnating
or saturating an amount insufficient to render
25 the same waterproof and a suitable coating ap
plied to one or both surfaces of the fabric in order
to obtain a waterproof or impervious structure,
or by a coating or impregnating of thermo
plastic on the cloth band together with a back
30 ing strip of rubberized silk or similar waterproof
It is sometimes desirable to provide a hat with
a sweat band having the characteristic of ab
sorbing sweat, but of not allowing the sweat to
pass to the hat.
This is advantageously accomplished by the
present invention through the provision of a
sweat band having a cloth or fabric head con
tacting section with a dam-like backing of
40 thermo-plastic adapted to prevent sweat from
seeping fully through the cloth sweat band.
It is an important object of the present in
vention to provide a sweat band dispensing with
the usual joint entirely in order to obviate the
45 errors of manufacture when an operator must
cut to length, join and sew a band, and to allow
placing the sweat band in the hat without con
cern relative to the location of the joint.
In meeting this object, the present invention
50 provides a sweat band made of a continuous an
nular ring of fabric. in its preferred form this
ring is initially yielding in diameter, and ac
cording to the process of the present invention
is stretched and set to the wearing size. The
55 sweat band in its preferred form is flexible so
that it may follow irregularities on the head of

The present invention is not limited to the de
tails of construction and arrangement of parts
illustrated and described herein, for the inven
tion is capable of other embodiments in whole or
part, and the phraseology used is for the purpose
of description and not of limitation.
Referring now in detail to the drawings which
illustrate the present preferred embodiments of
the invention, it should be noted that in general
two methods and forms of structure are provided,
viz.: impervious in one form as by impregnating
the band or by surface treating the inner face
thereof, whereby a leather like feel is imparted to
the fabric band, and semi-pervious in the other
form as by surface treating the back of the band
or by otherwise providing a dam like backing so
that the fabric band has a soft silky feel and
somewhat absorbent characteristics.
The sweat band 20A, shown in Fig. 6, prefer
ably comprises a base member 2D in the form of a
unitary or seamless rough fabric band of tubular
shape, as shown in Fig. 2, so made either by felt
ing, weaving, or knitting. Preferably, it is made
from cellulose acetate, or other synthetic yarn,

for the single ply sweat band.

Fig. 3A shows the rough fabric band in flat disk
so that it can be rendered plastic or semi-plastic 55
when subjected to heat and pressure. It is pre
ferred that the band be continuous in order that
lapping and securing ends of a strip may be ob
viated. The band 20 may be woven to short
lengths, or may be of a long tubular shape and 60
cut to individual short lengths. Also, the band
is preferably knit so that the weft threads yield
readily in order to stretch to various diameters.
Preferably the warp threads do not yield, in order
to maintain the length of tube or width of strip 65
properly while forming the band to various diam
If preferred, the rough fabric band may be in
the form of a continuous ñat annular disk 2Gb as
shown in Fig. 3A, of pressed, knit, or woven ma 70
terial. However, since less stretching is required,
the particular wearer but the circumferential
length of the band is fixed and invariable be

a sleeve-like band such as shown in Fig. 2 is pre
While the band of fibrous material may be
knitted, Woven, or felted to the desired final size, 75
it is clear that such a procedure would render it
necessary to have base bands for each hat size
made. It is preferred from a manufacturing
standpoint to form the band to a rough size
smaller than the smallest head size, and to stretch
the base band to a given head size in a suitable
die or mold. - In this way several head sizes may
be made from a given size of rough band, reducing
the number of sizes of rough bands necessary.
10 Also, >by stretching and setting a small band to a
given larger size, the normal circumferential yield
of the initially formed fabric may be taken up
so that the ñnal and formed sweat band maintains
the desired size.
Accordingly, in its rough or preliminary state,
shown in Fig. 2, the band is preferably smaller
than the fabricated size, so that it must be
stretched and can be made to take a dei-‘mite set.
In one form the rough band 20 is formed without
20 impregnation or surface treatment. For example,
when the band is made» of cellulose acetate, or
the like, the individual ñbres thereof are capable
of elongation so that they may be stretched and
set. Also, rbecause such bands and the fibres
25 thereof contain a certain amount of water or
moisture, they are rendered plastic or semi-plastic,
especially when subjected to heat and pressure
to the desired degree. Such band is placed in a
suitable forming apparatus (e. g., apparatus 2|
30 shown in Fig. l) to be stretched and set (and
preferably dried somewhat in the forming ap
paratus) to a predetermined shape and size,
whereupon it is ready for' use in hats. This
stretched and set fabric band may alone be se
35 cured within a hat in any of the now well known
ways, or it` may be provided with a strip of `mois
ture impervious'backing and then secured to the
Preferably this forming is done by both stretch
40 ing and pressing so that the individual fibres 22
in the fabric will, while in plastic state, be pressed
together to set and lock together and thereby
better maintain the fabricated size. The form
ing is also preferably done with heat to liberate
45 the moisture in the ñbres of the fabric and there
by render the fibres plastic or semi-plastic, and
by evaporating the moisture render the fabric
less capable of elongation after the band is formed.
i The heating also effects a better bonding or set
between the individual fibres at the points where
they are pressed together.
By stretching the band 28A and setting the
fibres 22, a greater rigidity is imparted to the
band s-o that it will ‘be self supporting within the
hat and have a neat finished appearance at all
times, rather than soft to the possible extent of
loosely falling down from, or out of, the hat of its
own weight. Also, sufficient rigidity is imparted
60 thereto to prevent the band from pulling out of the
inside of the crown when a user removes the hat
from his head.
One type of apparatus to so form the sweat band
is illustrated in Fig. l, although it will be under
stood that other forms of apparatus may also be
used. This apparatus includes an expansible
member 23 and a‘sizing member 24 mounted for
relative movement, as by pillar posts 25 and mov
ing mechanism 26 in any suitable press 2l.- The
70 members 23 and 24 are preferably each provided
with chambers 28 and 29 respectively connected
to a two-way inlet valve 3l! and two inlet lines 3|
and 32, and also to an outlet line 33 and valve 34.
The expansible member 23 is held in a retracted
75 or small condition by a spring 35, while the studs
36 engaging a rib 31 tends to centralize it relative
to the sizing member 24.
An operator merely places the rough band 2|]
upon the expansible member 23 and then spreads
a lower section thereof to a ring 38 when a ñange
39 is to be formed. This ñange 39 may be of a
smaller size or may be omitted entirely as shown
by dot and dash lines 39’ if preferred. After
the rough band is properly located on the ex
panding member 23, the sizing member 24 is 10
moved to the lowered position. Thereafter, the
outlet valve 34 is closed and the inlet valve 30 is
connected to the steam- or hot water line 32 in
order to fill the chambers 23 and 29 and concur
rently expand the member 23 as pressure builds 15
up in the latter to move the parts 23a and 23h
away from each other against the tension of the
spring 35.
Any desired degree of heat and pressure may be
introduced, dependent upon the materials used, 20
the degree of inherent or applied moisture impregnation in the fabric, and the final result de
A recessed section 24’ and a smaller
diameter 4U adapted to engage with the upper
section of the member 23 may also be used to 25
limit the extent the fibres 22 are pressed into
each other, thereby insuring a uniform result.
The fixed size of the member 24 absolutely in
sures a uniform` diameter of the formed band
The forming apparatus may be shaped to give
any desired contour and size to the sweat band.
Fig. 5 illustrates how one band may be stretched
and set to various larger sizes.
It will be apparent from the foregoing that the 35
present invention provides a novel sweat band
28A made from a one piece fabric in tubular
form stretched and set to a predetermined size,
yet flexible or pliable to- conform with the shape
of the head, but comparatively unelastic in its
diameter, and provides a novel method of pro
ducing the same in a uniform and economical
By superposing two rough bands 2t, similar to
the rough band shown in Fig, 2, it is possible to
form the two ply sweat band 25B shown in Fig. 9.
This is accomplished by placing one band 2G with- `
in another and then following the same steps
outlined relative to the one ply band 20A. A
two ply band of this type ñnds favor where it 50
is desired to have a hat band more rigid than
the single ply band 29A, of Fig. 6. If preferred,
this two ply band may be secured together at the
edges 4I by a line of stitching 43. However, this
is not necessary since the fibres 22 of the one 55
band may be pressed into and set relative to the
fibres in the other band sufñciently to maintain
the bands in superposed relation. The burnish
ing or the stitching may be used for ornamenta
tion or to impart a more finished appearance to 60
the edge of the band.
A band 20C may also be similarly formed from
a long strip of fabric 20', made of cellule-se ace
tate or other fabric, by connecting the ends the-re
of'by a joint 4.4, secured by any suitable adhesive 65
or by stitching 45. Preferably, this is also made
in the form of a rough band of smaller diameter
than any fabricated size. In forming it into a
sweat band the previously outlined steps for the
band 2BA are followed.
’I'he sweat bands just described have the ad
vantage of economy, and although they have a
smooth feel and smooth fit on the head, which is 75
very desirable, they are not fully impervious to
perspiration. Accordingly, an improved or pref
erable form of the present invention consists of
forming a sweat band 20D (like the band 2BA,
impregnated as described hereinafter) by treat
ing the rough band 2S with a plastic 45’. This
plastic is preferably any of the well known syn
resin or the like used in the present invention,
does not deteriorate quickly and is not affected
by mild chemicals and body acids.
t is thor
oughly waterproof and while it is suitably flexible
or pliable to permit the band to conform to slight
differences in head shapes, it effectively prevents
thetic resins such as phenol formaldehyde con
ing to a larger size. It also has the advantage of
maintaining the fabric in an upright and smooth
condition within the hat, at all times.
When the plastic has been cured and set in
the fabric, it in effect changes the fabric from
a yielding band to a non-yielding band, for it
binds the individual ñbres, one to the other,
wherever they engage, and in effect forms a long
densation products or bakelite, the glycerol
10 phthalic anhydride or glyptal resins, urea-form
amine - formaldehyde,
vinyl resins.
This treatment may be accomplished by a com
plete immersion, spraying, brushing, or the like
of the fabric band with the plastic in liquid, pow
elongation and prevents the band from stretch
der or paste form, in order to effect a substan
strip of set plastic incapable of elongation, yet
tially complete impregnation between the fibres
of the fabric. If the plastic contains evaporat
flexible enough to conform with round, oval, and
other shaped heads.
When the fabric band 2U is so prepared, with
ing agents it may be applied to the band 20A
after the hereinbefore mentioned process of
forming, to make the band 29D, and to thereby
render the band more self supporting, prevent
stretching, and make it impervious to perspira
tion. However, the plastics are preferably ther
25 mally responsive and are applied previously to
the forming.
After treatment with plastic 45', the rough
band 20 is placed in the forming apparatus 2l
to be stretched, formed, and set to the desired
30 shape and size to form band 29D with a plastic
45’ in the same manner as the band 2BA.
stretched and impregnated band is subjected to
heat and pressure to convert the impregnant to
its hard and infusible “A” stage, or to a some
35 what fusible “B” stage, the latter being such that
it will be affected only by temperatures well above
those of a body and above those experienced
within a hat.
Heat and pressure of desired degree may be
admitted through the line 32 and valve 30 while
the valve 34 is closed to effect the proper form and
'cure of the plastic associated with the cloth band.
Temperatures above 180° have been found most
satisfactory with the hereinbefore mentioned
45 thermo-plastics. When this has been effected the
valve 34 may be slightly opened, the steam line
32 closed, and the line 3i of cold water, refriger
ant, or the like opened to cool the band and there
by more quickly set the plastic, and speed the
50 time in which the band may be removed.
During the stretching and/or molding period
it is possible to form a flange 39 if desired at the
bottom of the band whereby the completed band
may be añîxed to the hat body.
This form of sweat band has the advantage of
preventing moisture, dust, body acids, and the
a complete immersion or complete covering of 20
the plastic, leather-like physical characteristics
such as stiffness are imparted to the cloth. Also,
when it is completely impregnated, a leather-like
feel is imparted thereto which is desired by some
However, by applying the plastic only on the
back thereof, similarly to the band 20E with a
backing 45, shown in Fig. 8, the inside or head
contacting face thereof is left with a soft silky
feel which may be desired by some people. This ,
construction also allows the cloth to absorb a
certain amount of sweat and moisture from the
head of the user, while the backing 46 functions
as a dam to prevent the same from seeping there
through to the hat or outside hat band to dis- .
color and mar the appearance of the hat.
The dam-like backing 45 illustrated in Fig. 8
and the impregnation with plastic 45’ described
in connection with Fig. 6 may be similarly applied
with the strip bands 2E] and 20C illustrated in the 40
Figs. 3 and 'l respectively. Such impregnation
or backing strengthens the joint 44 at the ends of
the strip so that there is very little likelihood that
lthe joint will ever become separated, and makes
it possible to dispense with the stitching 45 if 45
In passing, too, it should be noted that the
plastics 45’ and 46 may be in the form of a solu
tion, powder, or paste variously applied to the
bands, or it may -even be in the form of a sepa
rate strip of plastic material laid upon the fabric
and then pressed into the fabric. Also, it should
be noted that regardless of the way the plastic is
applied, and whether or not heat and pressure is
used, it is the fundamental intent of the present 55
process to stretch and set the fabric to a pre
like from seeping through the sweat band and
determined size, to render the band impervious to
thereby prevents these elements from passing
the passage of perspiration, and to maintain the
sweat band in the predetermined size by the use
of the plastic.
Specific descriptions thereof are now given:
A band of fabric 20 was immersed in an alco
holic solution of a partial condensation product
of phenol and formaldehyde 45’. Th-e band was
then applied to dies 23 and 24 and stretched to 65
the desired size. Heat, preferably above 180 de
through the hat or to the outer hat band to
60 spoil the appearance thereof. This is always a
very real problem in hats. Heretofore one of the
most effective means of preventing this adverse
condition has been to provide a separate water
resistant backing strip.
However, this entailed
65 the use of other mediums to hold the backing
strip to the sweat leather. Usually this medium
was stitching, which in turn adversely vformed
wicks conducting sweat and moisture to the hat,
thereby defeating the purpose, or at least mini
70 mizing the advantage of the backing strip. Also,
rubber which is usually used in such backing
strips deteriorates quickly, has a comparatively
short life, and is quickly affected by body acids
and the like.
75 The plastic 45', such as a compound of phenol
grees, and pressure in sufficient degree were then
applied to convert the resin to its final infusible
form. The ,resultant band was substantially
waterproof and because of the presence of the 70
artificial resin in and on the fibres the product
was unaffected by alkalis, acids, or any of the
ordinary organic solvents.
The above procedure can be modified in vari
ous ways. For example, the resin could be ap- 75
plied to the fabric base in the form of a varnish.
The polymerization of the varnish to a hard final
product could be accelerated and the final product
improved by stretching, and the application of
heat and pressure.
Also, the> impregnated bands produced by either
of thek above procedures could be processed in
various ways. Powdered partial condensation
product in what is termed the “B” ‘stage could
10 be applied to one or both sides of the impreg
nated base. Subsequent application of heat and
pressure will complete the condensation of the
coating of the powdered resin as well as the im
pregnant producing a band having a higher gloss

more thereof may be made from strips 2B'V with

in Fig. i7» wherein the side walls of the various `

Although the composite sweat bands are pref
erably made so that the thermo-plastic effectively
bonds the various plies of the band together, this
is not absolutely essential, for it is within the
purview of the present invention to mold the basic
both sides of the fabric band.
It is to be understood that the use of resins
other than the phenol-formaldehyde resins comes
within the scope of my invention. Such other res
ins are the glyptal resins, vinyl resins, .aro-matic

65 together bythe plastic and formed by stretching
and pressing in the apparatus 2i described herein
Similarly, the thermo-plastic backing 46 or
impregnation 45’ may be used to secure a rubber
70 ized or other water-proof strip 41 on the back
of a fabric head band 20 as illustrated in Fig. 11
to make the sweat band 201.
When it is desired to have an extra heavy
sweat band and one impervious to moisture, such

sweat band to the hat. The binder 45’ may be
used to secure the band to the hat as shown at
C in Fig. 13, when suitable heat and pressure is
applied (heat 180° or more).
Similarly, the' band may be secured to the hat 45
by providing a supplementary band of thermo
plastic 4B either adjacent the crown section of
the hat as at “a”, or adjacent the brim section
of the hat as at “b” in Fig. 1li, or at both loca
tions if desired. Application of suitable heat and 50
pressure secures the bands 48 to the hat. This
structure for securing the band to the hat has
- the advantage of dispensing entirely with the line
of stitching and thereby obviates the likelihood
of threads serving as wicks to carry sweat from 55
the head or sweat band to the hat itself.
All of the bands hereinbefore described may
be provided with a flange 39, or other deforma
tion, or may be left straight as shown by the
dot and dash lines 39' similar to the disclosure 60
in Fig. 6.
Other variations and modifications may be
made within the scope of the present invention
and portions of the invention may be used with
out others.
