202 formed longitudinally of the paper. The lon

indicated. The following is a description of the
method and apparatus for forming this paper:
Referring to Fig. 1 of the drawings the inven 25
tion is illustrated as embodied in a machine com
prising a crinkling mechanism A, a second treat
ing mechanism B and a drying mechanism C.
'I'he crinkling mechanism A may be of any suit
able or standard form comprising, for> example, a 30
framework indicated at I 00, a tank |0| with a per
forated drum |02 immersed therein over which
the paper stock indicated at |03 runs and is mois
tened thereby, a tank |04 in which runs the crin
kling roller |05 and a doctor blade |06. The pa 35
per stock |03 after it is crinkled is conveyed by
a. belt conveyor v|0`| either directly to a belt con
veyor |08 leading to the drying mechanism C, or
directly to >a conveyor mechanism indicated gen
erally at |09 leading to the mechanism B, and 40
then ultimately to the conveyor |08. At | I0 is in
dicatod diagrammatically a means for printing or
stamping a trade-mark upon the paper stock |03,
while the paper stock is fed from a roll |03’.
The mechanism B, for forming the longitudinal 45
folds 202 and rendering the stock |03 stretchable
'at right ang1es to the crinkling effected by the
mechanism A, comprises a comparatively large
and elongated cylindrical drum | which is closed
at its ends by plates 2 and is carried by a shaft 3 50
by which the corrugating and drive cord'may be ‘ which. is journaled in suitable bearings 4 mounted

the guide sheaves I9 are arranged in the form of
a V, as more particularly indicated in Figs. 6 and

25 a width larger than the width of the groove 1
with which it is associated.
'I'he rollers II are lcarried by shafts I3 which
are freely journaled in bearing'members I4 which
in turn are mounted upon the circular disposed
l30 L-beam members I5, the bearing members I4
being secured -to the beams I5 in any suitable
manner, as for example by the bolts I6. " The
circular beams I5 are supported in any suitable
single guide sheave in the form of a roller l23 20
with a groove 24 cooperates with the centrally
disposed presser roller I I' which forms the groove
1' in the center (Figs. 7 and 10), while for form

following pair of presser rollers are provided, and
then a second pair of guide sheaves 26, 26' co

The pairs of sheaves 25, 25', -
26, 26', 21, 21’ etc. are fixed to their respective 30
shafts I3 to rotate therewith, while the presser _

other end around a common roller I2. The roller
I2 is illustrated as being without guide grooves
for the cords but such grooves may be provided,
if desired or necessary. In the particular em
bodiment shown the cords I8 are formed of loops
of a single cord which is threaded aboutthe
sheaves and presser rollers and the common »
`roller I2 instead of the provision of a multi
plicity of separate cords for each pair or groupl
of sheaves and presser rollers and the drive mech
anism. This single cord arrangement is pre
ferred among other reasons because of the ease
of drive and the facility with which the ten

pass around the drive roller 88 and idlers 98, 91,

of leading to drum or roller 88 it leads to a guide ,
members,5 and driven by a sprocket 98, as more
particularly hereinafter described. A sufficient pulley |88 and from thence to another guide
pulley IGI and from there radially inwardly to a
Ul number of the loops of the single cord I8 are
carried around the drive drum 88 to positively sheave 61. This loop then continues about the

threading of the cord a series of idler rollers 9|, from 92 and the remaining four over idler 9|,
92, 93, 94, 95, 96, 91 and 98 are journaled in the
framework and spaced from and about the drum
I50'in the manner generally indicated in Fig. 5,
these idlers guiding the cord or cord loops to the
sheaves and presser rollers in a substantially
radial direction. There are .also provided two
guide pulleys 99 which are carried by suitable
brackets 99’ up above the drum for guiding the
cord to and from a tension maintaining mecha
nism |58, the latter comprising a multiplicity of
weighted pulley-blocks |5I, in the particular em
bodiment shown there being three of such
weighted pulleys which are guided on suitable
guides |52. AA cord is guided by the pulleys 99 to
and from stationary pulleys |53 of the tension
ing mechanism |50, While other stationary pul
leys |54 are disposed between the movable
weighted pulleys I5I. By means of this tension
ing mechanism the exact tension desired upon
the cord may be maintained, as for example by
mounting different weights |55 upon the movable
pulleys, and the slack‘of the cord is at all times
taken up. The cord or belting may be of cot
ton, such as sash cord, or other soft and pliable
material.
'
The cord may be threaded in any suitable man
ner, but in the particular embodiment shown it
is threaded generally as follows:
'
Taking the cord, for example, as it leaves the
left hand pulley 99 in Fig. 5, it passes over the
guide rollers 93, 92, 9| and then radially in
wardly to the guide sheave 24. From there it
passes under the following presser roller II’ into
the central groove 1’ and then around the drum
I to the common roller I2. From here it passes
about the driving drum 88, under idler 98, over
idlers 91, 95, 93, 92 and 9| and into the sheave
25', then again around the drum I to the roller
I2 and about the same circuit back to sheave 26',
and so on to sheave 28'. The nextvsix loops fol
low in the same general direction and pass around
the last loop leaving 9| going to sheave 25 thence
around the drum to roller I2 and from _the roller
I2 over roller 88, idler 98, 91 and to the right
hand take-olf pulley 99 of Fig. 5.
It is clear from the above description that in
the formation of the groove in the paper stock in4 .10
t-he central groove 1' the cord I8 is in actual con
tact with the paper inside the groove for prac
tically the whole circumference of the drum,
namely from the first presser roller I I' (Fig. 5)
all the way around to the common guide roller I2 45
and in the formation of thegrooves in the paper
stock from the center outwards in both directions,
the length of the cord in actual contact with the
paper in the grooves gradually diminishes untilWe reach the last two presser rollers II" (Fig. 5)
when the length of cord in actual contact with
the paper in the outside grooves is from a point
some distance rearwardly of the roller I2 to
slightly beyond the presser rollers II”.
The next step in the process after the forma- ,
tion of the deep» longitudinal grooves in the
paper stock by means of the mechanism abo-ve
described isl the pressing of the paper stock into

The bracket |46 is adjustable to the dotted
positions indicated in Figs. 4 and 5 to permit, if
desired, the delivery of the crinkled stock |03
direct from the conveyor |01 to the conveyor
|08 leading to the drier C. This enables the
production of a paper which is merely crinkled
for stretchability in one direction only in which
case the manually operated clutch |83 is disen
ga-ged to stop the rotation of the shaft |80. This
bracket |45 may be, of course, adjusted and heldin any position' by any suitable mechanism but
the means shown diagrammatically for this in
the particular embodiment shown comprises a
pin |90 in each arm |46 which pin when the arm
is in its lower position engages holes |9| and
when it is raised to the position shown in Figs., 4
and 5 these pins engage holes |92 and the frame
and sheaves to progressively convey the paper
stock between the cords and movable surface to
l form longitudinal corrugations in the stock, said I
|30.
An- important feature of my improved machine
as above described is that the crinkled paper is
conveyedV in moist and heated condition from
the crinkling cylinder through the corrugating
and flattening devices, and this is accomplished
without materially stretching the crinkled paper
longitudinally and without danger of lrupturlng
or otherwise weakening the ñbers of the paper.
The mated conveyors |3| and |32 bodily carry
the paper from near the crinkling cylinder toI
a position in proximity to the corrugating cylin
30 der, and the cord or belting cooperates with the
groovedy corrugating cylinder to- bodily carry the
paper to a position in proximity to the flattening
rolls. Only sufficient longitudinal tension is
placed on the paper as it passes between th'ese
35 devices to take up slack soV as to prevent wrin
kling. As the crinkl'ed paper leaves the mated
conveyors |3| and _ |32 it is gradually guided
toward the bottom of the grooves in the cylin
ders by the inclined portions of the belting which
40 extend from the rforward sheaves to the presser
rolls ||, and the presser rolls acting through the
cords being formed of a continuous cord,` means
for distributing the loops of the cord to and
from the respective sheaves, and a single means
for maintaining the desired tension on said cord.
