invention: involves the provision
of suitable pad folding mechanism which is par
lii ticularly adapted to folding the end flaps or tabs
_.
For supporting the forward end of the pad
strip while the said forward end is being severed 50
from the supply strip, there is provided a hor
izontally reciprocable table 9. A stationary strip
‘per member 9a serves to strip the severed pad’
from the table 9 when the latter is moved out
wardly to the position shown in Fig. 11, and a
2
2,184,459
plurality of forwardly and downwardly inclined
?ngers 9b are provided for insuring proper de
position of the severed pad sections on the cover
strip 4 which is traveling in a direction extend
ing crosswise of the direction of feed of the pad
supply strip 1.
The pad supply strip 1, in the pad-making ma
chine above described, is of a width substantially
equal to the length of the desired pad sections
10 and the length of the front end portions of the
strip which is cut therefrom constitutes the width
of the severed pad. In the pad-making machine
above described, the cover material strip 3 is of
greater width than the width of the pad supply
15 strip 1, as will readily be understood from a com
parison of the width of the respective supply
strips as shown in Figs. 10 and 11. However, the
' pad sections which are severed from the supply
strip ‘I are of an even smaller width than the
20 width of the supply strip ‘I so that the pad sec
tion is oblong in ‘shape. The pads are deposited
in longitudinally spaced relation on the strip of
covering material intermediate the width of the
latter so as to leave marginal side portions of
25 gauze projecting sidewise from the opposite side
bearings in the frame I0 and the shaft I6 of the
roll I4 is journaled in suitable bearings in the
frame I1 which supports the folding mechanism
of the present invention. The shaft I5 extends
outwardly on both sides of the roll I3 and is pro
vided with a pair of sprocket wheels I8--I8, one
on each side of the roll I3, and is adapted to
turn with the roll. The sprocket wheels I8-—I8
receive a pair of sprocket chains I9-I9 which
are also threaded over a pair of sprockets 20—20 10
at the other end of the machine. It will be ap
parent that the chains I9—I9 and the conveyor
belt I2 are adapted to travel together at the
same speed, since the roll I3 and the sprocket
wheels I8—I8 are of a size to produce this result. 15
Suitable means may be provided for maintaining
the chains taut and may comprise bell cranks I9a
pivotally mounted on the frame I1 and having an
idler pulley mounted at the end of one leg and
adapted to engage the lower reach of the chain 20
and having a weight suspended from the end of
the other arm as shown in Fig. 1. The chains
I9-—I9 are connected at intervals by means of

is advanced intermittently and pad sections sev

.
Suitable folding devices 90 are provided along
the table over which the covering material strip
35 is' fed, these folding devices being of the type
which directs or-folds the‘marginal side portions
of the covering strip upwardly and transversely
over the top of the median portion of the cover
ing strip and over the top faces of the longi
tudinally spaced pad sections. '
The details and the mechanism for actuating
the above described pad making mechanism are
fully described in the said .copending application
of William Bauer, and since such details of con
struction and operation do not constitute a part
of my invention, the same need not be more fully
described herein.
It will be seen that the pad making machine
above described serves to deliver a series of con
nected sanitary napkins to an inclined chute
I0’ and a rotary cutting or shearing mechanism
indicated at II (Fig. 1) is provided for severing
the napkins intermediate successive pads so as
- to form end ?aps or tabs 22-22 for each pad.
55 The chute I0’ and cutting unit II is suitably sup
ported on a frame element III as clearly shown in
Fig. 1', and the details of the cutting mechanism
I I are fully disclosed in the above referred to ap
plication of William Bauer. The details of the
60 cutting mechanism were not invented by me, and
'
The conveyor belt I2 is adapted to deliver the
pad to a supporting conveyor belt 24 which ex 30
tends around suitable drums 25 and 26 which are
each rotatably mounted in suitable bearings on
the frame H. The supporting conveyor belt 24
is adapted to be intermittently moved and for
this purpose I provide the following mechanism. 85
The shaft 21 of the drum 25 extends outwardly
beyond its bearings as best shown in Figs. 2 and
4. A sprocket wheel 28 is rotatably mounted on
the projecting end of the shaft 21 and is pro
vided with a ratchet tooth faced hub 29. The
sprocket wheel 28 is driven from any suitable
source of power and in the present instance I
contemplate driving this sprocket by means of a
chain 30 (Fig. 1) which is threaded over a suit
able sprocket wheel 3| which, in turn, is mounted 45
on and secured to the shaft 32 of the sprockets -
20-20. The shaft 32 may be rotated by suitable
means such as a sprocket 33 secured thereto and
adapted to receive a chain which may be driven
from any driven power shaft. It is, of course, 50
obvious that I may apply the driving power at
either end of the machine, for instance, as above
explained, to the shaft 32, or to the shaft I5 or to
any other suitable shaft.
Rotation is transmitted from the sprocket ,
wheel 28 to the shaft 21 by means of a clutch
member 34 which is axially slidable but non
rotatably mounted on the projecting end 35 of the
shaft 21. A coil spring 36 interposed between the
- given. Su?ice it to say that any form of cutting
outer face of the clutch member 34 and a collar 60
31 secured to the outer end of the projection 35 .
normally urges the clutch member 34 into en
mechanism adaptedto the purpose may be used.
The pad making machine delivers a pad which
65 consists of a pad of soft ?lling material wrapped
gagement with the ratchet tooth face 29 of the
sprocket 28. The clutch member 34 is intermit
tently forced out of engagement with the ratchet 65
hence a detailed description thereof need not be
with a covering of gauze or the like and as clear
7 1y illustrated in Figs. 1 to 5, the ends of the
wrapper form flaps which projectbeyond the re
spective ends of the ?ller pad. As the pads are
70 delivered from the pad making machine, they are
received, according to the present invention, on a
continuously moving conveyor belt I2 which ex
tends around suitable rolls I3 and I4 which are
provided with shafts I5 and I6 respectively. The
shaft I 5-of' the roll I3 is journaled in ‘suitable
tooth face 29 by means of a forked arm 38 which
straddles a portion of the clutch member 34 and
engages the opposite faces of the groove 39 in the
clutch member. The forked arm 38 is secured to
a rock shaft 40 journaled at one end-‘in a bracket 70
4| securedto the frame I‘! and at its other end
in a bracket 42 secured to the frame II). The
rock shaft 40 may conveniently be rocked by
means of a cam. arm 43 secured thereto and
adapted to be rocked by means of a rotating cam
9,134,459
44.
The rotating cam 44 is preferably secured
to the shaft I5 so as to rotate therewith. It will
be apparent that when the cam 44 forces the cam
arm 43 inwardly (Fig. 2), the forked arm 38 will
cause the clutch member 34 to be disengaged from
its cooperating member, whereby movement of
the supporting conveyor 24 will be stopped.
In the apparatus thus far described, the con
veyor belt I2 is adapted to receive the pad with
10 its ?aps extending from its ends from the pad
_ making machine and the ?ap receiving members
receive the respective end ?aps thereover. The

the pad forwardly under the folder 46. The
forward end ?ap 22 which has previously been
deposited on the top of the folder, when the cor
responding‘ ?ap receiving member 2| is carried
thereover, is folded upwardly and inwardly over
the corresponding end of the pad, and where the
?aps are of sumcient length, over the ?rst folded '
flap. The top' 41 of the folder is preferably in-.
clined downwardly so as to press the forward
end ?ap closely against the top of the pad as it 10
moves thereunder and the depending side ?anges
48 are operative to square up the side edges of the
conveyor belt I2 is continuously driven by the
pad, As the pad is propelled ‘through the last
above described chain driving means through the
folding operation, it is delivered to another re
ceiving conveyor 52 which is adapted to convey 15
the article to ‘a packing machine or any other
desired receiving means.
As the pads are received from the pad making
machine, the ?aps project from the ends thereof ,
and from both the top and bottom sides of the 20
pad. I ?nd it desirable to crease the ?ap ad
15 sprocket 33, shaft 32, and sprockets 20-20 over
which the chains H! are threaded and through
which chain the roll i3 is driven by means of the
sprocket l8 secured to the shaft i5 as above de
scribed. ‘Suitable means such as a gear train
20 comprising gears 1|], ‘II and ‘i2- is provided to
synchronize the movement of the cutting mecha
nism ||,.conveyor l2 and chains Iii-i9, so that
the conveyor and ?ap-receiving means 2| on the
chains |9—|9 will always-be brought into proper
25 position to receive the pads as they are severed
and discharged from the pad making machine.
The conveyor l2 ,carries the article or pad for
wardly to the intermittently driven supporting
conveyor 24. When the article is delivered and is
properly positioned on the supporting conveyor
24!, the latter is stopped. The conveyor l2, how
ever, and the chains Iii-l9 with their connecting
cross members or ?ap receiving members 2| con
tinue to move forwardly. During the continued
forward movement of the ?ap receiving members
2|, they are guided in a path inclined upwardly
relative to the plane of the conveyors l2 and 25.‘
This is accomplished by means of guides 45 which
are supported by the frame H and on which the
respective chains |9—|9 ride as best shown in
Fig. 1.
, When
the rear ?ap receiving member 2|
reaches the position shown in Fig. Sadjacent the
rear end of the pad, it will have been raised to
45 a position somewhat higher than the top of the
pad and will be in a position to ride over the top
jacent the end of the pad so as to effect a cleaner
or sharper fold and for this'purpose I provide
a creasing bar 53 which is carried by a sprocket
54 rotatably mounted on a suitable bracket 55,
carried by the frame IT. The sprocket 5d meshes '
with one of the chains l9 and is thereby rotated.
The creasing bar 53 is mounted in such a position
on the sprocket that as the sprocket rotates, the
bar will engage the forward ?ap 22 closely ad 30
jacent the front end of the pad and will be op
erative to force the flaps downwardly adjacent
the forward end of the pad into a position sub
stantially as shown ‘at the right hand end in
Figs. 5 and 6. It will be apparent that when the
forward end ?ap is turned upwardly and inward
ly over the pad that the initial fold will be along
the lower front edge of the pad and that the ?ap
will then lie closely vand smoothly over the end
and top of the pad. It will be understood that
the‘ creasing mechanism just described may be
so timed as to effect creasing of the ?ap at the .
rearward end of the pad instead of the one at
the front end, and also that the same mechanism
could be duplicated if it be desired to crease both 45
end ?aps.
'
.
For insuring the proper positioning of the pad
on the supporting conveyor 25 and for improving
inwardly and over the pad as will be readily un
derstood from an inspection of Fig. 6. When the the creasing of the flap at the forward end of
member 2| has reached a position over the rear the pad, I provide a member 55 which extends 50
end of the pad, the guide members 25 are in-' across the width of the‘pad and is mounted on
clined downwardly so as to cause the member 2| ' a rod 51 which is pivotally supported by a pair
to be lowered into contact with the top of the of brackets 58-58 which are supported by the
pad; The chains iii are caused .to follow the frame. The rod 51 is adapted to be rocked in its
guide 55 downwardly by means of guides 65—65 bearings by means of an‘ arm 59 and connecting 55
which ride over the tops of the chains as best rod ‘60 whichis pivotally connected by means
shown in Figsf’l and 4. By this means the ?ap of a crank pin 6| to a collar 62 secured to the
of the pad whereby it will carry the rear end flap I
is pressed tightly against the top surface of they rotary shaft 63 of the cutting mechanism | I. As
- pad and the pad itself is somewhat compressed the collar 62 rotates, the rod 6|! is reciprocated
and smoothed out. Further movement of the, and the shaft 51 thereby rocked. The member 50
chains |9-_|9 and of the ?ap receiving member
2| carries the member 2| upwardly over a folder
t6 and around the‘ sprocket 2|]. As the member
' 2| leaves the pad, the supporting conveyor 25 is
65 set into motion so as to advance the pad whereby
folding of the forward ?ap is accomplished.
The folder 46 comprises a top plate M having
depending side ?anges 48—48 which are angu
larly inclined from a wide forward end to a nar
row
rear end. The folder 55 is stationarily
70
mounted by suitable brackets 59 on a bed plate
5|! which is supported by means of the frame ill
and brackets 5|—5| secured thereto. As will
be understood from an inspection of Figs. 5 and 6, ,
55 forward movement of the» conveyor 25- carries
56 being secured to the shaft 51 is thereby swung
upwardly and downwardly into positions as in
dicated in Figs. 5 and 6. When in the position
shown in Fig. 5, it is‘operative to prevent forward
movement of the pad due to frictional engage 65
ment of the folding member or flap receiving
member 2| or other causes and it also further
creases the forward end ?ap adjacent the for
ward ‘end of the pad. Movement of the member
55 is of course properly timed with the move
ment of the intermittently operated supporting
conveyor 25 was to permit forward movement
.of the pad when the conveyor is moved to ad
70
vance‘the pad. “Adjustment of the member 55
may be had by moving the brackets 58 upwardly
w
2,184,459
or downwardly and for this purpose I mount the
brackets 58—58 on the side frames by means of
a clamping screw 64 which passes through a suit
able slot in respective brackets and threadedl
engages the frame.
'
While I have found that frictional engagement
between the supporting conveyor belt 24 and the
pads 23 is ordinarily sufficient to cause the pad
folding operation being effected during a period
of rest of said supporting member, means for
creasing the forward end ?ap adjacent the for
ward end of the package, and means for folding
said forward end ?ap over the package at the
crease.
.
4. In a machine for folding ?aps which pro
ject from opposite ends of a package, the com~
to move with the conveyor or to stop therewith,
10 I may provide additional means for insuring more
bination of an intermittently movable support
ing member,~ a continuously driven conveyor 10
positive engagement therebetween. Such means
may comprise a plurality of small pins projecting
upwardly from the conveyor 24 and adapted to
engage the bottom of the pad.
I have thus provided a machine of the char
15
acter described ‘which is simple in construction
having few parts and ‘without delicate adjust
ments and which is, therefore, not apt to-become
out of working order and which is entirely auto
adapted to successively receive the packages hav
ing flaps projecting from their opposite ends and
to successively deposit the same on said support
20 matic in its operation. I am aware that various
changes in construction, proportion, and arrange
