Vide a die which will act upon the wrapper strip
to cut out portions thereof in accordance with
a desired shape which is to be obtained.
At the same time, a cutter device may be em
Cl ployed to sever the strip before, during or after
the die cutting operation.
After the die cutting operation, it has been
found most desirable then to emboss, imprint or
and manufacture hair waving pads of different
constructions.

This invention will appear more clearly from the assembly of the ñannel sections with the
the following detailed description when taken in wrapper strip.
Referring particularly to Figures 16 to 18, the 30

showing by way of example, preferred embodi
ments of the inventive idea.

methods of operating the machine to assemble
wrapper material A and the flannel of felt ma
terial B are fed forwardly to the left, as indicated
by the arrows 25.
The absorbent material B' may consist of flan
nel, doubled so that its opening will be adjacent 35
the wrapper, as indicated in Figure 16, so that its
opening may be away from the wrapper, as indi
cated in Figure 17, or it may consist of an un
folded sheet of material as indicated in Figure 18.
Strips of filter paper and/or strips of felt may 40
also be utilized alone or in combination with other
absorbent materials as indicated in Figures 16
and 17.
The wrapper strip A on the other hand may
consist of a single strip of material, as> indicated 45
in Figure 16, or it may be folded to enclose ‘a foil
strip C as indicated in Figure 17.
In Figure 18 the wrapper D preferably con
sists'of a strip of foil and paper paraflined or
waxed together, which may be subjected to the 50
action of a heater or separator element E to per
mit a separation of the edges and insertion of the
absorbent Vmaterial at the proper position where
it may be sewed in. location during subsequent
55
operations of the machine.
Referring to Figure 1 the guide for the wrap
per strip A is indicated at F while the guide for
the ñnal strip is indicated'at G.
It is desirable in making the pads, as indicated
at the left of Figure 16 and in Figure 12 that the 60
flannel strip be of substantially lesser length than
the wrapper strip' to which it is sewn and for this
reason it is desirable to have an intermittent feed
26 of the flannel with a substantially continuous 65
feed 25 of the wrapper strip A.
Referring to Figure 1, the continuous feed of
the wrapper strip A is obtained by the continuous
rollers I-I which are provided with an adjustment
S enabling regulation of the rate of feed, while 70,
the intermittent feed is achieved by means of the
intermittent mutilated rollers I.
'
The rollers H continuously draw the wrapper
sheet A through the sewing machine J and the
intermittent rollers I` intermittently advance the

Referring to these figures, it will be noted that
section T of the absorbent strip may be varied.
After the section T has been cut and inserted
by the devices L and M in the continuously feed
ing Wrapper strip A, it is picked up by the
mutilated feed rollers V (see Figs. 1, 2 and 4).
These mutilated rollers consist of an upper roller
200 and a lower roller 20|, the upper roller being
connected to a shaft 202 which bears. at 203 and 50
the feed rollers H include an upper roller I4I and

lower roller |42 having respectively the shafts |43

The shaft |43 is connected to the driving'gear

ing gear |56.
The rollers |4| and |42 are preferably provided
with a rubber surfacing and the pressure between
them may be varied by providing the upper roller

|4| with a bearing yoke I5| which has adjust
able slide members |52 and |53 carrying the
shaft |43. Said members |52 and |53 fitting into
recesses or vertical slots in the members |45 and

The pressure between the rollers |4I and |42
may be varied by the adjusting screw |55, the
70 lower end |56 of which contacts with the flat
tened portion |51 at the top of the yoke I5I.
The scr-ew |55 is carried by the plate |59 which
is bolted at |60 (see Fig. 7) to the upwardly ex
tending ñange |6| from the transverse member
75 |62 of frame |41. The member |62 carries Ythe
having bearings in the flange |I8 and at 2|6 in
the frame I I9 and driven by an intermediate gear
2I1 between the gears 209 and 2|0 (see Fig. 6).
The upper roller 200 (see Figs. 1, 2 and 4) is
driven by the gear 209 on the end of the shaft 202
which in turn is driven through the gear 2 I 0 from
the gear 2 I | on the shaft 2 I2 (see also Fig. 3).
After the ñannel or felt strip B has been cut in
to the sections T, as indicated in Figures 16 to
18, and inserted between the opening device M
between the plies of the wrapper strip A, as indi
cated in Figure 4, the wrapper stripA together
with the absorbent section T after it has been
picked up by the full diameter portion of the roll
ers 200 and 20|, will be moved up to the sewing
machine J.
