Cam lever 624 carries a cam roller 628 engaging with a
blank, is inserted, the cam 544 is slightly rotated in an
anti-clockwise direction so that the cam roller 542 of this
pocket rolls from the high portion of cam 544 onto its
low portion and thus closes the jaws of this pocket before
the turret is indexed. The jaws remain closed while the 25
turret is intermittently rotated past the various folding

the proper relative horizontal motion between bars 600
and 606 effects an opening and closing of the pleating

Therefore, when the cigar carrying pocket P of the tur

When the cigar with its wrapper blank is about to be
inserted in a pocket at the injecting station, as shown in
FIG. 10, the jaws 536 of said pocket P are open but
close quickly after insertion by the vertical plungers 438.
After being pushed into the pocket, the Wrapper blank
covers three sides of the cigar, namely, the two sides
and the top thereof, thus forming a U-shaped envelope
with the two sides of the wrapper blank projecting straight
disturbing the thus created pleat during the following
creasing operation, the pleating ?ngers 592 remain in en
gagement with the pleat while a top and bottom creasing
plate 632 and 634, respectively, engage with the end of
the envelope and crease the pleat to form a flat tab-like
end closure as illustrated in FIGS. 17 and 18. The plate
632 is mounted on a pair of spaced arms 636 mounted
on a shaft 638 while plate 634 is mounted on a pair of
?rst downwardly projecting side flap is folded over the 40 spaced arms 640 mounted on a shaft 642. On shafts
638 and 642 is mounted a gear 644 and 646, respec

down and out of the pocket P as shown in FIG. 11. The
plate 564 as shown in FIG. 12.
Folder plate 564 is secured to a suitably shaped mem
ber 566 which is pivotally supported and suspended from
two arms 568 and 570. The latter is pivotally sup
ported by a stud shaft 572 held by a suitable frame
member while arm ‘568 is pivotally supported by the shaft
522. To member 522, by means of a pin 574, is also
pivotally connected the free end of an actuator arm 576
loosely supported by the shaft ‘460. Integral with and
extending from the hub of arm 1576 is a cam lever 5-78
carrying a cam roller 580 engaging with a suitable cam
582 mounted on the main drive shaft 304.
After the ?rst side ?ap is folded over the bottom of
the cigar by the folder plate 564, the latter remains in its
forward position until the cigar carrying pocket is ad
vanced towards the next station during which time the
second downwardly projecting side ?ap contacts an arced
stationary folder plate 584 which folds said second ?ap
tively, both gears meshing with each other. From the
hub of gear 646 extends an arm which through a suitable
link is connected to the free end of a cam lever carrying
a cam roller engaging with a suitable track in drum cam
620. It is self-evident that an oscillation of said gears
644 and 646, imparted by said cam, cause the creasing
plates 632 and 634 on arms 636 and 640, respectively,
to move towards or away from the end fold of the en

The creasing plates 632 and 634 ?rst engage tightly

when the turret starts indexing and moves the cigar

the pleated and creased ends of the envelope engage

and 2.2. In order to prevent the pleated and creased ends
over the already folded one as illustrated in FIG. 13 of
of the envelope to open up while being carried by the

trical components, although reference will also be made
shown in FIG. 2. It is self-evident that the raising of
arms 664, as described heretofore, causes the bell crank
lever 683 to swing or rotate in such a manner as to ef
fect, through link i682 and arm 679, an engagement of
the upper folding member 656 with the raised lower fold
ing member 658 and thus squeezing and sealing the end
fold between said folding members as illustrated in FIG.
22. A tension spring 686 connecting the two opposed
upper folding members ‘656, one of which is located at
each side of the turret, (FIG. 2) is provided to assure
the required pressure necessary for sealing. Another ten
sion spring 687 con?ned between each bracket 670 and
the top edge of the lug 680 of each arm 679 is employed
to the other ?gures which show the physical apparatus.
The machine is powered in ‘a conventional manner by a
one-half horse power, three-phase, motor 766 connected
to two-twenty line voltage.
The ‘motor is linked to a gear
