13 Claims. (Cl. 131—39)
This invention relates to cigarettes and is par
Figure 2 is a section taken on line II--II of
ticularly concerned with an improved method and Figure 1;
apparatus for the production of ?lter tip and like
Figures 3 and 4 are sections on the lines III-III
composite cigarettes by uniting axially aligned and IV--IV respectively of Figure 1a; and
5 cigarettes or lengths of cigarette rod and ?lter tips
or mouthpiece portions by means of uniting
bands or wrappers.
The invention has for its primary object to pro
vide an improved method of and means for ap
1-;;. plying the uniting bands or wrappers around the
assembled lengths whereby the uniting operation
may be effected without any rolling or other
movement of the cigarettes, and whereby the
wrapping pressure may be maintained to ensure
l5 proper adhesion while the assemblages are being
fed axially.
The present invention furthermore renders it
possible, in a method involving the wrapping of
uniting bands around assembled lengths fed ax
20 ially to and from wrapping means, to effect the
initial application of the uniting bands to the
assemblages while the same are stationary and
positioned in registration with the means for ap
plying the uniting bands or wrappers.
25
According to the present invention, the lengths
to be united, assembled in line and after uniting
bands or wrappers have been brought into con
tact therewith, are fed axially and intermittently,
and the wrapping of the uniting bands or wrap
30 pers around the lengths to be united is effected by
the action of means moving lengthwise of the
assemblage in a direction opposite to the feed
movement thereof, the wrapping operation tak
ing place during a period or periods when the
:13 assemblage is stationary. The wrapping opera
tion is e?ected by means reciprocated in the
lengthwise direction of the assemblage, the wrap
ping movement in a direction opposite to the di
rection of feed taking place when the assemblage
#:H is stationary and the return movement coincid
ing more or less with the forward movement of
the assemblage.
Owing to the fact that during the forward
movement of the assemblage the wrapping device
4-?» moves substantially therewith, the wrapping
Figure 5 is a sectional view taken on line V-V

of Figure 1.
In carrying the invention into effect according
to one embodiment, pairs of cigarettes I, la and
interposed double length ?lter tips 2 or mouth
piece portions are fed respectively from hoppers 10
3, 3a and i into grooves in a drum 5 which is
moved intermittently, for instance by means of
a helical cam la engaging a gear 5a on the drum
spindle and mounted on a shaft lb driven through
bevel gears ‘is, to from the main shaft 6. Each 16
assemblage comprising two cigarettes I, la and
an interposed double length ?lter tip 2, is dis
charged in turn on to a belt 9 carried on rollers
53a and by which the assemblage is movecl'axially.
Preferably the belt 9 moves continuously and the 20
lengths constituting the assemblage are simul
taneously deposited on the belt 9 by means of
?ngers 8 carried by levers 8a pivoted on brackets
Ilia projecting from the bed M» of the machine
and operated, for instance, by eccentrics 6b the 25
straps 8b of which are connected to the lower end
of the levers 8a. Cams 50 on the shaft 6 co-oper
ate with levers 80 which through links 801 raise
the ?ngers 8, the downward movement thereof
being effected by springs 8e (Figure 3). In op 30
eration the fingers 8 are projected into circum
ferential slots 5b in the drum 5 so as to lie above
the leading assemblage and as the ?ngers 8
again move outwardly they are caused to drop
so as to engage the assemblage and roll the same
on to the belt 9.
The assemblage deposited on the belt 9 is posi
tioned by means of a guide 91) and is conveyed
axially by the belt 9 into an inverted c~shaped
guide 90 and up to a stop Hi. The stop I0 is
pivoted at lilo and is operated by means of a
cam llld mounted on a shaft Hie driven through
bevel gears up, 612 from the main shaft 6. The
cam llld operates the stop it through a push rod
pressure on each uniting band is maintained
throughout the feed movement with the result

The invention is hereinafter described by way
to of example with reference to the accompanying
diagrammatic drawings, in which:—
Figures 1 and 1a taken together show a side

means for applying a uniting band I I.
As shown'in Fig. 4, the uniting bands 1 l are fed
into position on an intermittently moving belt
l2 having perforations lZa and passing over a
suction box 53 having suction holes 130. and a
?exible suction pipe i311. The suction box I3 is
pivoted about the axis of a roller I30 on a spindle 55

I3d and is adapted to be raised and lowered by
stop plate 24. By the drum 23 the assemblages
means of a cam 8e on the main shaft 6 operating
are carried past a rotary cutter 26 by which the
assemblages are bisected to produce individual
on a lever I6 connected, by means of a link Ilia,
to the spindle I3g of a roller I3e around which
the. perforated belt I2 passes, a return. spring
Iiib being provided. The belt I2 is led on to the
suction box I3 over a stationary suction box I5.
Thus, after an assemblage is positioned as shown
in Figure 1, the operation of the cam 6e raises
10 the suction box I3 and thus presses the leading
uniting band I I into contact with the assemblage.~
The cam Be is arranged to maintain the suction
box I3 in the raised position while the stop ID is

semblages are positioned between the stop plate
24 and a corresponding side plate 24a and are
maintained in the grooves in the drum 23 by
means of curved guides 28. The drum 23 may
be driven intermittently by means of a helical
cam 25 mounted on a shaft 25a driven through 10
gears 25b, 69 from the main shaft 6.
The cigarettes are ?nally discharged down in
released and the assemblage is discharged axially

belt 29 passing over a roller 29a.
