lin GreatBritain January 31,1936` n l 17 cleans.` (C1. 1x1- 94) l (Granted under the provisions of sec.l 14,7actof M-i'h 2, 1927; 357 G. 5) I l This invention relates to the manufacture of lter tip or like composite cigarettes by uniting cigarettes or lengths of cigarette rod and filter tips or mouthpiece portions by means of uniting bands of cork or the like.

The present invention Ihas for its object to provide improvements in'theproduction of lter tip cigarettes rwhereby the application of the runiting""bands to and around the assembled lengths to be united may be effected with cer tainty and precision so 'as to `ensure constant and eflicient operation -under ordinary working con-` ditions and at the Sametime to secure a product which is consistentlysatisfactory.

More speciiically the present invention has for its main object to effecta vpreliminarywrapping i of the `uniting band around part of the circumference of the assemblage without rotation or axial movement of the same.

A further object is to effect the wrapping of the uniting bands around the 4assemblages partially or :wholly while theassemblages are being carried `laterally without rotation.

'A further object is to .provide apparatus for carrying out the method vherein described.

The invention is hereinafter described by way of example with reference `to the accompanying diagrammatic drawings, in which- Figure 1 is a part sectional side elevation illustrating one embodiment according `to the invention; i f

In carrying the invention into effect accordin to vone embodiment and with reference to Figures l and 2 of the accompanying diagrammatic drawings, the assemblages i, the component parts of which are to be united and which generally consist of'vtwo cigarettes or lengths of cigarette rod an' interposed. ydouble length lter tip or mouthpiece portion, are delivered"` from hopper or other means (not shown)` into grooves 2a inia drum 2 Vin which grooves 2a. the assemblages are retained by fixed `guides 2b. From the drum Zfeach assemblage is' .transferred in turn by the provision of arotary Acarrier 3 in the form of a suction drum having armsta with 5f `concave extremities 3b and suction holes 3c, the latter communicating with a suction chamber 3d which in turn communicates through a hole y 3e with a bore 3f vin the spindle 3g connected to K a suitable source of suction. Each arm 3a `is', in K10 i four parts, the twoV outer parts engaging the two cigarettes and the two innerparts` engaging the double filter tip, `the spacing of the four parts ,providing circumferentially extending slots in` which the guides 2b anda suitably slotted part l5 vof the member 'l to be hereinafter referred to mayextend. The suction' to the arms 3a iscut" `off by a fixed member Sh'during the part of the travel from the releaseypointto the point `ofpick up from the drum 2. f Each assemblage I is in turn brought into contact with a previously `pasted uniting band 4 of f cork or the like carried on a suction drum 5 having suctionI holes 5a and a suction cut-off member y5h. As shown, the assemblage contacts 25 with the band Il at a position towards its leading end and the assemblage with the band 41 applied `thereto is carried around on the arm 3a into engagement with the drum 6. The drum 6` is formed with transversely extending slotsr 6a 30 (Figure 2) in which resiliently mounted members 6b normally are disposed so as to lie more or less iiush with the periphery of the drum. As shown, the members Gibmay be carried on arms 6c pivoted at 6d and influenced by light tension springs 35 6e.` Inthev projecting movement of the `assemblage towards the drum t, the leading part of the band 4 is engaged by the respective member 6b and thereby partly wrapped around the assemblage, tion shown in dotted lines in Figure 1 it is pressed into the slot 6a in. the drum againstthe resilient member Scand, as shown more especially in g Figure 2,' the band li is thereby wrapped around approximately half the circumference 'ofthe as-` 45 r oFFicEff N f As the assemblage approachesthe posi- 40 y a table 8b and the assemblage is rolled between the belt andthe member 1 so as tocomplete the wrapping of -the uniting band 4 around the assemblage in a manner known per se, the beltv 3 by the gears 3i, Gf. The roller 8a may be driven` by the gears 3i, 8c.

As viewed in Fig. 1, the gear wheel 5c is disposed slightly behind the gear wheel 6f so as not to foul the latter, and it will be understood that the teeth of the gear wheel 3i are made wide enough toA mesh with both the wheels- 5c and rI'J; a similar arrangement is hereinafter described with reference to Figs. 3 to 8. and-is most clearly seen in Fig. 8.

In a modication, as illustrated in Figures 3 to 8, the assemblages I are transferred from the drum 2 by means of radial arms 3a on asuction carrierl 3 as before described, but in this embodiment each assemblage contacts with the n r uniting band at a substantially middle position, as

y shown in Figure 3.

The assemblage with the vuniting band 4 attached is carried around in relation to a drum ID having radially projectible members Ilib, disposed in slots Illa and having U-shaped outer ends forming spaced members Ic. Tongues IUJ formed in the members Ib, as shown in Figure 7, engage in grooves Ig formed in the walls of the slots Illa; so that the members III?)` are constrained to'remain square with respect to the 'aXis of the drum I0. The members I 0b are fitted with rollers Id engaging in a cam groove in a fixed cam disc II, the cam groove being profiled at IIa so that at this position each member Illbis projected radially, as shown in dotted lines, so that-the members Illc act to wrap the band 4 around substantially half the circumference of the assemblage. At this point the suction to thev arm' 3a is cut off by the member 3hland on withdrawal of the member Illb the assemblage is carried thereby into the slot Illain the drum Ill. The projecting parts of the uniting band 4 are wrapped around the assemblage, while the same is being carried laterally by the drum I0, by the action of sleeve segments I2 carried byan end plate IZa which, while driven in the same direction as the drum I0, has a differential movement with respect thereto so that during accelerated movement of the plate I2a one segment I2, as shown in Figure 4, moves forward to' wrap overA one of the projecting parts of the uniting band 4 and then,

lbe delivered on to a conveying belt IB passing over a roller Ia. The carrier 3 and the drums 2 and 5 may be geared together by the means shown diagrammatically in Fig. 8. The drum ID may be geared to the carrier 3l by means of the The carrier 3 may be geared to the drum gears 3i, I Ile. The plate I2a may be mounted `on a sleeve fitted with a separate gear Wheel I2b which is driven with a differential motion in relation to the gear IIIe, for instance by a gear train embodying a gear I3 meshing with the 4gear liptical or other varying ratio gears I4, I5 and a gear I6 meshing with the gear |21).

It will be understood that in all cases single 'lter tips may be united to single cigarettes and that where a double filter tip is interposed between and united to a pair of cigarettes, the product has to be subsequently bisected. Furthermore, if desired, any suitable number of lengths may be united by the application of two or more uniting bands to produce a rod which is subsesuction carrier having radial suction arms adapted to pick up and convey'the assemblages to be united, means for bringing previously pasted uniting bands into contact with the assemblages, a rotary member having slots adapted to embrace the assemblage partially as it is conveyed by the said carrier and thereby to wrap the uniting band around' part ofthe circumference of the assemblage, and means for subsequently completing the wrapping of the uniting band around the assemblage.
