This invention relates to a paper pull-"for cigarette machines, its main object bemg to ull the paper through the rod-forming through the forming mechanism after abreak of the paper, thepull being continued until the rod has acquired sufficient strength 0 to automatically break and jump the gap to the" cutoff mechanism. v

v In the operation'of'continuous rod cigarette machines heretofore, the leading end of the paper or wrapper-strip hasbeen pulled through the rod-forming mechanism by hand. Immediately. after the machine is started,zthe rod is soft be'causethere is insuificient tobacco encased in the wrapper to give it proper density. Moreover, pulling it the wrapper-strip through the forming mechanism by hand, doesnot gi'veit the same speed as that of the rodforming tape,- so that the irregularity of pull frequency results in wastage of the paper and tobacco i filler therefor.

The present device overcomes this difli culty and generally speaking consists of a roller which is pressed against the tape-wheel ofthe machine by a spring, the tape-wheel driving the forming tape which guides the wrapper through the rod-forming mechanism of the machine. The leading end of the wrapper-strip, after having been led by hand through the printer, past the tobacco feed,

' 5 the rod-forming mechanisms, the paster and the sealer, is clamped against the tape-wheel by the roller, and is thus pulledthrough the machine atithe same speed as the tape, after themachineis started. When theportion of. the wrapper-strip which'is completely filled with tobacco and formed into arod of the j proper strength, arrives at thetape-wheel and under the paper pulling roller, the cur-V vature of the wheel causes the rod to break,

5 whereupon the free end of the same, which is held straight by its own stiffness, automati- V cally jumps the gap into the bell-mouth of the cutoff mechanism. Thepaper puller,no longer-required, is thrown out of engageu t with the tape-wheel and held in inoperative position during normal operation of the machine.

Fig. 1, showing the'newiy formed cigarette rod being pulled over the tape-wheel the moment, when havin" reached its proper strength, it automatic-a"; breaks andjumps the gap toithc cutoff; Fig. 3 is a front elevation of a part-of the tape wheel and the roller showing the empty paper being pulled over the wheel by the action of the roller; and Fig. t is a front eievation of a part oithe tape-wheel-showing the free end of the formed cigarette rod jumping the gap to'the bell-mouth of the cutoff, a'l'ter having been broken off as shown a B in 2. q In carrying the invcntioninto effect, there is provided the rod-forming mechanism of a 7 and jump the gap to the cutoff. In the best constructions; contemplated, there is also provided means tor-holding the pulling means out of action during normal operation of the machinaand the pullingimeans coactsiwith the tape-driving wheel of the rod-forming mechanism of the cigarette machine. The parts above mentioned maybe varied con- V i 1 structlon withinthe scope of the claims, for

the specific devices-ciected to illustrate the V invention is but one of numerous concrete .embodlments-of the same. The invention, therefore, is not to be restricted to the precise details of the specific structure shown and described. f V

Referring to Figs. 1 and 2, P indicates the end of a newly started wrapper-stripwhich has been manuallyied through the printer,

. 4 i n the tobacco feed, the rod former, the pastel and the rod sealer, and has finally been led over the tape-wheel 5 which drives the endless rod-forming tape 6, upon which the paper P rests as it comes from the tobacco feed of the machine. The tape 6 runs in the customary manner over a. number of idlers T1 of which only one isshown. Shaft 8 carrying the wheel 5 and the studs 9 of the idler 7 ar carried by the frame 10 of the cigarette machine in the usual manner. The tape 6 is supported by the plate ll, attached by a bracket 12 to the frame 10 as usual.

After the paper P has been led over the tape-wheel 5, it is pressed against the same by a-rubber covered roller 13, which is mounted by means of a stud i l on a movable arm 15, which swings on a stud 16 hold in a bracket 1'? carried by the frame 10. it torsion spring 18 connects the arm 15 with the projecting lug 17 of the bracket li'and nor mally holds the roller 13 against the tapewheel 5.

When the machine is now into operation, the rotation of the wheel 5 pulls the paper through the machine as shown in Fi 3, the paper being filled it passes under t: tobacco feed, not shown, and formel into a cigarette C, as it travels through the rodforming mechanism of the machine. As the finished rod C emerges from the well known sealer 19, which is turnable on a pintle 20 by a handle 21, and when in operation presses rod C against the plate 11, the strength of the rod causes it to break as shown in B in Fig. The free end of'rod C, wl i is now driven by the pressure of the tape'6 in the rod-forming mechanism, then jumps the gap and enters the bell-mouth 22 of the cutoff m chanism as shown in Fig. 4. The bellmouth 22 is connected by an arm 23 with a cutoff mechanism which divides the and G into individual ci arettes.

The cigarette rod now beingdriven without the aid of the roller 13, the latter is moved into the inoperative position shown by dotted lines in Fig. 2, in which a slot25 in the hub of the arm 15 registers with a pin 26 of the stud 16 and is pushedinto engagement with it by a spring 27 in the hub of the arm 15.

To again put the roller 13 into action, the arm 15 is pulled outwardly untilthe slot'25 is disengaged from the pin 26. The torsion spring 18 will then force the roller-against the wrapper-strip on the wheel 5.
