Definitions

  • This invention concerns improvements in or other moving, between which the crepe strip is 3 fed by a sidewise movement, and pushing the resulting stub by a pusher through a spoon into a tube of cigarette paper.
  • the lengths of stub material are long enough for six individual stubs; If then a pressed stub of such length and made in the above-mentioned manner is to beinserted into :a paper tube so as to fill the tube along its whole length, the production would be-much too slow andthe stubs not perfect in shape, owing to the fact that the cut piece of crepe paper has to be moved by a sideways or lateral movement into the pressing chamber. in this manner loses its true rectangular shape or its correct position and the result is that the stubs are not of a proper cylindrical shape. 7
  • a machine for making stubs for cigarettes compristhe paper may be fed into the slot at one position i of the member and after a predetermined rotary movement of the member thepresser may move into said slot to press the paper into a stub.
  • the member may be in the form of a rotatable drum and be provided with a number of. slots so that Usually The wide piece of crepe paper moved paper may be fed-into and pressed, in each slot in turn.
  • the drum may be rotatable intermittently. Where adrum is employed it may rotate on a fixed shaft which isslotted transversely to its axis said slot comprising a fixed presser member with a suitably shaped end so disposed that a pressed stub is coaxial with the shaft.
  • a stub ejected from themember or'drum may pass through a spoon into a paper tube in the known manner said tube being held on the spoon by aclampin'g device which is relaxed towards the end of the movement whereafter the tube is stripped from the spoon by the continued movement of the stu-b.
  • - Stubs'encased by a paper tube in this manner may be conveyed to a trim-v ming device where the ends are trimmed by knives to reduce the stubs to the proper length with square neat ends.
  • Figure 1 is a plan of the whole machine excluding the crepe feeding reel and trimming device.
  • Figure 2- is an enlarged view of the middle of Figure l, where the most important parts are situated.
  • Figure 3 is a section of Figure 2 on the line III--III.
  • Figure 4 is a section on line IV-IV Figure -'2 showing a few parts.
  • Figure 5 is a side elevation of a reel feeding and trimming device.
  • a web of crepe paper or the like i Figure 3 is fed from a reel 2.
  • Figure 5 by serrated or knurled feed rollers 3 and 4 towards a drum 5;
  • the web passes over a sloping guide plate 6.
  • a piece of crepe of the required length is cut by a cutting device, comprising a fixed blade I and a rotating blade 8, the cut taking place when the leading end of the web has been fed by further feed rollers 9 and I0 into a'slot H in the drum 5.
  • the crepe passes over a guide plate I2 during the feeding movement.
  • the drum 5 rotates intermittently so that each of its ten slots is presented in turn to the crepe feeding position.
  • the drum is supported on a rotatable sleeve l3 to which is fixed a wormwheel l4.
  • Beneath the wormwheel is a worm which has a thread consisting partly of a helix and partly of portion of zero lead.
  • This wormdevice is well known and as the worm rotates the drum is moved when the helical part of the thread is engaging the wormwheel and is, stationary when the portion 3 of the thread which has zero lead is passing through the teeth of the wormwheel
  • a fixed shaft l6 which, as shown in Figure 3, has a slot H in it of the same width as a drum slot and disposed 189 from the crepe feeding position.
  • 8 is provided which enters a drum slot II when the latter is in alignment with the slot in the fixed shaft [6.
  • the inner end of the presser plate has a concave groove in it, see Figure 3, so that when the plate has moved into the fixed shaft to its final position a circular hole is formed of a diameter equal to that of a finished stub. It will be seen then that a piece of crepe fed into the drum slot is eventually squeezed by the presser plate into a stub.
  • a pusher rod l9 pushes the formed stub axially through a spoon 28 into a paper tube, for example of cigarette paper, which is brought on to the outside of the spoon and held firmly in position during the pushing operation by a cam operated pad 2
  • a paper tube for example of cigarette paper
  • which grips the tube by pressing it against the wall of the spoon.
  • the paper tubes are formed in the usual way from a web 22 by means of a former or mandrel 23 fitted with appropriate known means for folding and closing a web of paper to a round shape and securing the seam by glue or by crimping.
  • the seam is made by crimping between a female crimping wheel 24 and a small male crimping wheel (not shown) but which is held inside the paper tube 25 in the usual manner.
  • the endless formed tube 25 is cut by a scissors device 26 into the required lengths. As soon as a tube of cigarette length is cut, from the endless tube it is pushed aside, that is out of line with the endless tube by a cam operated device 21 and brought into alignment with the spoon 20.
  • Another pusher 28 in alignment with the spoon then pushes the cigarette tube endwise on the spoon and the previously mentioned clamping pad 2
  • the clamping pad then lifts to release the tube and as the stub is still being ejected by the rod l9 and the paper tube is now freed, the stub takes the tube with it until both components are clear of the spoon.
  • Figure 4 shows the arrangement of the parts 27 and 29.
  • a completed stub is pushed along until it falls down the plate 30 and simultaneously a fresh tube is brought into alignment with the spoon.
  • -29 is lifted by a cam as explained later and returns until the part 21 is again in line with the paper tube 25 when it drops to receive the next tube.
  • the machine has two cam shafts 40 and 4
  • the shafts are geared together by bevel gear wheels 42 and 43.
  • On the shaft 40 is a cam 44 which reciprocates the stub pusher rod l9 through a suitable lever.
  • a spiral gear wheel 45 At the end of the shaft 40 is a spiral gear wheel 45 which drives a similar wheel 48 fixed to a shaft 41 at the other end of which is fixed a roller 48 which drives the conveyor 3
  • a large gear wheel 49 drives a small one I49 on a shaft 5
  • This wormwheel is fixed on a shaft 53 on which the feed rollers 4 are carried and a gear wheel on it (not shown) drives an equal gear wheel 54 on a shaft 55 to which the feed rollers 3 are fixed.
  • At one end of the shaft 50 is a spiral gear wheel 56 which engages a similar wheel 51 fixed to a shaft 58 which carries the feed rollers ID.
  • a gear wheel (not shown) engages with an equal gear wheel 59 on the shaft which carries the feed rollers 9.
  • the worm which drives the wheel I4 is driven from the shaft 4
  • a cam 84 which reciprocates the presser l8 through a suitable lever which engages an extension 65 of the presser, slidable in a guide 86.

  • the rod is guided at 11 and at its forward end has two pins, one of which marked 18 is shown.
  • These rods in conjunction with a spring (not shown) oscillate the blades of the scissors 26 about a pivot 19 to effect cutting of the paper tube 25 in the known manner.
  • the scissors pivot 19 is fixed on a block 80 which slides to and fro on a guide 8
  • the tube is supported in a guide 84 which as shown, is stationary, though it may be attached to the block 80 so as to move with the scissors.
  • the tube pusher 28 is loosely pivoted at 85 to an arm 86 of a bellcrank lever pivoted at 81.
  • the other arm 88 of the lever has a roller 89 which engages with a cam 90.
