(01. 93-6) The present invention relates to the packing of the folding fingers showing the adhesive apof cigars, by mechanical means, in individual plying devices, and coverings of tissue paper, cellophane or the like.

The roller 25' of the rocking Fig. 9 is a partial side view of the construction lever co-operates with a cam 26. As soon as a of Fig. 8. covering has arrived in front of the ram 22, the 0 Figure 9a is a continuation of the showing in latter is'thrust by the cam 26 into the covering, Figure 9, whereby the cigar arrives in the position shown Figure 10 is an enlarged lateral elevation of in Figs. 13. During this process, the coverings the perforating device, are prevented from slipping by astop-bar 27 65 Figure 11 is an enlarged partial side elevation which co-operates with the grooved drum 21.

After the cigar has been brought into the middie of the covering, it is first brought into the range of a finger 28 operating radially tothe drum 21, which finger firstrof all folds the end of the covering in the manner shown in Fig. 4. After, a further movement of the drum, the end of the covering arrives in front of a foldingfinger 29 "which performs a further folding. Then the end of the covering passes into the range of a further folding-finger 30, which folds another piece of the end of the covering. The end of the covering is then finally folded by means of the finger 31, after the drum has made another turn in the direction indicated by the arrow in Fig. 4. While the, ends of the coverings containing the cigars are closed by the folding fingers 28-30, they are held by the rails 32- which are arranged parallel to the peripheryin such manner that the covering cannot turn in the grooves 21.

Fig. 44 is intended to illustrate the means for driving .-the folding fingers 2831. The folding finger 28 is mounted on a bolt 71 attached at '70 to the frame of the machine. To the finger 28 there is connected" the lever '72 at the end of which a toothed quadrant '73 is provided.- The toothed quadrant engages with a rack 74 which is mounted in suitable recesses '75 of the machine casing '76. On the rack '74 a lever '78 engages by way of a link member 7'7, which is swivelled by actuating members not shown in such manner that the rack is drawn downwards at the right moment into the position shown in Fig. 4. The folding finger 29 is mounted at 79 on the machine casing '76 and carries a toothed quadrant 80 whichengag'es'with' the rack '74 by means of a spur wheel 82 mounted on the machine frame at 81. The foldingfinger 30 is mounted at 83 on the machine frame and also carries a toothed quadrant 84 which engages with the rack '74. The

folding finger 31 is mounted at 85 on the machine 'casing and also engages, with therack '74 by means of a toothed quadrant 86 with which it is provided.

Thus, when the rack "74, actuated by the lever '78, passes into the position indicated by dotted .lines in Fig. 4a, the folding fingers 28-31 are swungback whereupon the drum 21 can make a further movement, 'and the folding fingers 28-31 can again come into operation.

It is obvious that before the fingers 28-30 come into contact with the ends of the covering, they can be caused to pass over a device which supplies glue, so that adhesion is effected simultaneously with the folding operation. For each finger there is provided a cement applying roller 100 which is connected to an adhesive receptacle 101. When the fingers 28, 29, 80 and 81 swing out they make contact with the corresponding adhesive devices and take of! a 'hin layer of adhesive which they give off when folding the corresponding fiaps. Only certain of these adhesive applying devices are shown in the drawings, but the remainder are similar in construction.

The folding fingers 28-81, can, however, also be arranged advantageously only on one side of the drum, while on the other side of the drum the apparatus'for closing the end of the covering facing the tip of the cigar, shown in Figs. -'7, is arranged. Figs. 5 and 8 show a longitudinal section of this apparatus in various operative positions. Fig. '7 shows a partial view of the apparatus shown in Fig. 8, as seen from the left. This displaced longitudinally in relation to the end of the covering which is opposite the folding'finger 28. On the sleeve 33 a further sleeve 34 is mounted, the conical end 84 of which engages under the rear ends of the pivoted levers 35. The pivoted levers 35 are articulated at 36 to the sleeve 38 and their front ends 85 engage in the holes 3'7 of the cheeks 38. While the folding finger 28 closes the end of the covering in the manner shown in Fig. 4, the sleeve 33 is thrust onto the other end of the covering in such manher that the cheeks 38 assume the position shown in Fig. 5. By meansof a controlled lever 40 engaging in the annular groove 89, the sleeve is displaced in such manner that the cheeks arrive in the position shown in Fig. 6. As the sleeve 33 is mounted on a continually rotating spindle, the end of the covering is twisted together in the manner shown in Fig. 6. It is obvious that if the rotating sleeve is not so arranged, that it moves with the grooved drum- 21, it must perform this operation in the same time that is required by one of the folding fingers to complete its folding operation.

Further it is immaterial whether the rotating sleeve shown in Figs; 5-7 performs its function simultaneously with one of the folding. fingers 28-80 orif the twisting together of the end of the covering takes place before or after this operation.

Under the grooved drum 21 there may be arranged advantageously a conveyer belt 42 running over the. rollers 41, which belt passes the cigars, covered in the manner just described, to the position where they can be further dealt with (packing position).

In the mode of construction shown in Figs.v 8 and 9 the grooved drum 21 is not provided with folding devices for folding the ends of the cover-' two pairs of rollers 44 and 45, which squeeze the two ends of the covering together. 'The end of the covering facing the tip of the cigar is now conducted to a perforating device 46; The vertically reciprocating punch 4'7 ,cooperates with a suitably formed matrix 48 which serves as a bearing or support for the squeezed-together ends of the sheath. The punch 4'7 thereby carries aseries of punching dies 47' opposite which are corresponding openings in the matrix 48. The punch 47 is moved vertically in the guides 4'7.

which are provided on the frame portion 47 the matrix 47' is also secured to the frame portion 43. The punch 4'7 is provided with a slot 4'7 in which the crank pin 4'7 engages. The crank pin 47 is mounted on the crank (cam) disk47 which is mounted on the shaft 47". Also mounted on shaft 4'!" is the sprocket wheel 47' which is connected by means of the chain 47' with the sprocket chain mounted on the squeezing device 44. 45.

After two further movements of the conveyer belt, the. coverings arrive in the range of the device V, by means of which the ends of the covering are provided with the adhesive tabs. The adhesive tabs are made from the paper strip 49 coming from the bobbins 50. The pair of rollers 51, which are driven by the Geneva gearing 52, serve as tension members. Behind the pair of tension rollers 51 there are arranged the glue-applying rollers 58, which are connected with the glue-container 54. The rollers 55 serve as abutment for the rollers 53. As soon as the strips have arrived in the position shown particularly in Figs. 8 and 9, in which the ends rest on small tables 56'and the flattened ends of the covering rest thereon, the knives 57, which are pivoted on pins 58, are swung in the direction indicated by the arrow in Fig. 9. Thus the edges of the knives 57 meet with the edges of the knives '59, -so that a short portion is always separated from the strip 49. The pivoting movement of the knives '57 is produced by means of the spur wheels 60 which are oscillated by the crank mechanism '61, 62. With the spur wheels 60 there engage the toothed quadrants 63 which are connected with the axes 58 of the knives 57. Now

when the tabs have been severed, the knives,

swing further into the position indicated by dotted lines in Fig. 9, in which they place the previously severed ends of the tabs on the already adhering ends of the flattened end-portion of the covering. Then the knives swing back into their initial position, and the conveyer belt .43, after the tab-strips 49 have again been adcontinuously feeding a strip of flexible material,
