Abstract: 279,432. M³ller, J. C. Oct. 20, 1926, [Convention date]. Cigar-making machines. - A method of manufacturing cigars consists in laying filling tobacco in a layer corresponding to the thickness and shape of a cigar upon a layer of overlapping cut tobacco leaves and covering with a second layer of cut leaves, cutting transverse strips from the continuous band so formed, rolling each strip into a filler, and delivering the filler to a travelling mould and thence to a wrapping table, to which wrappers are fed by endless bands. Paste is applied to the ends of the wrappers, the wrapping is effected by hand, and the cigars are placed with their heads in moulds on a conveyer band, removed to a second conveyer band which effects a re-rolling, and conveyed to a delivery band by a drum on which trimming is effected. In the machine shown, cut tobacco leaves Z are laid on an endless band 1 so as to overlap and are conveyed by a band 6 to a hand 10 moving over a table 12. A layer of tobacco is laid on the leaves from a container 13, levelled by a distributor 14, and compressed by resiliently mounted rollers 15, and an upper layer of tobacco leaves Z' is laid by endless bands 18, 22. The resulting band of tobacco passes through the channel 28 and transverse strips of the length of a cigar are severed by cutters 31, 32, each strip falling into a receiving trough 33 on a rotary drum 34. A cover pivoted to each trough 33 is closed to compress the tobacco into an approximately circular filler, which is carried around by the drum and dropped into a conveying trough 36, 37 on a lever 38 slotted to engage a crank-pin 43 on a rotating disc 44. The trough 36, 37 carries the filler down to a rolling apron 67, the member 37 of the trough being pivoted and opening to deposit the filler on the apron. When two rolling aprons are employed side by side, the trough 36, 37 receives alternate fillers from the drum 34, the remaining fillers being received by a pivoted device operated to carry each filler to one side and deposit it upon the second apron. The apron 67, Figs. 1 and 8, is secured at one end 66 to a table 63 and passes over rollers 68, 69 to a fixed point 70. The roller 68 is actuated by a connecting-rod 79 pivoted to a cam disc 77 and is guided by a slotted lever 73, an arm 75 on which is held by a spring 78 against the edge of the cam disc 77. The roller 69 is supported by slotted levers 83 on a shaft 84 rocked by means of an arm 85 in engagement with a cam 87. From the apron 67, the filler drops into a mould carried by travelling chains 96, Figs. 1 and 1f. Each mould, Figs. 12 and 13, comprises a pair of troughshaped members 91, 92 adapted to close on the middle of the filler, and tapering caps 114, 115 slidable laterally to engage the ends of the filler. The members 91, 92 are pivoted upon a bar 95 carried by the chains 96, and are opened and closed by links 110, 111 pivoted upon a shaft 106, which is mounted in a slotted member 105 on the bar 95 and is provided with rollers 107 running between guide rails. The caps 114, 115 slide on the bar 95 and carry rollers 118 held by springs 120 in contact with rails 119. After a long travel, the moulds are opened to drop the filler into guides 125, Fig. 1f, conveying them to wrapping tables 126 at the sides of the machine. Wrappers are fed by endless bands 127, which are moistened with water by a nozzle 127<1>. Adhesive is applied to the point of each wrapper 130, Fg. 15, by a roller 139 co-acting with a roller 132 in an adhesive receptacle 131. The roller 139 carried by an arm 140 pivoted at 141 upon a push bar 142, which is connected at 150 to a cam-actuated lever 148. The bar 142 carries a roller 143 travelling on a rail 144, a spring 146 holding the end 147 of the arm 140 against a stop 145 on the bar 142. The roller 139 runs over a spring-controlled plate 135 having an aperture 137 over. the cigar wrapper. When wrapped, the cigar is placed with the head end in a socket 155 on an endless band 156, from which it is transferred by rollers &c. to a band 163 moving over a table 167 and carrying the cigars under a table 168 by which they are re-rolled. The cigars fall into grooves 172 in a drum 171 and are trimmed by a rotary-disc knife 174 while passing under a guard plate 175. The finished cigars fall on a delivery band 173.
