367,111. Packeting cigarettes. MOLINS, W. E., CHALMERS, J. W., JACKSON, D., and MOLINS MACHINE CO., Ltd., 2, Evelyn Street, Deptford, London. Jan. 9, 1931, No. 790. [Class 94 (i).] A machine which automatically packs at least two batches of cigarettes arranged side by side with adjacent batches each separated by a partition, into a box, comprises means for feeding adjacent batches of cigarettes to opposite sides of a partition automatically fed into the path of the cigarettes, and means operable to insert the separated batches of cigarettes, together with the partition, into a box. Foil feeding apparatus 13 cuts a rectangular blank of foil from a web and applies the blank, by rotary suckers, to a pocket 11, attached to and moved by an intermittently moving chain conveyer. The pockets are formed with central slots to accommodate a longitudinally blunt-topped knife 19, about which a descending tucker creases the foil. The edges of the foil are guided by guides 22, and the conveyer moves the creased foil beneath mechanism which sharply defines the creases. This consists of cam operated arms 23, 24 pivoted at 25, 26 with end plates 31 the foil being put under considerable tension by two depending spring plates carried by the arms 23, 24. The foil 18 is now as shown in Fig. 9, a central upstanding ridge 18a having been formed. The cigarettes are fed on to it, from opposite sides, from hoppers 33 fitted with vanes 34, by pushers 36 moved by chains 35. After the bottom layers have been fed-in at position A, a mechanism, fitted in duplicate, may be employed to deliver two strips of paper &c. on to the upper surface of each layer to act as separating strips. These strips may be cut from webs and moved into position by two contacting belts. The upper layers of cigarettes are fed in at position B, and on further movement of the pocket 11, the edges 18b of the foil are folded over by folders 39, 40 to present a partially wrapped assembly, Fig. 12. Cam-operated presser plates, not shown, may be employed at the cigarette filling station to ensure that the cigarettes are pressed truly into the foil-lined pocket. A plunger 47 ejects the partially-wrapped assembly into a pocket 48 of a rotary turntable 49 from which it is ejected by a plunger 62, operatively connected to the plunger 47, on to a plate 60, which carries a blank of foil 64, Fig. 13, cut from a web and applied to the plate by a suction roller. Closed boxes 51, contained in a magazine 52, are fed along by an intermittently moving chain to a suction device 55, 56 which turns back the lid of the box, ready to receive the charge, which is pressed through an aperture 61, in the plate 60, by a cam-operated presser 65. As the box is again moved forward the edge of the plate 60 folds back the edge 64a, Fig. 14, on to the assembly, the other edge 64b being folded back into the lid. The box is now moved by a conveyer 72 past a folder 73 which closes the lid, the completed box being discharged on to a table. Specification 359,088 is referred to.
