Abstract: 423,367. Making and filling cartons. CHALMERS, J. W., HORGAN, G. D., and MOLINS MACHINE CO., Ltd., 2, Evelyn Street, Deptford, London. July 31, 1933, No. 21453. [Classes 18 and 94 (i)] Relates to apparatus for making or making and filling containers of the type described in Specification 386,577. The blank from which the container is formed is shown in Fig. 5, and the container in its open and closed positions respectively in Figs. 10 and 11, transition from one position to the other being effected by sliding the sleeve 12, 14 on the packet. Each blank comprises main panels 4, 5, a narrow panel to form the base, side rings 7, and parts 11-14 to form the sleeves connected to the panels 4, 5 by strips 9, 10 provided with transverse lines of scoring as shown. The blanks are fed from a stack 1, Fig. 1, in a direction transverse to their length, between cutting and scoring rollers 3, to a position 15 at which the side wings 7, 13, 14 are folded upwards. The blank is then fed at right angles to its previous travel by rollers 16 and belts 17 past devices 171 which flatten out the wings 13, 14 and the wings 7 on the panel 5. The wings 7 on the panel 5 remain upstanding and are engaged by a conveyer piece 19 and a catch thereon, (not shown), which move it through folders 20 whereby the sleeve parts 11, 12 and one half of each of the strips 9, 10 are turned under against their respective panels 4, 5. A batch of cigarettes is fed from a hopper 21 by a conveyer to a position 24, from which they are subsequently thrust by the next succeeding batch on to the panel 4 of the blank between the upstanding wings 7. As the charged blank commences its next intermittent movement along the table 18, the batch at position 24 is slightly retracted to prevent fouling the ends of the cigarettes. The parts 5, 6, 10, 12 are next turned over by folders 27, 28 into the position shown in Fig. 7, and the partly completed packet is delivered on to a bed 29 in front of a pusher piece 30. It is then moved at right angles and the side wings 13 are folded up by blades 31. Adhesive is applied by wheels 32 to the undersides of the wings 7 on panels 5, which are now, together with the parts 14, turned down by folders 34 into the position shown in Fig. 9. Sectors 35 apply adhesive to the parts 14 and blades 36 turn up the part 13 to adhere thereto, the packet, now as shown in Fig. 10, being delivered into a heated stacker 37. A plunger 39 pushes the topmost packet of the stack on to a table 40, Figs. 1 and 4, where it is gripped by a presser 41 and plate 42. Arms 43 move forwardly and inwardly to engage the rear edges of the sleeve and push them forward so that the strips 9, 10 are folded together to close the packet as shown in Fig. 11. The packets pass away between guides 46. In a modified form of machine, the blanks are pre-cut and scored and are moved by a suction member 48, Fig. 13, to a table 51 over which they are moved by rollers 49, 50, 53 against a stop 55. Folders 56, 57 turn the parts 11, 12 and half the strips 9, 10 underneath during this travel. A plunger 58 descends and presses the blank into a pocket 59 in an intermittently moving conveyer 60. The sides of the channel 54, through which the blank moves, turn up the wings 7 of the panel 4 and the side wings 13 while the panel 5 and its associated parts are turned into a vertical position by a guide. A charge of cigarettes is introduced and the partially formed packet is now as shown in Fig. 16. The packet is fed at right angles past folding and adhesive applying stations which result in the intermediate condition shown in Fig. 18, and, finally, in a packet similar to that shown in Fig. 10, which may be moved into a stacker and closed in the manner described above. In another form of apparatus, the parts 11-14 are left unfolded until the stage shown in Fig. 28 is reached. The packet is fed, by conveying means such as is described in Specification 396,492, past devices for folding the side wings 7, and into a pocket in a turret 80, Fig. 21, which turns through 90‹ while folders 81 turn back the parts 11-14 into the position shown in Fig. 29. The packet is completed by means similar to those described above. In a further modification, the packets are mainly formed before the introduction of the cigarettes takes place. The blanks are fed from a magazine 89, Fig. 31, on to a table 92 by rollers 90, 91, adhesive being meanwhile applied. A plunger 93 forces the blank through folding mechanism 94, 95, of the kind described in Specification 1116/11, [Class 94 (ii)], which forms the blank into the packet shown in Fig. 28. In this form it is stripped from the plunger and forced by a plate 96 into a heated stacker 97 from which they fall on their sides in a further stacker 98. A mouthpiece is caused to enter the packet and a plunger 102 delivers a batch of cigarettes through it. The sleeve members are folded and secured by means of folding and adhesive applying mechanism arranged in two series at right angles. In this form of apparatus, the filling devices may be omitted and the packets filled manually. In any of the above forms of apparatus, the batch of cigarettes may be enveloped partly or wholly in a foil &c. wrapper, for instance, as described with reference to Figs. 35 and 36, (not shown).
