1,130,752. Cigarette making machine. MOLINS ORGANISATION Ltd., and T. ROWLANDS. 15 Oct., 1965 [19 Oct., 1964], No. 42498/64. Heading A2C. Groups consisting of two cigarette lengths C1 and C2 and an interposed double filter element S, carried on a rotating drum 4, are abutted by actuated presser members 16 17, one, 17, of which is pivotly mounted on pistons 22, pivoting being effected by engagement of one arm of the member with a fixed cam 25 so that the presser is moved away from alignment with pick-up projections 5 on the drum 4 during entry of a group travelling axially in the direction of the arrow on a conveyer 1. The groups are picked up by projections 5 and held on the drum by arcuate guides, three of which, 9-11, are adjustable. The members 16 and 17 are slidable axially on the drum 4 and are mounted on pairs of pistons 19, 22 slidable in pairs of chambers 20, 23 respectively in the drum. Inward movement of the members 17 is limited by a stop 4a so that one end of the group is correctly algined for transference to a following connector strip rolling drum. The chambers at each end of the drum communicate with each other by conduits 43 and are connected to holes 39 in a carbon disc 34 through conduits 41 and holes 40. A part 29, fixed to the machine frame, has air entry and exit pipes 31 and 30 respectively which communicate with arcuate grooves 37 and 35 in the end face of a disc 32 which bears upon the carbon disc 34. During the pick up of the groups, the members 16 and 17 are forced outwardly by air entering the air chambers 20; 23 from the pipe 31 via the groove 37 and holes 41. During further rotation of the drum the holes 41 come into communication with the grooves 35, the chambers 20, 23 are exhausted and the members 16 and 17 press the elements of the group together immediately prior to transference to the connector strip rolling drum.
