  • Device for forming and controlling the outer wrapping of packs in a cigarette packaging machine
    Patent number: 4738073
    Abstract: The device comprises an indexed conveyor wheel having a cylindrical surface with pockets, and a pair of photocell type transducers, one preceding the other in the direction of rotation of wheel, the first located in alignment with a station at which each pocket pauses as the wheel is indexed; one such transducer verifies the correct position of the outer wrapping in relation to the ends of the pack, whilst the other verifies correct position of the wrapping in relation to the sides. A knock-out interlocked to the transducers enables automatic rejection of those packs exhibiting defects in positioning of the outer wrapping.
