  • Patent number: 5054257
    Abstract: A strip cutoff assembly for successively partitioning an array of can-type containers connected by a continuous plastic strip as the array travels along a conveyor at a constant rate. The strip cutoff assembly includes a pair of endless chains carrying a cutting device in an orbit about a series of axles for periodically dividing the array into units of a predetermined length. An alignment device connected to the cutting device contacts the containers so as to evenly space the containers as the cutting device traverses the plastic strip.

  • Patent number: 4817361
    Abstract: An apparatus for installing a plastic carrier onto a plurality of side-by-side cans includes a pair of canted discs arranged for rotation around non-coincident intersecting axes. A number of shoes around the periphery of each disc, engage opposite edges of the carrier and expand the carrier as the discs rotate, while a conveyor moves the side-by-side cans into registry with the expanded carrier. A rolling depressor, between the discs, presses downwardly on the expanded carrier, urging the carrier away from the shoes and onto the cans.
