  • Patent number: 5491961
    Abstract: A package banding machine for wrapping each of plural packages with a band. The machine includes a package conveyor for continuously moving successive packages in-line in a machine direction at a set line speed. A series of band transfer heads connected to a transfer head conveyor are provided for transferring separate package bands from a supply source into overlying proximity with each package's obverse face, the transfer head conveyor also moving at the set line speed. A band forming head is cooperatively associated with the band transfer head, the forming head functioning to deform each band around against opposed side faces of a package after the transfer head has positioned the band against the package's obverse face.

  • Patent number: 4931131
    Abstract: A package collator machine adapted to translate two successive in-line packages into face-to-face paired orientation, particularly where the faces of those packages present plural curved surfaces, e.g., shrink wrapped sausages. The machine includes first and second package conveyors, one having a transfer section of a lesser length and the other having a transfer section of a greater length, that are juxtaposed to define common entry and exit points. The difference between the lesser and greater conveyor lengths is at least equal to the length of the trailing package of each package pair. A series of active package seats is preferably connected with one of the first and second conveyors, and a series of inactive package seats is connected with the other of those conveyors.
