  • Patent number: 5644896
    Abstract: An improved packaging device designed for the filling of flexible, tubular casing and for the sealing of the casing in discreet lengths which may then be further processed or packaged. The device includes a mounting assembly having a floor mounted frame with a rotatable platform supported by the frame. Adjacent the frame and platform is a device for feeding product through a product horn into casing which is shirred on the horn. The platform includes a plurality of specially designed clippers arranged in a circular array. As filled casing is discharged from the feeding mechanism it is directed tangentially into the circular array of rotating clippers which are equally spaced from each other. The clippers sequentially operate to gather the casing, apply spaced, double clips to the casing, sever the connection between adjacent clips, and to then discharge the packaged link from the device.

  • Patent number: 5085036
    Abstract: Apparatus for the high speed manufacture of elongated tubular film products from lengths of flexible, flat films. Film is unspooled passed over a forming collar, and onto a tube. On the tube, the film has a circular cross-section, with overlapped edges. A sizing ring correctly sizes the overlap. The film is immediately fed into a heating unit, where a closed-loop band contacts the overlap and heats the film to form a sealed seam. The film is advanced through the heating unit by boggie mounted drive belts. From the heating unit, the film is advanced into accumulation adjacent a casing brake.
