  • Patent number: 4203335
    Abstract: A device for feeding a ribbon of sausage support loops into a clip attachment apparatus is attached to the clip attachment apparatus and includes a body member with a guide track for directing the ribbon of loops from a storage reel to the clip apparatus. A reciprocating piston operated drive pin engages the ribbon to incrementally drive the ribbon forward into position for attachment of a single loop to a sausage casing. A knife separates the single loop from the ribbon upon attachment of the loop to the sausage casing by the clip apparatus. Subsequently, the drive pin is disengaged from the ribbon and is reversibly driven into position for re-engagement and further advancement of the ribbon. The movement of the drive pin and knife is controlled by a cam track in the body member.
