ABSTRACT:
A packaging machine applies clips to rope sections of filled tubular casing to form clubs. In such a machine, a new clipping mechanism includes a piston-in-piston structure. Clip jaws are linked to the external piston to be driven by that piston. A punch is affixed to the internal piston. The punch is driven partially by the external piston as the internal piston "rides along", and partially by the internal piston. The punch is guided, in part, by punch guides present in the clip jaws, when closed. Also in the packaging machine, a cut-off knife is driven, and voider plates are driven in part by non-cylindrical and therefore consistently aligned pistons in non-cylindrical cylinders.
