Abstract

Pivotable clipper assemblies for attaching at least one closure clip to a product held in netting include a pivotable clipper mechanism having a clipper body configured to deliver clips to a clip window and attach the clips to netting and a first cutting cartridge mounted to the pivotable clipper mechanism. The first cutting cartridge includes: (a) a knife; (b) an actuation cylinder with a rod in communication with the knife that advances and retracts the knife; and (c) an anti-rotation block attached to a rear of the knife intermediate the knife and rod to inhibit the knife and rod from rotating, wherein, in operation, the first cutting cartridge pivots with the clipper mechanism.
