Abstract

An apparatus is disclosed for trimming and or subdividing rod or other similar mill products at a coil forming station. The rod, which may have previously been formed into overlapping rings on a conveyor, is carried to the upper end of an upstanding cylindrical chamber overlying an axially aligned mandrel. The rings drop from the conveyor through the chamber onto the mandrel where they are collected in coil form. Separating fingers are movable into the chamber to temporarily interrupt the descent of rings therethrough, with the rings above the separating fingers being connected to the rings accumulated around the underlying mandrel by a single connecting strand. Pivotal arms, preferably sickle-shaped, are movable beneath the separating fingers across the path of ring descent. Each pivotal arm carries a shear blade which cooperates with a stationary shear blade located at the periphery of the path of ring descent. The connecting strand is carried by one of the aforesaid arms through a short distance to the periphery of the path of ring descent where the strand is cut by the cooperating shear blades.
