Abstract

A twister assembly for use in connection with bundling one or more objects with a length of wire may cut, grip, eject, and twist the length of wire. The twister assembly includes a main shaft driven by a main shaft motor and a twister shaft driven by a twister motor. The main shaft may be operatively coupled to a gripping mechanism, which is operable between an open and a closed position, a cutting mechanism, and an ejector mechanism. The twister shaft may be operatively coupled to a twisting mechanism, where the twisting mechanism includes a plurality of gears configured to rotate a twister pinion. The twister pinion is further configured to engage the length of wire and twist a portion of the length of wire to form a knot. Related twister assemblies and methods are also provided.
