Abstract

A clutchless wire cutting apparatus for successively cutting off leading end portions of a predetermined length of wire from a wire stock. The wire is advanced through a cutting station which includes the cutting apparatus. The cutting apparatus includes an electrical motor whose output is coupled to the cutter mechanism which performs the successive wire cuts. A proximity switch or sensor located downstream of the cutting station signals a controller each time the wire reaches the desired length to periodically generate an electrical current to the electrical motor for selectively intermittently driving the motor at a relatively high frequency corresponding to the frequency at which wire cuts are made. The motor may also be continuously driven for cutting shorter wire lengths. The motor has an output on an motor shaft which is coupled to a cutter shaft via a belt drive. The cutter shaft includes an eccentric cam which acts directly on the wire cutter. A proximity sensor or switch is also provided at the cutting station to determine the location of the wire cutter to provide a home position for the system.
