Abstract:
An apparatus for cutting off successive leading end portions of wire adapted to be advanced along a predetermined wire path running through a cutting station, the apparatus comprising:a wire cutter along the predetermined wire path adapted to cut wire; an electrical motor carried by the support having an output directly driving the wire cutter; a leading position sensor arranged in sensory communication with the wire cutter adapted to produce a signal indicating a first position of the wire cutter relative to the wire path; a trailing position sensor arranged in sensory communication with the wire cutter adapted to produce a signal indicating a second position of the wire cutter relative to the wire path different from the first position; an end position sensor arranged downstream of the cutting station, adapted to produce a signal indicating presence of wire in proximity to the end of the predetermined wire path; and a controller responsive to the position sensors to control electrical output to the electrical motor, selectively generating a first electrical output in response to the end position sensor to drive the motor and operate the wire cutter, a second electrical output to decelerate and slow the motor in response to the leading position sensor and a third electrical output in response to the trailing position sensor to substantially stop the motor and maintain the wire cutter adjacent to the predetermined wire path.
