摘要

Apparatus for high-speed production of sets of accurately and identically sized insulated wire leads having wire terminals at the lead ends comprises: a feed mechanism including counter-reciprocating wire feed clamps for repeatedly drawing a plurality of separate strands of insulated wire simultaneously from a plurality of wire reels; a mechanism for simultaneously straightening and arranging the strands as they are drawn therethrough in parallel spaced apart relationship in a common generally horizontal plane; a severing mechanism for repeatedly severing sets of wire segments of predetermined length simultaneously from the strands; conveyor clamps for releasably gripping successive sets of wire segments received from the feed clamps; conveyor means for advancing the conveyor clamps so that the ends of the wire segments in the sets pass through processing mechanisms, and conveyor clamp actuator mechanisms for causing the conveyor clamps to initially grip sets of wire segments for conveyance and to subsequently release sets of the finished leads at a collecting station. The processing mechanisms include wire cutter and stripper mechanisms for accurately trim cutting both ends of the wire segments in the sets simultaneously and for stripping insulation therefrom simultaneously, and terminal attachment mechanisms for simultaneously attaching terminals to both ends of the wire segments in the sets. The apparatus further comprises a wire gathering mechanism for each processing mechanism for accurately guiding, positioning, and securing the ends of the sets of wire segments in the processing mechanism and for holding the segments against displacement during processing.
