Abstract
Abstract Insulated wire stock is gripped at longitudinally spaced portions by a pair of clamp assemblies and cut in two by a wire and insulation cutting assembly between the clamp assemblies. The relatively adjacent ends of the cut wire are pulled apart by the clamp assemblies so as to strip the cut insulation therefrom and bring the stripped wire ends beyond a pair of terminal crimping assemblies at opposite sides of the cutting assembly. Reverse movement of the clamp assemblies then brings the stripped wire ends into the crimping assemblies, and after terminals have been attached to the stripped wire ends, the stock and severed wire length are released and reverse movement of the clamp assemblies is continued to bring them back to their starting positions. A wire transfer mechanism and slotted bracket collect successively cut off wire lengths to which terminals have been attached. Brushes suppress whipping of the moving wire stock.
