ABSTRACT:
A machine (10) is disclosed for processing an insulated wire (12), to sever the wire into a feed end (178) and an eject end (180), and to remove a selected portion of insulation from each of the ends. The machine (10) includes a wire cutting and stripping unit (22) including a left blade (64) having first and second spaced cutting edges (148, 154) associated therewith and a right blade (64') having third and fourth spaced cutting edges (148', 154') associated therewith. Additionally, a mechanism (60, 62, 126) is provided for moving the left and right blades (64, 64') in converging directions (170, 172) toward each other so that the first and third cutting edges (148, 148') effect the severing of the wire (12). After severing the wire, the left and right blades (64, 64') are further moved in the converging directions (170, 172) so that the first and fourth cutting edges (148, 154') move into insulation cutting engagement with the feed side end (178) and the second and third cutting edges (154, 148') move into insulation cutting engagement with the eject side end (180). As the two ends (178, 180) are withdrawn away from each other, the cut insulation slugs (194) are stripped off and collected by scrap collection tubes (186, 188).
