ABSTRACT:
An apparatus for cutting an insulated wire, stripping the end thereof and twisting the wire strands, comprises an insulated wire intermittent supply, cutting blades driven to cut the wire during the stoppage of the wire supply and returned immediately thereafter. Front and rear stripping blades are driven to cut only the insulation of the wire at positions spaced forwardly and rearwardly of the wire cutting position and returned after a predetermined period after return of the cutting blades. A pair of front insulation rotating bars are driven to contact the insulation rearward of the front insulation cutting position and moved in the opposite directions to rotate the insulation thereof while the cut wire length is forcibly moved in the supply direction thereof, whereby the end of the cut wire length is stripped and the strands thereof are twisted. A pair of rear insulation rotating bars is driven to contact the insulation forward of the rearward insulation cutting position and moved in the opposite directions to rotate the insulation thereof while the supplied wire is forcibly moved in the direction opposite to the supply direction thereof, whereby the end of the wire is stripped and the strands thereof are twisted.
