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 to be driven to cut the wire during the stoppage of the wire supply and to be 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. Front and rear insulation rotating bars are driven to contact the insulation forward and rearward of the wire cutting position and to move in the opposite directions to rotate the insulation thereof while the wire portions at the opposite sides of the wire cutting position are forcibly drawn in the directions away from the wire cutting position. Recesses of a suitable size are provided on the inner side surfaces of the wire cutting blades at a position slightly spaced from the edge thereof, and paired insulation stripping blades are adapted such that one member of each pair facing the recess of the wire cutting blade is retracted while the other is extended with respect to the wire cutting blades, whereby the end portions of the insulated wire, as cut, exte…
