Apparatus for cutting an insulated wire, stripping the end thereof and twisting the wire strands

An apparatus for cutting an insulated wire, stripping the end thereof and twisting the wire strands, comprising;

• means for intermittently supplying said insulated wire,
• wire cutting means adapted to be driven toward said supplied wire to cut the same at a predetermined position during the stoppage of supplying operation of said wire supplying means,
• front and rear insulation cutting means adapted to be driven toward said wire to cut substantially only the insulation of said wire at positions spaced apart from said predetermined cutting position of said wire cutting means,
• said front and rear insulation cutting means being located away from each other with respect to the axis of said supplied wire, whereby the end portions of the wire at the opposite sides of said wire cutting means are placed in spaced relation with each other, when said wire cutting means and said front and rear insulation cutting means have been driven toward said supplied wire,
• said wire cutting means having recesses formed on the surfaces thereof at the area around the position where the tip ends of said wire at the opposite sides of said wire cutting means abut against said surfaces of said wire cutting means, when said wire cutting means and said front and rear insulation cutting means have been driven toward said supplied wire,
• front and rear insulation rotating means adapted to be driven during the stoppage of the supplying operation of said wire supplying means, said front insulation rotating means being located between said front insulation cutting means and said wire cutting means, said rear insulation rotating means being located between said rear insulation cutting means and said wire cutting means for rotating the insulation of said end portions of the cut wire at the opposite sides of said wire cutting means about the axis of said wire,
• means for drawing said wires disposed forwardly and rearwardly of said wire cutting means in the directions away from said wire cutting means while said insulation rotating means are rotating the insulation of said end portions of the cut wire at the opposite sides of said cutting means, whereby the insulation of said end portions of the wire at the opposite sides of said wire cutting means is stripped from said wire, while the portion of the wire strands stripped of the insulation is twisted by the rotation of said portions of insulation being stripped, with the tips ends of the wire facing said recesses of said wire cutting means.
