  • Patent number: 4838129
    Abstract: Wire stripping apparatus for automatically stripping insulation off a wire core, comprises:(a) a guide forming at least one opening to receive an insulated wire end,(b) at least one wire end sensor for sensing a wire end inserted through that opening, or a selected opening of a group,(c) wire end clamping structure operable in response to said sensing to clamp the insulated wire inserted through said opening,(d) cutter structure operable in response to said sensing to sever a predetermined length of insulation on the insulated wire end inserted through the opening,(e) and carriage structure carrying the sensor and the cutter structure to retract same relatively away from said clamp structure after it has clamped the wire end and after the cutter structure has severed the insulation, thereby to pull a selected length of insulation off the wire core.
