Abstract: A bench model type wire stripper apparatus adapted to partially or completely strip a predetermined length of insulation or jacket layer from a conductor wire or cable, including clamping jaws operable to clamp a wire or cable in relatively fixed position while strip blades or strip and trim blades carried by a carriage are operated to trim the free end of the wire or cable and either partially or fully strip a predetermined length of the insulation or jacket layer from the wire or cable. Various features of the apparatus enable precise and efficient operation with stranded cable of relatively small gauge, such as 28-30 gauge wire, and facilitate stagger stripping of different conductors of the same conductor cord. Interchangeable blade holders enable remote set-up and quick interchange to accommodate various desired strip lengths.
