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.

Apparatus for stripping a coaxial outer layer of insulation or jacket material from an electrical conductor wire or cable comprising, in combination:
- a base defining a longitudinal axis,
- clamping means including a pair of clamping jaws supported by said base and operable between relative open positions enabling positioning of a conductor wire therebetween and closed positions clamping said conductor wire therebetween,
- carriage means supported by said base for movement along a predetermined path of travel,
- stripper means carried by said carriage means and including a pair of mutually cooperable stripping blades, blade holder means supporting said stripper blades for movement between relative open positions adapted to receive said conductor wire therebetween and closed positions adapted to sever the coaxial layer a predetermined radial depth,
- actuator means supported by said base and cooperative with said carriage means to effect selective movement of said stripping blades when in their said closed positions to sever the insulation layer of the conductor wire disposed therebetween and move said severed insulation layer longitudinally of said conductor wire,
- and stop means carried by said actuator means and defining a reference surface against which an end of the conductor wire may be placed preparatory to trimming and stripping thereof,
- said actuator means including means adapted to effect pre-travel of said stop means prior to movement of said carriage means in a direction to move said severed insulation layer so as to effect release of any severed insulation slugs lodged between said stripper blades and said stop means.
Apparatus for stripping a coaxial outer layer of insulation or jacket material from an electrical conductor wire or cable, comprising, in combination:
- a base defining a longitudinal axis,
- a first pair of parallel bearing rods supported by said base in transverse relation thereto,
- clamping means including a clamp holder block slidably mounted on said first pair of bearing rods through ball bushings, a pair of clamping jaws one of which is mounted on said base and the other of which is mounted on said clamp holder block for movement between open and closed positions relative to said one of said clamping jaws,
- a second pair of bearing rods supported by said base in substantially coplanar relation parallel to the longitudinal axis of said base,
- carriage means slidably supported on said second pair of bearing rods through ball bushings for movement along said second bearing rods,
- stripper means carried by said carriage means and including a third pair of parallel bearing rods disposed transverse to the longitudinal axis of said base, a first blade holder block supported on said third pair of bearing rods through ball bushings for sliding movement therealong, a second blade holder block fixedly supported on said carriage means in lateral relation to said first blade holder block, a first set of stripping and trim blades mounted on said first blade holder block for movement therewith, a second set of stripping and trim blades mounted on said second blade holder block so as to lie in laterally opposed relation with said first set of stripping and trim blades, said first and second sets of stripping and trim blades being movable between relative open positions adapted to receive a conductor wire therebetween and closed positions wherein said stripping blades slit the coaxial outer layer a predetermined radial depth and said trim blades effect complete severing of the conductor wire,
- actuator means supported by said base and cooperative with said carriage means to effect selective movement of said stripping blades when in their said closed positions as as to sever the coaxial outer layer and move the severed layer longitudinally of said conductor wire,
- and stop means carried by said actuator means and defining a reference surface spaced a predetermined distance from said trim blades and against which an end of the conductor wire may be placed preparatory to trimming and stripping thereof,
- said actuator means including means interposed between said actuator means and said carriage means and adapted to effect pre-travel of said stop means prior to movement of said carriage means in a direction to remove the severed coaxial outer layer so as to effect release of any severed slugs lodged between said trim blades and said stop means.
