ABSTRACT:
Apparatus comprises a clamp to fix flat cable against axial movement relative to a strip slide plate which is moved rearward relative to stripping blades by a pneumatic cylinder. This strips insulative jacket from free end of cable engaged by blades to expose foil shield. Another pneumatic cylinder causes blades to retreat from path of cable, and another pneumatic cylinder advances stripped end so that edges thereof closely enter mutually facing arcuate channels in laterally spaced guides. Channels have respective first portions profiled to receive edges of the jacket closely therein, second portions profiled to receive edges of the exposed shield therein, and respective shoulders between each first and second portion. A pair of opposed rotary cutting blades extend through slots in respective channels so that arcs of blades are initially exposed only in second portions of channels. Further advance of cable after jacket abuts shoulders moves guides relative to blades until arcs extend into first portions to cut shield to jacket.
