Abstract
Abstract A rotatable wire guiding assembly is provided which at one end receives a twisted wire pair fed thereto and at the other end fits with a grooved conical separator element that has a saddle shaped tip. Attached to the wire guiding assembly is a cutterstripper assembly which includes an insulation cutter and a set of plates that grip insulation for stripping. Actuators drive the wire cutting and stripping elements and a motor drives the rotatable wire guiding assembly and a pair of wire feed rollers.

Claim 1
Independent Claim
147 words
Apparatus for untwisting and stripping the ends of a twisted wire pair comprising: A. a rotatable assembly having an opening for receiving a twisted wire pair; B. engagable feed means for applying a twisted wire pair to said rotatable assembly opening; C. drive means, for rotating said rotatable assembly and advancing said feed means; D. starting means for selectively engaging and disengaging said feed means with a twisted wire pair; E. said rotatable assembly having a pair of channels through which respective wires of said twisted wire pair are driven by said feed means; F. cutter means, adjoining said rotatable assembly, for selectively cutting the insulation on the twisted wire pairs protruding from said rotatable assembly; G. aligning means, engagable with said rotatable assembly, for aligning the protruding twisted wire pair ends for cutting; H. actuator means, connected to the cutter means, for stripping the wire insulation.

Claim 3
Dependent Claim
35 words
The apparatus of claim 1, further comprising: I. a separator inserted in said rotatable assembly for forming wire receiving grooves and having a saddle shaped tip which separates the ends of a twisted wire pair.
Claim 4
Dependent Claim
44 words
The apparatus of claim 1, further comprising: I. a set of wire gripping slides, mounted on said rotatable assembly, having aligned offset holes for receiving separated ends of wire pairs; J. actuator means for driving said wire gripping slides into a wire gripping position.
Claim 5
Dependent Claim
301 words
Untwisting apparatus comprising: A. a rotatable wire assembly having i. a wire pair receiving opening, ii. a pair of passageways adapted to pass single wires therethrough and having a saddle shaped junction for separating the wires of a wire pair, iii. an interconnecting passageway between said receiving opening and said pair of passageways; B. a motor connected to rotate said wire guide assembly; C. a first feed roller, also connected to said motor, for rotation; D. a second feed roller, engagable with said first feed roller for selectively feeding a wire pair into said wire pair receiving opening; E. a feed actuator for selectively engaging said second feed roller with said first feed roller; F. a centering cam fixed to said wire guide assembly for positioning the assembly such that said pair of passageways are aligned vertically; G. an insulation cutter, mounted on said wire guide assembly adjacent thereto, having i. a base plate with two holes aligned with said pair of passageways, ii. a pair of opposed insulation cutter blades slidably mounted on said base plate, iii. means to bias said insulation cutter blades apart, H. an insulation cutter actuator arranged to drive said insulation cutter blades together; I. a set of insulation gripping slides, mounted on said wire guide assembly, which are arranged to pass wire pairs from said pair of passageways through a pair of off center holes; J. a pair of opposed wire cutter blades, mounted on said wire guide assembly adjacent to said insulation gripping slides; K. a wire cutter actuator arranged to drive said wire cutter blades together and tO drive said gripping slides into an insulation gripping position; L. a wire stripping actuator, arranged to move said wire gripping slides axially in respect to said wires whereby the insulation is stripped from wire ends.
