Abstract:
1. An apparatus for stripping of insulation lengthwise from an insulated wire or cable having an inner metal core on a continuous basis for the recovery of the metal core, the apparatus comprising: a. a supporting frame structure; b. a first shaft, c. the feeder wheel having a first generally “V”-shaped groove cable guide path that is adapted to receive and pull the insulated wire or cable through the apparatus when the drive rotates the feeder wheel, d. a cutting assembly, e. the feeder wheel has a second generally “V”-shaped groove cable guide path, f. the second shaft of the cutting assembly, has mounted thereon a second circular cutting tool which is able to rotate, wherein the second cutting tool is aligned with and cooperates with the second generally “V”-shaped groove cable guide path, wherein at least one of said first and second generally “V” shaped groove cable guide paths is formed with shoulders which are adapted for gripping the insulation of the cable, and a. the first and second groove cable guide paths have first and second interior tapering faces that are generally frusto-conical, and b. within the first and second interior faces at one or more selected locations there are formed relieved slots, the slots being formed with i. a first descending surface that tapers from either the first or second interior face deeper into the feeder wheel in a direction opposite of feeder wheel rotation, descending on either the first or second interior tapering face until it reaches one of said shoulders that defines the other end of the slot with respect to the rotation of the feeder wheel, ii. said shoulder providing a deep sharp face which is generally perpendicular to either the first or second interior face of the first or second groove cable guide path, the shoulder being adapted for penetrating the outer cover of cable insulation, gripping the cable and pulling the cable through the apparatus; wherein the first descending surface of the relieved slot creates a gradual, prolonged descent from either the first or second interior tapering surface of the first or second groove cable guide path to the shoulder.
