ABSTRACT:
A device for continuously stripping the insulation off of electrical wires, particularly solid conductors as opposed to stranded conductors, for the re-cycling thereof in the manufacturing process, including an initial cutting section and a subsequent stripping or insulation removal section. The cutting section utilizes two opposed, interdigitated sets of dual rotary "cutters," each having two juxtaposed cutting edges or blades, only one of which however is used to cut at any one time. One "cutter" is used to form a "V" section to laterally hold the wire in position, while the other opposed cutter has one of its blades located centrally within the "V" section of the other holding "cutter" (note FIG. 4). When the insulated wire is passed through the device, the cutting blade cuts through the insulation continuously down along the longitudinal length of the wire, and the wire with the cut insulation is then passed through a stripping orifice in a conical "extruder" section to remove the insulation on a continuous basis. The cutting pressure is adjustable by a spring biased T-handle mechanism which includes two opposed, pivoting arms carrying the upper set of rotary blades which allows them to be pivoted in a generally perpendicular direction with respect to the lower rotary blades. The four cutter blades are also laterally adjustable in position on threaded shafts so that each of the four blades can be utilized in turn as the actual cutting blade. After being stripped, the bare conductor is wound onto an automatic coiler which pulls the wire through the device.
