Abstract: A tool for stripping the outer layer of insulation on a multi-wire cable such as romex, comprises a jaw and a claw, each being mounted to the rotating members of a plier-like apparatus. The claw has a sharp cutting edge, and the jaw holds the cable in position while it is being pierced by the sharp cutting edge of the claw. The plier-like apparatus closes the claw and jaw together, thus causing the claw to pierce the cable's outer insulation layer as it is held in the jaw. A user then pulls the cable through the jaw, causing the outer insulation layer to be slit as it moves past the claw. The jaw that holds the cable is in an offset position relative to the plier-like apparatus, such that the cable lies off to the side of the plier-like apparatus while a user pulls the cable through the jaw.
Abstract: A mechanical stripping apparatus for displacing resin from a resin covered filament by forming a removable sleeve portion between opposing filament ends. The mechanical stripping apparatus comprises a first clamp for holding a filament at a first location and a second clamp having a separation from the first clamp and in axial alignment therewith for holding a filament at a second location. A first set of cutting blades adjacent to the first clamp is positioned for cutting into resin around a resin covered filament proximate to the first location. The mechanical stripping apparatus also includes a second set of cutting blades adjacent to the second clamp for cutting into resin around a resin covered filament proximate to the second location, such that a distance separates the first set of cutting blades from the second set of cutting blades. The distance between sets of cutting blades is less than the separation between the clamps.
