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. Movement of the first set of cutting blades and the second set of cutting blades towards each other produces the removable sleeve portion during displacement of resin from the resin covered filament.
