Abstract
An end stripper that strips a polymer coating from flexible screen frame material, the end stripper including a table having a tabletop and ground engaging legs, an induction coil coupled to an induction power supply, a clamping assembly located proximate the tabletop and sized to receive a first end portion of flexible screen frame material therein. The induction coil positioned and shiftable to receive the first end portion of the flexible screen frame material therein and operable to heat the first end portion by induction thus softening a polymer coating of the flexible screen frame material. A first stripping jaw strips the polymer coating from the first end portion.
Claims8
A method of stripping a polymer coating from a flexible screen frame material, the method comprising:
- inserting a first end portion of the flexible screen frame material comprising a polymer coating into a clamp assembly so that the first end portion of the flexible screen frame material abuts a first stripping jaw;
- engaging the clamp assembly to fix the first end portion in location;
- moving an induction coil to encompass the first end portion of the flexible screen frame material;
- energizing the induction coil thereby heating the first end portion of the flexible screen frame material;
- shifting the induction coil and the first stripping jaw to a first position wherein the stripping jaw encompasses the first end portion of the flexible screen frame material;
- closing the first stripping jaw;
- shifting the induction coil and the first stripping jaw in a first opposing direction thus stripping the polymer coating of the flexible screen frame material;
- opening the first stripping jaw;
- and
- releasing the clamp assembly to facilitate removal of the first end portion of the flexible screen frame material.
A method of stripping a polymer coating from a flexible screen frame material, the method comprising:
- inserting a first end portion of the flexible screen frame material comprising a polymer coating into a clamp assembly while the flexible screen frame material is supported on a horizontal table so that the first end portion of the flexible screen frame material abuts a first stripping jaw extending upwardly through an opening in the table;
- engaging the clamp assembly to fix the first end portion in location;
- encompassing the first end portion of the flexible screen frame material in an induction coil;
- energizing the induction coil thereby heating the first end portion of the flexible screen frame material thus rendering the polymer coating softened or at least partially molten;
- shifting the induction coil and the first stripping jaw to a first position wherein the first stripping jaw encompasses the first end portion of the flexible screen frame material;
- closing the first stripping jaw;
- shifting the induction coil and the first stripping jaw in a first opposing direction thus stripping the polymer coating of the flexible screen frame material;
- opening the first stripping jaw;
- and
- releasing the clamp assembly to facilitate removal of the first end portion of the flexible screen frame material.
