Improved Methods of Manufacturing Flexible Screen Frames
A method for manufacturing a flexible screen frame from a flat wire having a coating includes bending the wire to substantially match the desired shape of the screen frame. The flat wire has a first end and a second end and the coating is removed from both ends to create bare wire portions that can be welded. A shrink tube is then slid onto the wire and moved away from the ends to be welded. Then, the ends are welded together and the shrink tube is used to cover the bare wire portions and the weld point. A screen mesh is then melted onto the frame.
1 . A method of manufacturing a flexible screen having a frame with a desired shape and a screening mesh having a coating, the frame further constructed from a flat wire having a coating, the method comprising:
bending the wire to substantially match the desired shape; the wire having a first end and a second end;
removing the coating from the first end and the second end to create bare wire portions adjacent the ends;
sliding a shrink tube onto the wire and moving it away from the ends;
welding the ends together at a weld point to complete the desired shape;
positioning the shrink tube over the bare wire portions and the weld point;
heating the shrink tube to cause it to seal to the wire; and
bonding the screening mesh coating to the flat wire coating and the shrink tube.
2 . (canceled)
3 . The method of claim 1 , wherein bonding the screening mesh further comprises placing the screening mesh in position on the frame and heating the screening mesh, the shrink tube, and the coating on the frame until they melt together.
4 . The method of claim 1 , wherein the flat wire is comprised of spring steel.
5 . The method of claim 1 , wherein the coating is comprised of a thermoplastic material.
6 . The method of claim 5 , wherein the thermoplastic material is one of the following:
PVC, nylon, polyethylene, polypropylene, and polystyrene.
7 . The method of claim 1 , wherein the shrink tube has an inner surface that makes contact with the frame, the inner surface having a thermoplastic adhesive for sealing with the frame.
8 . The method of claim 1 , wherein the desired shape has a plurality of corners and the weld point is located between four and eight inches from any of the plurality of corners.
9 . The method of claim 1 , wherein the bare portions extend in the range of one to two inches from the first end and the second end.
10 . The method of claim 1 , wherein the shrink tube contains printed information regarding one or more of sizing, account name, product type and warranty information.
