ABSTRACT:
A method and apparatus for producing thermoplastic frames for fenestration in which extruded frame members are cut to length, heated to a selected temperature uniformly throughout their cross section to soften the material and while heated, profiling selected portions of the cut members, driving a fastening clip with a hole therein into one of the cut members, and drilling holes in portions of the cut members in locations for coaxial alignment in assembly of the cut members, a hole in the fastening means plate coaxial with one of the drilled holes, and placing the members in selected angular assembled relation and inserting and threading a securement member into the aligned holes of the cut members and the fastening plate for retaining the frame members in assembled angular relation. An apparatus which includes an oven through which a conveyor transports cut members in diagonal relation for uniform heating of the members, a profiling station for shaping surfaces of the cut member, a driving station for embedding a fastener plate in a cut member; and a drilling station for making holes in selected portions of the cut members for assembly of the cut members in angular relation and with a screw member passing through said holes and a hole in said fastening plate for providing a rigid unyielding corner joint of such cut members.
