Method and arrangement for mfg. plastic window frames

摘要

In a method of mfg. plastic window frames, sections (19) are put in a welding jig (1) and are welded together to form a frame, which is cured in a separate area and removed for further processing. Also claimed is an arrangement for carrying out the method comprising a welding jig which permits all four corners of the frame to be welded simultaneously and a curing set-up (3), to which the frame is transported on a conveyor (13) comprising twin belts (13a, 13b). The curing station has a similar conveyor (15a, 15b).
