<p>A welding machine (1) for thermoplastic products, of the kind comprising a couple of molds (5, 6) suitably shaped so as to follow the shape of the components (16, 17) that have to be welded and that are joined together along one of their edges by interposing a hot plate (7). The machine (1) is provided with a mold-holding frame on which the molds (5, 6) and the hot plate (7) are mounted, so as to form a monolithic unit with said frame. The machine (1) has quick locking and unlocking means so as to allow to replace the frame with another similar one also provided with a couple of molds and a hot plate. <IMAGE></p> |
