Abstract
A device for heated wedge pressure draw welding of separating seams of a composite plastic profiled hollow section. The device is drawn through the hollow chamber of a plastic profiled hollow section, in the course of which heating bars plasticize the seam walls of the separation seams and the plastic welding wires needed for welding. The plasticized plastic welding wires are pressed into the plasticized separation seams by press elements as the device is continuously drawn through the plastic profiled hollow section by a drawing device and a drive motor, the speed of which can be controlled.
