摘要：1. Method of producing profiled sealing strips formed from rubber or rubber-like plastics material by extrusion, the profiled sealing strips having a clamping portion with U-shaped cross-section and with clamping lips which are moulded to fit on the inner surface of the two arms of the clamping portion in alignment and are inwardly inclined at an angle, characterized in that each respective pair of clamping lips disposed opposite to each other is continuously extruded as an angled wall, and subsequently the clamping lips are opened by mechanical separating dies, which are guided in the direction of extrusion, to form their U-shaped cross-section ready to be fitted into position.
