Device for joining ends of material strips |
摘要 |
A device for joining ends of material strips of rubber or plastic materials with rubber properties, wherein the ends to be joined have areas of reduced wall thickness and wherein the end cut first is stretched shortly before joining the two ends, includes a plurality of force-transmitting elements positioned adjacent to one another transverse to a longitudinal direction of the material strip at a forward end thereof and acting on one face of the material strip. At least the force-transmitting elements positioned at the areas of reduced wall thickness of the forward end are movable in the longitudinal direction of the material strip for stretching the forward end of the material strip at least within the areas of reduced wall thickness.
