Abstract

Method and apparatus for producing sealing strips and similar profiled strips of rubber and rubber-like elastomers. Rubber-like profiled sealing strips for window or door openings are frequently provided with overlay strips to facilitate installation, to enhance the relative movements, or for aesthetic-visual reasons. The material of these overlay strips generally differs considerably from the material of the base main strip. The manufacture of such two-material profiles can be undertaken in a single extrusion step by joining and directly combining a prefabricated overlay strip with the main strip in the extrusion head of an extrusion press, where the shape is provided for the profiled strip. By stretching the overlay strip, the adhesion of the latter to the main strip is significantly improved.
