发明名称 Profiled strip with smooth reinforcing insert and method of its manufacture
摘要 A method for producing a profiled strip and the resulting profiled strip, wherein the profiled strip comprises a flexurally elastic reinforcement insert deformed, for example, into a U-shape, covered by a covering of rubber, or the like which is preferably extruded over the insert. The insert is a metal strip which is stamp cut for defining a continuous web extending across the strip and for defining at least one plurality of rungs in the metal strip. The rungs extend away from the web and preferably are defined on both opposite sides of the web. The rungs are defined by a stamp cutting operation so that after the insert is smoothed following the stamp cutting, there is no spacing between neighboring edges of adjacent rungs.
