Method of manufacturing a bendable core, core as obtained by the method, and profile comprising such a core

摘要

To produce a flexible seal (8) for automobile joints, which can be bent and profiled to fit with a reinforced sealing profile (10), a thermoplastic strip or preform (2) is extruded (1) and calendered (3,4) to give it the required structure and pattern. The shaped material is cooled and calibrated. The shaped sealing material has a U-, V-, S-, L- or W-shape.
