Abstract
The invention relates to a method for shaping the surface of extruded profiles made of thermoplastic materials with a device which is profiled to the shaping surface such that it is complimentary to the demanded shaping dimensions and presses into the continuous profile. The invention provides a method and device with whose simple, economic and high uniformity permit a material-saving production of profiles while completely adhering to the required stability at the same time. To this end, the shaping device presses the desired shaping dimensions into the continuous profile such that the wall strength of the surrounding edges of the impressions is reduced and work-hardened. The profiles are cooled and shaped into a dimensionally stable state in such a way that the height of the impressions at least correspond to the halved wall strengths of the continuous profile.
