ABSTRACT:
A dimensionally stable plastics section, for example a window section, formed from a plastics extrudate and being provided thereon with an extruded layer, for example a sealing or damping device or a protective strip, is manufactured by extruding the section, calibrating it, and cooling it to ensure its dimensional stability, heating part of the surface of the section, to which the layer is to be applied, extruding the layer onto the heated part of the surface of the section so that the extruded layer is bonded thereto and using a take-up device to grip the finished section to remove it.
