Abstract:
A method for shaping the surface of a C-shaped or U-shaped extruded profile having side walls and made of thermoplastic materials with a shaping device which is profiled complimentary to the required shaping dimensions, comprising:cooling the extruded profile; supplying the rigid extruded profile to the shaping device; forcing apart the side walls; pressing the extruded profile into the desired shaping dimensions with the shaping device to provide a continuous C-shaped or U-shaped profile such that the surrounding edges of impressions reduce side wall thickness of the C-shaped or U-shaped profile; solidifying the C-shaped or U-shaped profile by cooling; holding apart the C-shaped or U-shaped profile by cooling; returning the C-shaped or U-shaped profile with reduced side wall thickness to the position before the side walls were initially forced apart; and cutting and depositing the C-shaped or U-shaped profiles into defined units.
