Abstract

1. Method of smoothing surfaces of calandered or extruded thermoplastic plastics sheets or profiles, in which the set, cooled plastics sheet or the profile is continuously conducted at below a specific pressing pressure past at least one grinding roller which is rotating and oscillating transverse to the transporting direction, characterised in that on conducting the plastics sheet or profile with a speed of 1 to 10 m/min the oscillation frequency of the grinding roller amounts to 50 to 300 Hz, the peripheral speed thereof amounts to 5 to 30 m/sec. and the pressing pressure amounts to 0.1 to 3 bar.
