Abstract

Process for the production of thermoplastic sheets with uniformly matte surface, in which a plastic material, possibly pre-plasticized, seals in the form of a sheet in a calender provided with at least two cylinders, the dough forming a bulge in front of the opening between each pair of cylinder, while the cylinders of the calender are heated to a temperature comprised in the tremoplastic temperature range of the plastic material, and the peripheral speed of the last two cylinders of the calender are rotated with a peripheral speed ratio comprised in the ranges from 1.3 to 18 or 0.77 to 0.05, and because the sheet is removed from the cylinder that is rotated more rapidly.
