Abstract: A method for the production of laminates comprises extruding a support of acrylic nitrile-butadiene-styrene (ABS) and a coating of polymethyl methacrylate (PMMA, acrylic glass) through a sheet die. The acrylic glass forming the coating has a melt flow index of at most 2.0 (MFI 230.degree. C./3.8 according to DIN 53735) and the ABS forming the support are conducted directly to the die through different channels.

Abstract: A device to produce material webs of thermoplastic plastics, independently of the thickness at least between 100 .mu.m and 12 mm includes a single apparatus comprising cooled calender rolls mounted on a respective bottom frame and a top frame. The top frame is adjustable relative to the bottom frame between two operating positions. Of a feed roll pair, preferably directly following a sheet die, one of two feed rolls is arranged in the bottom frame and the other in the top frame. Thereby, in one operating position, the upper feed roll, and in the other operating position a smoothing ledge is associated with the feed roll of the bottom frame. The smoothing ledge is provided at the top frame and preferably has an air outlet nozzle. The top frame is preferably arranged with a slide which is displaceable in a slideway of the bottom frame.
