Abstract
A device for sizing and cooling an extruded flat product made of plastic material includes at least two main rolls and a polishing stack including a plurality of rolls arranged in tandem and disposed downstream of the main rolls. An adjustable sizing nip is disposed between all of the adjacent respective rolls. The sizing nip is adjustable so as to pinch the flat product during an extrusion process to a greater or a lesser extent.
