ABSTRACT:
A method and an apparatus for producing multilayer panels. In the method for producing multilayer panels from extrudable plastic, two plastic strips are fed from extruders to a roll-arrangement and are joined together, with an inclusion of material therebetween. The purpose of the invention is to produce predeterminable patterns and structures upon introducing the material. In order to achieve this result, the material in the form of threads, is introduced individually and independently of each other into a gap in an arrangement of rolls, and the threads are aligned, by means of guide-means, in relation to each other and to the gap.
