Abstract (en)
[origin: WO9633855A1] A process and device for producing co-extruded foam composites having any patterns in their mass. The foam composites are taken together from at least two foamable polymer melt streams with different physical and/or chemical properties to an extruding tool after the application of a gas, at least partially mixed and/or twisted and then co-extruded.
