Extrusion line and process for foam extrusion with at least two parallel cooling devices / cooling extruders coupled downstream to the extrusion line

摘要

The cooling units (2) are identical or they are so controlled and regulated, that the plastic melt leaving them is largely identical in its material properties. An Independent claim is also included for the corresponding method, in which the melt streams are brought to the same temperature and pressure before uniting and molding (4) them.
