Abstract
Comminuted pieces originating from bituminous membrane are subjected to agitation in a first extrusion screw section. This has a greater pitch than that of the second extrusion screw, which follows it. An Independent claim is included for the corresponding extruder, which preferably includes speed control. Preferred features: In their travel across the extruder, pieces (15) pass through at least three successive stages in extruders (13, 12). At each stage, the screw pitch reduces in comparison with that of the previous stage. For heating taking place in each stage, a temperature range is prescribed. Feed is intermittent.
