Abstract (en)
[origin: EP0345557A2] A description is given of a method for controlling densification during extrusion and tube extrusion of small parts, in particular small parts composed of vegetable matter, using binders, in which the filling and pressing chamber and the cooling and moulding channel, as well as the hardening channel are longitudinally divided by partition walls and form at least two or more filling and pressing chambers, possibly cooling and moulding channels and hardening channels. The invention is characterised in that for the purpose of controlling the densification of the strands, the friction takes place, entirely or partially or in conformity with the circumferential part relating to the circumference of the associated extruded profile or profiles, through the pressing of the walls of the heated partition walls against the strands by means of the same fluid heating and hydraulic medium in the same heating and hydraulic circuit.
