Process and apparatus for controlling the compression during the extrusion of small parts, in particular small parts of wood, with binders

摘要

The invention relates to a process and apparatus for controlling the compression during the extrusion of small parts, in particular small parts of wood, with binders, in which the compression of the mixture is determined by the friction between the strand (3) and the walls (5, 6, 7) of the curing channel, the frictional force being generated by bracing elements (8) and their distance from one another in the length of the strand being different in such a way that the area-specific force which acts as a result on the strand is adapted to the degree of curing of the strand. <IMAGE>
