ABSTRACT:
An apparatus for forming shaped material from a raw material employs a substantially cylindrical housing 3 with a screw shaft 2 arranged in it. A frontal end surface of the housing, located at the downstream end is closed by a counter-pressure member 9 which, together with the housing 3, limits a discharge opening. The counter-pressure member is held against conveyed material by a force of predetermined magnitude acting opposite the conveying direction. Surprisingly, this results in a high compactness and a good stability of shape of the shaped material, and also facilitates a starting of such an apparatus. Removable teeth define an orifice.
