ABSTRACT:
A screw housing with a wearing insert for a two-shafted screw machine wherein the wearing insert has two spaced parallel bores to accommodate screw shafts located with their mutually parallel longitudinal axes in the principal plane of symmetry of the wearing insert. These shafts are spaced apart so as to form saddles at the connecting point of the bores. The insert housing has an external cross-section which is substantially constant along its axial length and is arranged in a cavity of the screw housing having the same cross-section.
