Abstract

A method for producing a twin screw cylinder provided with or having a wear-resistant coating, in which two bores, which extend essentially parallel to each other and overlap each other, are produced in a cylinder and then two liners are inserted into the bores, the liners having an essentially C-shaped cross-section, continuing from each other in the overlapping region of the bores, forming the inner surface of the bores, and serving as a wear-resistant coating. First, a tubular liner is inserted into a first bore and then is cut to form the C-shaped cross-section in accordance with the diameter of the other bore and after this, a second tubular liner is inserted into the second bore and then is cut to form the C-shaped cross-section in accordance with the diameter of the inner surface in the first bore formed by the first liner.
