A section of an extruder housing, comprising an inner border (11) defining an inner space (6) for receiving a worm and partially comprised of at least one inner segment (7) that is made of a friction-resistant material. Each inner segment (7) has a partially circular cross-sectional inner surface. The inner segments (7) are tightened by at least one longitudinal wedge (8) on an outer housing (2). The inner border (11) is made up of partial areas of the inner segments (7) and the longitudinal wedge (8). |
