Abstract
An extruder for the plastification and extrusion of a rubber mixture in the form of two cold material strips through two inlet passages (4, 5) has in a housing (1) two gears (2, 3) meshing with one another in the manner of a gear pump. The inlet passages (4, 5) are provided each in an insert (8, 9) which is held replaceably in the housing (1). In this manner it becomes possible, by exchanging the inserts (8, 9) to adapt to various materials to be worked by the extruder.
Claims16
An extruder for the plastification and extrusion of a rubber mixture fed in the form of at least one cold strip of material, comprising two gears disposed in a housing and meshing with one another, at least one inlet passage at the inlet side for the material strip and one outlet in the circumferential surface of the housing, the direction of rotation of the gears being such that the material strip is advanced between a gear and the housing to an outlet, wherein the inlet passage is provided in an insert held releasably in the housing of the extruder.
