A multi-shaft screw-type extruder comprises - a casing; - two parallel and partially intersecting casing bores; - two shafts disposed in the casing bores and drivable to rotate in the same direction; - screw elements non-rotatably mounted on the shafts; and intermeshing kneading disks, which are non-rotatably mounted on the shafts and the respective crest portions of which are reduced in relation to the disk width for mixing-and-scraping-studs to form, which are located on the periphery. The mixing-and-scraping-studs on each kneading disk are axially misaligned relative to each other such that their peripheral faying surfaces jointly cover the entire disk width.
Extrudeuse à vis à axe multiple comprenant les éléments suivants : une enveloppe; deux alésages d'enveloppe parallèles qui se recoupent en partie; deux axes placés dans les alésages et entraînés pour tourner dans le même sens; des vis montées sur les axes de manière à ne pas tourner; des disques pétrisseurs engrenants, montés sur les axes de manière à ne pas tourner, dont les sommets sont inférieurs à la largeur du disque de façon à former des éléments mélangeurs et racleurs, situés à la périphérie. Ces éléments ne sont pas alignés dans le sens axial de façon que leurs surfaces internes périphériques recouvrent ensemble toute la largeur du disque.
