摘要： A degassification device for a screw extruder which processes plastic material in which the extruder has a hollow housing and an extruder screw rotatable in the housing, the degassification device having a pair of degassification screws disposed adjacent to the extruder screw for rotation about axes parallel to the axes of rotation of the extruder screw. A housing headpiece accommodates the degassification screws and is in communication with the extruder housing such that gas and vapor produced in the extruder housing can flow radially therefrom into the housing headpiece for discharge therefrom. The degassification screws have threads which interengage one another and they are driven in the same direction of rotation. The housing headpiece has adjacent longitudinal bores which overlap one another and respectively receive the degassification screws therein with their threads interengaged with one another. The crests of the threads of the degassification screws pass in close proximity to the inner surface of the housing headpiece and the extruder screw. The length and cross sectional profile of the degassification screws are such that upon rotation of the screws, the overlapped bores in the housing headpiece are longitudinally and transversely traversed by the screws substantially in entirety.

摘要： A co-rotating twin-screw kneader has a casing which has two axially parallel bores, defined by the casing wall and which intersect with one another in a region to form gussets in said casing wall adjacent the intersecting region. Two axially parallel shafts which are arranged to be driven in the same direction of rotation are each arranged in a respective one of the bores and multi-flight kneading disks having crests associated with the casing wall are mounted in non-rotary manner on at least part of the length of each shaft. Each kneading disk on one shaft is associated with another disk on the other shaft in a plane perpendicular to the axes of the shafts and the disks are arranged to be moved past one another in a virtually clearance-free manner in the intersecting region of the bores.In order to achieve maximum flow rates and optimum melt homogeneity of material by using constructionally simple measures, the casing wall is dimensioned in such a way relative to the kneading disks, accompanied by the formation of a definite clearance between the casing wall and the crests on the kneading disk, but ##EQU1## in which Dg=diameter of the boresa=center-to-center distance of the boresn=number of flights on each kneading disk.

摘要： A screw-type extruding machine includes a housing; a driveable shaft disposed inside the housing and including a rotational moment transfer element; and at least one screw element. The screw element has two ends and defines a longitudinal groove therein for receiving the rotational moment transfer element of the shaft, the shaft thereby transferring its rotational moment to the screw element. The groove is configured such that it defines two expansion regions, each expansion region having an axial extent, the groove having side surfaces which diverge with respect to a longitudinal axis of the groove along the axial extent of each expansion region in a direction toward a corresponding one of the two ends of the screw elements, a width of the groove thereby increasing in a direction toward its two ends along each expansion region.
