摘要： The invention relates to a multiscrew, continuous mixing machine for plasticizable compounds with two screws, which rotate in a housing and which penetrate the cylindrical part of the housing that envelops the screw concerned and exhibit feed and metering sections and inbetween at least one homogenizing section and a mixing section, whereby the feed and metering sections are formed by intermeshing conveying screws, which rotate in the same direction and are arranged in the mixing elements, which are opposite the homogenizing and mixing sections and whose edges travel past each other with little clearance while rotating, whereby to form a chamber extending above the mixing elements, the edges maintain a distance from the part of the housing enveloping said edges that is significantly greater than the clearance. The mixing elements comprise process screw elements, whose lengths are in essence identical and which exhibit such a pitch that within the chamber the one process screw element feeds forward and the other process screw element feeds backward.

摘要： A screw type, polymeric material extruder with an elongated body having a cylindrical bore with a hollow screw in the bore, the screw having external and internal threads. A cylindrical body is within the internal threads, and the screw with the wall of the bore and with the cylindrical body forms, respectively, an external material flow chamber and an internal material flow chamber. The cylindrical body can have channels for heating fluid and for additives or dyes. The screw can have openings for feeding one material to a single extrusion head with one mouth by way of both chambers, or the chambers can be supplied with the same or different materials which are fed by way of the chambers to an extrusion head with two mouths for applying the latter materials separately.

摘要：挤压机的螺杆提供了三种新的结构，它属于化纤工业和塑料工业中的挤压(出)机上的新型螺杆。其三种结构特征分别为：进料段变短，压缩段的副螺纹位于主螺纹的左侧，副螺纹的起始端与结束端均为通开，副螺纹的外径与主螺纹的外径单面间隙增大，并且通过改变副螺纹的根径，增加熔体压力。又在这种螺杆的基础上，于相应的部位增设了屏障段或者混炼段构成另外两种结构，使其适应不同品种物料，提高熔体质量，与普通螺杆相比挤出量可提高1.4～2倍，降低能耗15～20％。

摘要： The invention relates to a method and an apparatus for manufacturing an extruded plastic product, the apparatus comprising at least one rotor (1) and at least one stator (2, 3) with a feed gap (4) provided between them, a groove (7) being situated on the other side of the feed gap (4), the groove pressing the material to be extruded out of the apparatus when the rotor (1) is rotated. The cross section of the groove (7) remains substantially unchanged. At the opposite side of the feed gap (4) there is positioned a countergroove (8) in such a way that a processing cavity consisting of the grooves (7), the countergrooves (8) and the clearance between them decreases at least partially continuously along the axis of the extruder. The deformation energy of the material can thus be kept as small as possible due to the unchanging cross section of the groove (7), and the material stays in the groove (7) due to the placement of the flights (7a, 8a). The material is made to mo ve rotatably, which enables the manufacture of a laminar plastic product (11). Further, materials that would otherwise be difficult t o process can also be extruded effectively.
