    摘要： An extruder screw for use in a barrel of an extruder for forwarding thermoplastic polymer from a first end to a second end of the extruder. The extruder comprises a transition section and at least one flight extending substantially along the length of the screw. A dam is positioned at the point where the rapid melting of the solids starts to slow down and the rate of solid bed width decrease approaches zero. The dam provides the screw with a high output of extrudate and close control of the residence time of polymer particles as they are transported through the screw, resulting in an extrudate which is uniformly melted and which is substantially free of degradation products and/or entrapped air.

    摘要： A plasticating screw having a mixing section comprised of two flow channels separated by barrier flights having axially spaced undercut sections and areas of compression and decompression in each channel. Inhomogeneities in the material being plasticated are distributed in both the forward and back directions by means of pressure driven cross-flows caused when the material encounters a section of a channel having a decreasing depth adjacent an undercut section of the barrier flight.

    摘要： A screw for use in an extruder barrel for plasticizing plastic material from a solid phase to a viscous form wherein the feed screw has a cylindrical core with a helical flight extending for the full length of the screw. A selected portion or portions of the screw's core has a polygonal cross section whose apexes are parallel to the axis of rotation of such screws to thereby more precisely control the plasticizing action of the plastic material, its viscosity and temperature while providing a thoroughly mixed and homogeneous melt.

    摘要： A double-screw extruder for thermoplastic materials, with a first and a second extruder screw, whereby the extruder screws have an inlet and an outlet and a core, helically extending screw flights being arranged through the core from the inlet to the outlet, so that the screw peaks and valleys are circumferential, and the peaks of the first screw penetrate into the valleys of the second screw, and vice versa. The screw flights may have a geometry which is step-shaped in cross section, whereby the steps may be provided such that the stepped course of the peaks is congruent with the stepped course of the valleys.

    摘要： Screw press, preferably for removing liquid from a material to be conveyed, comprising a screw shaft (1) complete with a helical conveying flight (2) mounted on the screw shaft (1) and a housing shell (3) surrounding it, where a transport channel (4) is formed for the material to be conveyed between the screw shaft (1), the conveying flight (2), and the housing shell (3). In order to prevent conveyed material components from adhering to the screw shaft (1), and thus uneven filling of the transport channel (4), the invention provides for the screw shaft (1) to have a surface profile (5), at least in one section of the transport channel (4).
