    Abstract: An improved screw has a shaft having a surface and a central axis and at least one flight extending helically along the surface of the shaft in successive turns. A continuous groove is formed in the surface of the shaft and extends between successive, pushing and trailing, turns of the flight at a selected angle greater than zero. The groove defines at least one generally triangular land having a base aligned with a pushing turn of the flight and an apex between successive turns of the flight. The groove also defines another generally triangular land having a base aligned with a trailing turn of the flight. Barriers or dams may be provided on the lands and in the grooves. A second continuous groove may also be formed in the surface of the shaft.

    Abstract: A screw adapted for plasticizing a fiber-reinforced thermoplastic resin wherein screw lead (distance of the resin advancement in the direction of the axis per 1 revolution of the screw when it is postulated that the screw channel is 100% filled with the resin) of the screw in its compression section decreases in the direction toward the forward end of the screw. A plasticizing apparatus wherein such screw is mounted. A method for molding a fiber-reinforced thermoplastic resin by using such an apparatus. A molded article produced by such molding method. In the present invention, shear force of sufficient level can be obtained to avoid the formation of clumps while breakage of the reinforcing fibers is avoided to leave long fibers in the molded article. The resulting molded article has excellent mechanical properties, and such article is quite useful as a material for use in automobile parts and other parts.

    Abstract translation: 一种用于塑化纤维增强热塑性树脂的螺钉，其中螺杆引线（当推测螺杆通道被树脂100％填充时，螺旋每旋转一圈的轴向方向上的树脂前进的距离） 螺杆在其压缩部分沿着朝向螺钉前端的方向减小。 一种其中安装有这种螺钉的增塑装置。 一种通过使用这种装置模制纤维增强热塑性树脂的方法。 通过这种模制方法制造的模制品。在本发明中，可以获得足够水平的剪切力，以避免形成团块，同时避免增强纤维的断裂而使长纤维留在模塑制品中。 所得到的模制品具有优异的机械性能，并且这种制品作为用于汽车部件和其它部件的材料是非常有用的。

    Abstract: A single worm extruder for the mixing and processing of rubber is disclosed. The worm consists of two sections, an intake section and a mixing section. The mixing section has lands countercurrent to those of the intake section for partially backfeeding the rubber on to the intake section to provide a turbulent current of material. The countercurrent lands are interrupted by gaps which collectively have the same total area as the cross-sectional area of the intake section. The gaps in the mixing section are of constant width and have a diameter of not less than 10 mm and not more than 12 mm. The mixing section has a larger core and outer diameter than the intake section.
