    Abstract: The kneading disc segment according to the present invention comprises plural disc sets each comprising two kneading discs and mounted on a kneading screw (3) which is for kneading a material while feeding the material to a downstream side. Disc sets each comprising a first kneading disc positioned on an upstream side and a second kneading disc, the second kneading disc being mounted continuously with and downstream of the first kneading disc so as to have a phase difference δ of an acute angle relative to the first kneading disc, are disposed continuously in the axial direction of the kneading screw. The first kneading discs in two continuous disc sets have a phase difference of 180°. With this construction, it is possible to attain a higher degree of kneading than in the conventional neutral kneading disc segment.

    Abstract: A method and apparatus for removing hot volatiles and moisture from particulate plastic material being fed for injection or extrusion molding by a plasticizing screw which rotates in a heated barrel. Flow control means, such as a conveying screw or rotary valve, drop the particulate material downward through a vertical feed passage extending to an opening in the barrel. At the same time, suction is applied to remove hot volatiles which are released through the opening in the barrel as the particulate plastic material is gradually melted as it is compressed by the screw. The rate of feed of the particulate material is restricted so that the barrel of the plasticizing screw is only partially filled near the opening, thereby improving the withdrawal of the gases from the barrel. The incoming particulate material is preheated by a continuous flow of hot air through it as it passes through a tubular guide member. The air flowing to the preheater passes through a heat exchanger where it recovers some waste heat from the hot gases withdrawn from the barrel to improve efficiency and reduce power costs.

    Abstract: A kneading segment includes plural wing portions integrally formed along an axis such that angles, around the axis, of the plural wing portions are shifted. At a part of a leading end of each wing portion where a wing leading end surface and a wing surface connect with each other, a first flow surface facilitates flow of material between the wing leading end surface and the wing surface. At a part of a base end of each wing portion where a wing surface and a wing side surface of another wing portion adjacent to each wing portion connect with each other, a second flow surface facilitates flow of material between the wing surface and the wing side surface. Since such a configuration prevents material from staying between parallel kneading segments, impurities are prevented and will not mix into normally kneaded material.

    Abstract: The present invention discloses a generic method for producing void and gas occlusion free materials, as well as apparatuses for batch and continuous production of same. This generic method can be utilized in the production of a wide variety of polymeric compounds and composites and specifically encompasses the two ends of the polymeric composite spectrum, that is, polymer concretes on the one hand, and fiber-reinforced polymer composites on the other. The composite materials of the present invention are characterized by visual count as being void and gas occlusion free to the level of 1 micron at 1250× magnification. Concomitantly, the invention produces useful polymer concrete materials which exhibit substantially improved integrity for easy machining at high speeds, and high dielectric and mechanical strength, as compared with composite materials produced by conventional methods. Thus, one particularly well-suited application for the materials of the present invention is the class of high voltage electrical insulating materials and insulators where the presence of voids, or gas occlusion flaws, may have deleterious effects, leading to their early failure.
