Abstract: A rubber sheet monitoring apparatus (1) comprises a first imaging unit (11), a second imaging unit (2), a first generation unit (142) and a second calculation unit (146). The first imaging unit successively acquires images of a first optical cutting edge (CL1) formed on a front surface of a rubber sheet (6). The second imaging unit successively acquires images of a second optical cutting edge (CL2) formed on a back surface of the rubber sheet. The first generation unit performs, for each of the successively acquired images of the first optical cutting edge, generation of first data (D1) representing height variation of a widthwise cross-sectional edge of the rubber sheet using the image of the first optical cutting edge, and performs, for each of the successively obtained images of the second optical cutting edge, generation of second data (D2) representing height variation of a widthwise cross-sectional edge of the rubber sheet using the image of the second optical cutting edge.

Abstract: A kneader internal inspection device according to the present invention suspends and supports a photographing unit, which is arranged in an interior of a kneader and which photographs the interior, so as to be vertically movable in the interior of the kneader. Therefore, such a kneader internal inspection device is capable of easily inspecting the interior of the kneader.

Abstract: A kneader includes a kneader main body including a casing including a kneading chamber and a kneading portion that is disposed in the casing and kneads a material in the kneading chamber. The material supplied to the kneading chamber includes a resin material, an inorganic additive added to the resin material, and a coupling agent for enhancing affinity of the inorganic additive for the resin material. The kneader further includes a kneading monitoring portion that monitors a kneading state of the material by detecting a reaction product that is generated by a reaction between the coupling agent and the inorganic additive.

Abstract: Disclosed are: a composite formed article which is usable even in a high-temperature environment and less suffers delamination between a foamed resin sheet and a metal sheet; and a formed article precursor (laminated sheet) which enables the manufacture of the composite formed article. The laminated sheet includes a foamable resin sheet containing a resin and a foaming agent; and, provided on both sides of the resin sheet, a pair of metal sheets each through the medium of an adhesive. The resin has a melting point of 145° C. or higher, and the adhesive has a melting point substantially equal to or higher than the melting point of the resin.

Abstract: The present invention provides a member in contact with a rubber material, the member being characterized in that the member has a surface in contact with the rubber material, and that the contact angle of the surface thereof in contact with the rubber material is 40° or more when a liquid rubber to be tested is placed on the surface.

Abstract: In a method of manufacturing a fiber-reinforced strand, the fiber-reinforced strand is so manufactured that the cross-section thereof becomes as circular as possible. Particularly a method of causing a reinforced fiber bundle 3 to pass through a resin bath means 7 and, thereafter, twisting the reinforced fiber bundle 3. The resin bath means 7 includes an impregnation region 21 where the reinforced fiber bundle 3 is impregnated with a thermoplastic resin 5 and a twisting region 22 where the reinforced fiber bundle 3 after the resin impregnation can be twisted, and the reinforced fiber bundle 3 after the resin impregnation is twisted in such a manner that a twist pitch P imparted to the reinforced fiber bundle 3 after the resin impregnation within a length L in the twisting region 22 satisfies L/3?P?3.15/90×(dtex)1/2.

Abstract: A process for producing an impregnated-yarn cloth which is woven fabric configured of impregnated yarns, which has satisfactory shaping properties and, despite this, has a fine texture of the reinforced fiber bundles, and which gives a molded object having excellent strength. The process for producing an impregnated-yarn cloth (1) is characterized by impregnating fiber bundles (2) with a thermoplastic resin (5) held in a molten state in a resin tank, while or after twisting the fiber bundles (2) at a rate of 20 twists/m or more and 700 twists/m or less, to form an impregnated yarn (3); and knitting or weaving the thus-formed impregnated yarns (3) to obtain the impregnated-yarn cloth (1).

Abstract: A kneading segment kneads materials such that insufficiently kneaded portions would not remain as gel. The kneading segment is rotatably disposed on a kneading screw housed in a barrel having an inner cavity, and is provided with a kneading flight which kneads the material in the barrel by rotating according to the kneading screw's rotation. The top surface of the kneading flight is formed with a concaved cutout section. The cutout section is surrounded by two side surfaces, which face the axial direction, and a bottom surface, which is disposed between the side surfaces. The bottom surface of the cutout section is formed in a tilted planar shape in relation to the top surface. The opening of the cutout section, which faces one side of the rotational direction of the kneading screw, has a larger area than the opening which faces the other side.
