摘要： PURPOSE:To obtain a liner excellent in the drawing ability, rigidity and the like, by forming a non-foamable skin layer made of propylene group polymer on each surface of a laminated foamed sheet formed of two bridged foamed sheets which are made of propylene group polymer and an ethylene group polymer and are laminated one upon another. CONSTITUTION:This trim for an automobile is produced by forming non- foamable skin layers 2, 3 made of propylene group polymer and ethylene group polymer, respectively on both front and back surfaces of a laminated foamed sheet 1 which is formed of two bridged foamed sheets 4, 5 made of polypropylene group polymer and ethylene group polymer and laminated one upon another through the intermediary of a thermally fused layer 6. In this arrangement, the ratio of the solid thickness Tf of the bridged foamed sheets 4, 5 and the thickness Ts of the non-foamable skin layers 2, 3, that is, Ts/Tf, is selected to be 1 to 50. Further, the thickness T1 of the thermally fused layer 6 is selected to be 1 to 0.5mm while it is to be 1 to 25% of the thickness Tr of the bridged foamed sheets 4, 5. With this arrangement, the moldability thereof is satisfactory so that a deep and sharp molded article having a good external appearance may be easily obtained by a thermoforming process.

摘要： PURPOSE:To contrive to save the weight of a trim itself and improve its resistance to shock, heat resistance, soundproofing property and the like by a method wherein two crosslinked foamed sheets, each of which consists of propylene- based polymer and ethylene-based polymer are laminated to each other. CONSTITUTION:A non-intumescent skin layer 3 is laminated to one side 6a of a crosslinked foamed sheet 6, which consists of propylene-based polymer and ethylene-based polymer, by extrusion-laminating a molten resin sheet 10 made of propylene-based polymer in order to mold a laminate A. At this time, uneven pattern 4 such as emboss pattern or the like is formed on the skin layer 3 by the uneven pattern of a hot pressing roll 9A. On the other hand, a non-intumescent skin layer 2 is laminated to one side 5a of a crosslinked foamed sheet 5, which consists of propylene-based polymer and ethylene-polymer, by extrusion-laminating the molten resin sheet 10 made of propylene-based polymer in order to mold a laminate B. The respective surfaces on the sides of the crosslinked foamed sheets 6 and 5 of both the laminates A and B are arranged face to face so as to be fixed by pressure with pressing rollers 17 and 17 while being melted with a hot melting means 16 in order to form a laminated material C.

摘要： PURPOSE:To decrease the heat shrinkage factor at molding under heat so as to obtain stable and sure moldability by a method wherein a strain-free skin layer is formed on the surface of a crosslinked foamed sheet by extrusion laminating method and at the same time crosslinked foamed sheets are laminated to each other by piling them up. CONSTITUTION:A non-intumescent skin layer 3 is laminated to one side 6a of a crosslinked foamed sheet 6, which consists of propylene-based polymer and ethylene- based polymer, by extrusion-laminating a molten resin sheet 10 made of propylene- based polymer. Simultaneously, a decorative skin layer 4 is fixed by pressure to the skin layer 3 and cooled in order to mold a first laminate A with triple layer structure. A non-intumescent skin layer 2 is laminated to one side 5a of a crosslinked foamed sheet 5, which consists of propylene-based polymer and ethylene-based polymer, by extrusion-laminating the molten resin sheet 10 made of propylene-based polymer in order to mold a second laminate B. The respective surfaces on the sides of the crosslinked foamed sheets 6 and 5 of the laminates A and B are arranged face to face so as to be fixed by pressure while being melted by heating in order to form a laminated material C. At this time, a heat fusion layer 7 is formed at the pressure fixing portion. Finally, the laminated material is cut in lengths.

摘要： PROBLEM TO BE SOLVED: To reduce the working time in a piping work by providing an electric fusion socket integrally to a branch pipe side. SOLUTION: In a thermoplastic resin electric fusion saddle coupling (EF saddle coupling), for example, electric heating bodies 12 and 15 are housed at the inner side of a saddle 11 and a branch 13 respectively. When a branch pipe is picked out from a main pipe by using the EF saddle coupling, at first the EF saddle coupling is loaded on the main pipe whose surface is scraped, a power is fed to the electric heating body 12 at the saddle side from a terminal pin 14 so as to heat it, and the main pipe and the EF saddle coupling are thermal fused. Then, after a drill is inserted in the branch 13 to bore a hole to the main pipe, the drill is pulled out, the branch pipe whose surface is scraped is inserted to the branch 13, the power is fed to the terminal pin 14 at the branch 13 side of the EF saddle coupling, so as to heat the electric heating body 15, and the branch pipe is thermal fused to the branch 13.

摘要： PURPOSE:To make one kind of universal S-shape pipe adaptable to various construction demands by making a center short pipe and both lateral short pipes connectable in the freely changed state of the axial direction of the pipes. CONSTITUTION:A left short pipe 2 and a right short pipe 3 are respectively connected to the left side and right side of a center short pipe 4. In this case, the connection between the left short pipe 2 and the center short pipe 4 and between the center short pipe 4 and the right short pipe 3 is of such structure as to be able to change the axial direction of the pipes. The pipe axes of the left short pipe 2 and right short pipe 3 are changed respectively to the opposite sides in relation to the center short pipe 4 to obtain a universal S-shape pipe 1. In addition, the distance between the pipe axes of both left and right short pipes 2, 3 is freely changed by changing the degree of changing the pipe axes. This universal S-shape pipe 1 can be therefore adapted to various construction demands without needing to prepare various kinds of S-shape pipes.

摘要： PURPOSE:To facilitate shortening of joining operation and preventing a reinforced resin layer from being cut too deep by a method wherein the reinforced resin layer and a synthetic resin pipe are longitudinally shifted to expose an end part of the resin pipe easily by a method wherein a release layer is provided onto an interface between a synthetic resin pipe material and the reinforced resin layer on its outer peripheral side. CONSTITUTION:In a resin composite pipe 1, a grease layer 3 as a release layer is provided on a surface of a synthetic resin pipe (rigid vinyl chloride pipe) 2, and a longitudinally reinforced layer 4 of a fiber reinforced resin and its peripherally reinforced layer 5 are provided. For a separating method, a cutting line is sawed in the fiber reinforced resin layer surrounding an outer periphery of the synthetic resin pipe with a saw or the like. After dividing the fiber reinforced resin layer to be peeled off on a joining end side, the divided part is extracted to be peeled off. Consequently, a joining operation can be extremely shortened, and the fiber reinforced resin layer to be peeled off from the synthetic resin pipe 2 can be peeled off at once without breaking it into pieces. Therefore, its peeling operation can be surely carried out without leaving resides of a fiber or the like on the surface of the synthetic resin pipe 2.
