摘要： PROBLEM TO BE SOLVED: To provide an efficient method for manufacturing a joint boot of a resin having a large-diameter opening part of high dimensional precision, by stepping up a molding cycle by reduction of the number of processes, deletion of surplus time and labor and shortening of a cooling time.
SOLUTION: First, the large-diameter opening part 3 in one end of a bellows-shaped hollow part 2 is injection-molded by injecting a molten resin 5 into a cavity 11 of a drawing-out device 9 from an outlet gap 6 of an annular orifice nozzle 7 through a conically annular passage 14 formed by an auxiliary nozzle mouthpiece 8. Then, a tubular parison 15 is drawn out and formed by moving the drawing-out device 9 and subsequently the bellows-shaped hollow part 2 and a small-diameter opening part 4 in the other end thereof are blow-molded integrally by using a blow molding split mold 10.

摘要： PROBLEM TO BE SOLVED: To provide a method and a device for producing a cylindrical rubber product having a bellows part, capable of automatically releasing the cylindrical rubber product from a mold without manual work by a worker.
SOLUTION: The method for producing a cylindrical rubber product 1 having an opening at both the opposite ends and a bellows part 4 in the middle comprises a step for injecting a rubber material into a molding space formed by a left mold 25, a right mold 26 and a core 27 to cure the material, a step for separating the left mold 25, the right mold 26 and the core 27 from each other, and a step for separating the upper end side outer peripheral face of the core 27 from the upper end side inner peripheral face of the cylindrical rubber product 1, while tilting and deforming the upper end side of the cylindrical rubber product 1 by means of an engaging member 54 arranged in the middle of elevation in which the core 27 stuck with the cylindrical rubber product 1 is elevated with an elevation device 37, and pulling out the core from the cylindrical rubber product 1, while injecting a compressed air into the inside of the cylindrical rubber product 1 from the separated position.

摘要： The present invention resides in a boot seal for use in sealing a joint. The joint comprises first and second relatively movable parts. The boot seal is configured in the form of a sleeve to extend between and around the vehicle relatively movable parts. The sleeve has a laminate wall which comprises at least two layers of thermoplastic elastomeric material which are bonded together. At least one of the layers is a stretch-toughenable polyester thermoplastic elastomer which has been diametrically stretched in an amount effective to increase the toughness of said one layer. The laminate wall has a percent elongation to rupture of at least 100, and a flexural modulus which is less than 100,000 psi. The laminate wall preferably has a puncture resistance of at least 50 Newtons/mm wall thickness.

摘要： PROBLEM TO BE SOLVED: To provide a corrugated tube for vehicle piping, which excels in flexibility and extensibility. SOLUTION: The corrugated tube 1 is constructed of a corrugated portion 5 formed by successively providing a plurality of annular protrusions 3 in an axial direction, and tubular portions 7, 9 integrally formed on axially opposite sides of the corrugated portion 5 and extending straight. The corrugated portion 5 is constructed with a corrugate pitch, which is an axial interval between tops of adjacent annular protrusions 3, being set at 2 mm and with a corrugate height, which is a radial distance between the top and a bottom of the annular protrusion 3, being set at 4 mm.

摘要： PROBLEM TO BE SOLVED: To increase a sealability at connection positions on a large resin pipe. SOLUTION: In this method for sealing a large resin pipe, the large resin pipes provided by continuously forming angle ribs in spiral shape are butted against each other, and the connection flanges at both ends of the band are connected to each other to tighten the band so as to connect the joint of the large resin pipes with the band. Caulking material is applied to the corners of a valley between the angle ribs when filling member is filled along the valley between the angle ribs located at the position narrower than the effective width of the band. A substrate foam sheet formed of soft foam material with closed cells having an inner surface coated with glue is stuck along the shape of the valley. The caulking material is applied to the upper surface of the foam sheet, the filling material is filled, and the caulking material is inserted in a clearance between the substrate foam sheet and the filling member. Then the foam sheet having an inner surface coated with glue is wound on the connection positions of the resin pipe so as to cover the filling member, and the connection position of the resin pipes is lapped and band-connected.

摘要： PROBLEM TO BE SOLVED: To optionally mold a considerably large pipe section which is out of standard pipes, and cannot be molded by a pair of die segment half bodies. SOLUTION: In this device for the manufacture of the thermoplastic pipe (68) which has the peculiar property on the lateral contour, die segment half bodies (4 and 5) which circulate by two units on a molding path (2) are provided. A bridge-form crane type carrying device (29) is provided for the circulation of the die segment half bodies. On a carrying bridge (34) over the molding path, two units of carrying carriages (44 and 45), which are movable in the lateral direction to the manufacturing direction while being confronted to each other, are provided. Then, a carrying arm (53) on the downstream side having holding devices (54) for respective die segment half bodies, which are attached to the carrying carriages (44 and 45), is provided. Stand by locations (77, 78 and 79) for auxiliary die segment half bodies (4a, 5a, 4b, 5b, 4c and 5c) are provided on the downstream side of the downstream end of the molding path. Then, carriages (81 and 82) which move by projecting from the moving path (85) of the carrying arm come closest to the molding path.
