Abstract: A header pipe for an automobile coolant condenser having a W-shaped profile in longitudinal cross section such that the projecting portions of the profile makes two-point contact with the ends of the corrugated fins.

Abstract: A method of winding a reinforcement layer of a pneumatic radial tire, which comprises providing at circumferentially spaced locations opposite to a front face of an outer peripheral surface of a building drum, a pair of traverse devices each having a fiber cord feed guide and constructed so as to be reciprocated along the axial direction of the building drum; and moving the pair of traverse devices by independent driving devices along the axial direction of the building drum while rotating the building drum, thereby simultaneously feeding rubberized fiber cords respectively from each feed device to a reinforcement belt on the building drum.

Abstract: In a wiping apparatus for an intaglio printing press, a piston rod actuating end of a fluid pressure cylinder is pivotally coupled to each eccentric bearing for supporting the wiping roller, and the fluid pressure cylinder is supported by an adjusting mechanism for slightly moving in an extendable direction of the piston rod. A doctor blade holding member and a press-side support member are coupled by a plurality of fixing screws. The support member is reciprocally supported relative to the press side in an attachment/detachment direction of the doctor blade. The eccentric bearings and both ends of the support member are coupled by cam mechanisms for interlocking pivotal movement of the eccentric bearings with reciprocal movement of the support member. A doctor blade contact pressure fine-adjusting mechanism reciprocates the holding member with respect to the support member. Belleville springs are inserted between heads of fixing screws and the doctor blade holding member.

Abstract: Apparatus for arraying/conveying web-like workpieces such as unvulcanized treads delivered from an extruder. A plurality of forks sequentially lift the workpieces to and from roller conveyors and arrange the workpieces in selected uniform spaced-apart relation on a flat storage area.

Abstract: For joining pieces of rubberized tire cords or like sheet material end to end, a pair of coplanar tables are provided which have edges disposed opposite to each other in exact parallelism. Each table is equipped with a retractable stop for positioning a piece of sheet material thereon with its end projecting a predetermined distance beyond the said table edge, and a clamp for temporarily securing the sheet material in position on the table. As one of the tables is then moved toward the other, the pieces of sheet material have their opposed ends preliminarily joined together. The apparatus further comprises at least one finishing roller supported above the tables for rolling the preliminarily formed joint of the sheet material, which roller is in the form of a coil of wire effective both to smooth and to strengthen the joint.

Abstract: Rubber cloth splicing apparatus broadly comprising a forward vibrating conveyor, a butt-splicer, a backward vibrating conveyor, and a take-up conveyor. Each piece of rubber cloth is fed by the forward vibrating conveyor onto the rear table of the butt-splicer and is clamped in position thereon, whereas the precedingly spliced rubber cloth piece is fed backwardly by the backward vibrating conveyor onto the front table of the butt-splicer and is similarly clamped in position thereon. The two rubber cloth pieces are joined end to end without overlap as the rear table is forced into abutting contact with the front table. The take-up conveyor carries the spliced pieces of rubber cloth away from the butt-splicer via the backward vibrating conveyor by indexed movement.
