    摘要： An apparatus for the manufacture of corrugated plastic pipes comprises half shells. Each half shell has a base body which consists of a metal of a higher thermal conductivity and a lower specific gravity than steel and which holds a core. Provided in the core is a mold recess in which to form the corrugated pipes.

    摘要： A twin-wall pipe comprises an internal pipe and an external pipe. The external pipe is corrugated, having elevations and troughs. The twin-wall pipe is further provided with a socket. In a transition portion towards the twin-wall pipe and the socket, provision is made for at least one overflow passage which interconnects the clearance between the external pipe and internal pipe in the vicinity of the transition portion and an adjacent elevation. a≧b refers to the radial height b of the overflow passage relative to its width a in the circumferential direction.

    摘要： An apparatus for the manufacture of compound pipes with an oval cross-section is equipped with mould halves which advance in a direction of production and of which two at a time combine as a pair on a moulding path to form one mould. An injection head of at least one extruder is arranged upstream of the moulding path. An external nozzle used for the creation of an external tube is substantially circular in shape and is located at a distance upstream of the moulding path. An internal nozzle with a cross-section similar to the oval cross-section of the pipe to be created is located inside the moulding path. When entering the moulding path, the external tube extruded through the external nozzle is expanded in one direction and pressed together in a direction which is perpendicular to the former.

    摘要： An apparatus for the manufacture of profiled plastic pipes comprises a machine bed (1) that half shells (2, 2′) are guided on, forming a molding path (9). A driving pinion (17) is provided above the molding path (9). At least one lower driving pinion (41) is provided on the machine bed (1) along the molding path (9). A lower indentation (39, 39′) is formed in the area of the lower side (30, 30′) of the half shells (2, 2′), with the at least one lower driving pinion (41, 41′) engaging therewith.

    摘要： A method and an apparatus for the manufacture of pipes of thermoplastics with transverse profile features comprises mold segment halves which are circulated by twos on a molding path. A conveying device of the type of a gantry crane is provided for recirculation of the mold segment halves. On a conveying bridge that bridges the molding path, provision is made for two conveying carriages, which are movable in opposite directions and cross-wise of the direction of production and which have mounted on them a downward conveying arm with a holding device for a respective mold segment half. Provided downstream of the downstream end of the molding path are parking positions for additional mold segment halves, those of which that are closest to the molding path being carriages which are movable out of the path of displacement of the conveying arms.
