摘要： The invention describes a corrugator device for shaping thermoplastic corrugated pipes out of a molten plastic tube which emerges from an extrusion device, comprising moulding jaws 1.1 to 1.6 which are guided so as to circulate in a linear moulding section 10 and are arranged in pairs one behind the other so as to form a moulding passage in the moulding section 10, wherein the pairs of moulding jaws are formed from left-hand and right-hand moulding jaws 1.1 to 1.6 and between them surround a cylindrical mould cavity in order to form the moulding passage, and comprising grippers 2 for guiding the moulding jaws 1.1 to 1.6 from the end of the moulding section 10 back to the start of the moulding section 10. A mould release device, which has at least one motor-driven rotary disc 3, is arranged at the end of the moulding section 10. The motor-driven rotary disc 3 has a first driver 31 and a second driver 32 which are arranged such that the distance between the first driver 31 and the central rotational axis of the rotary disc is smaller than the distance between the second driver 32 and the central rotational axis. As a result, at the beginning of the mould release operation, the first driver 31 acts on the moulding jaws with the smaller lever arm and then, during the mould release operation, the second driver 32 acts on the moulding jaws with the larger lever arm.

摘要： The invention relates to a facility (10) for manufacturing multilayered composite tubes (116). Said facility has (10) a metal strip unwinding device (44), a metal strip storing device (48) connected to the unwinding device (44), a metal strip shaping device (36) connected to the storing device (48), an extruder station (12) connected to the metal strip shaping device (36) and a cooling device (50) connected to the extruder station (12). The metal strip shaping device (36) is used to shape the metal strips (38) unwound by the unwinding device (44) into a metal tube with overlapping longitudinal edges, which are welded in a welding station (32) provided in the extruder station (12) to form the metal tube. The metal tube is adhesive coated with a plastic lining and a plastic coating in the extruder station (12). The composite tube thus manufactured is then cooled to ambient temperature in the cooling device (50).

摘要： The invention relates to a device for continuously producing seamless plastic tubes. According to the invention, a distribution plate (13a) is provided as a distribution element for the melted material to be fed to an annular gap. Said distribution plate is arranged inside the cross-section of the mold cavity. The melted plastic material is guided to the peripheral surface (24) of the distribution plate in a manner which is essentially radial with respect to the direction of production via distribution channels (14) which branch in a tree-like fashion. The flow path of the melted plastic material is the same in the individual distribution channels (14) between the entry opening (20) and the peripheral surface (24).

The corrugator device comprises movably driven molding jaws 1a, 1b with a corrugated molding area 1f. The molding jaws are formed as first and second molding jaws 1a, 1b, which form pairs of molding jaws 11. The corrugator device comprises a molding passage 10, which is formed by traveling pairs of molding jaws 11 arranged one behind the other. Further on the corrugator device comprises an air cooling device 15 for cooling the molding jaws 1a, 1b. It is provided that the air cooling device 15 has at least one first cooling air circuit 151 with a heat exchanger and a blower and at least one second cooling air circuit 152 with a heat exchanger and a blower. Thereby the at least one first cooling air circuit 151 is formed for cooling the first molding jaws 1a of the pairs of molding jaws 11 and the at least one second cooling air circuit 152 is formed for cooling the second molding jaws 1b of the pairs of molding jaws 11.
