CORRUGATOR DEVICE WITH SPECIFIC GUIDANCE OF THE COOLING AIR CIRCUIT

摘要

A corrugator device for shaping a corrugated pipe R from a tube of molten plastics material S is described. 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.
