Abstract
A corrugator device for shaping thermoplastic corrugated pipes out of a molten plastic tube issuing from an extrusion device may include moving molding jaws which circulate in a linear molding section and are arranged in paired successive relationship in the molding section forming a molding passage. The pairs of molding jaws may be formed from left-hand and right-hand molding jaws and between them enclose a cylindrical mold cavity to form the molding passage. The device may include a gripper device for guiding the molding jaws from the end of the molding section back to the start of the molding section, and having grippers respectively for the left-hand and the right-hand molding jaws, each with a separate guide and drive device.
