Described is a corrugator device for shaping thermoplastic corrugated pipes out of a molten plastic tube issuing from an extrusion device comprising moving molding jaws 1.1 through 1.6 which circulate in a linear molding section 10 and arranged in paired successive relationship in the molding section 10 form a molding passage, wherein the pairs of molding jaws are formed from left-hand and right-hand molding jaws 1,1 through 1.6 and between them enclose a cylindrical mold cavity to form the molding passage, and a gripper device 2 for guiding the molding jaws 1.1 through 1.6 from the end of the molding section 10 back to the start of the molding section 10. The gripper device has a gripper 2 for the left-hand molding jaws and a gripper 2 for the right-hand molding jaws with a guide and drive device. The guide and drive device has a linear guide rail X1 extending in the X-direction and a linear guide rail Y1 extending in the Y-direction, which are each in the form of respective separate rail devices. The gripper 2 is displaceable on the Y-rail Y1, and the Y-rail Y1 is displaceable on the X-rail X1,
