Device for the production of transversely ribbed pipes

An apparatus for the production of transversely ribbed tubes, comprising:

• mold jaw halves which are circulatingly movable in a condition of bearing against each other along two guide paths by means of a respective associated drive device, wherein the two guide paths have a common mold section, a respective return section and two respective direction-changing sections, wherein the respective direction-changing section has a direction-changing member provided with an arcuate guide edge for the mold jaw halves:
• wherein the respective direction-changing member comprises a low-wear plastic material and is linearly movably guidedly arranged on a base element fixed with respect to the machine and is connected to a compensating device which is compensating for a tolerance play, which is dependent on the temperature and/or the speed of the mold jaw halves, which circulate along the associated guide path wherein the respective direction-changing member is provided with a clothold-like guide edge for the associated mold jaw halves.
