Abstract

There is described an apparatus (10) which is provided for the production of tubes with a transversely profiled wall. The apparatus (10) has shaping halves (16, 30) which move along two paths (14) closed in themselves and form a common shaping section (18) and two return sections (20). Provided at each of the two return sections (20) is a respective turning device (26) at which two shaping halves (16, 30) are disposed by means of a holding and release device (32). The one shaping half (30) has a socket contour in order to be able to produce transversely profiled tubes with sockets, with the apparatus (10).
