Abstract

In a process for the production of hollow bodies from thermoplastic material by blow molding, an additional body is disposed inside the hollow body by being carried on a holding means which is joined to the inside surface of the wall of the hollow body. The additional body is disposed on the holding means at a spacing from the inside surface of the wall of the hollow body while that surface is subjected to a treatment with a treatment medium, so that the treatment medium has adequate access to the wall of the hollow body in the region of the additional body. After termination of the treatment the additional body is then moved on the holding means into a final position in which it is disposed at least closely adjacent to or in contact with the inside surface of the wall of the hollow body.
