ABSTRACT:
The blowing wheel and preferably the heating wheel as well as a large blow molding machine are rotatably supported in a centerfree peripheral bearing means. The heating and blow wheels are constructed as wheel rings to provide a profile free of distortion, wobbling motions or, respectively, peripheral vertical deviations of the wheels are thus prevented and the delivery of parisons of thermoplastic material for processing on the wheels takes place with high accuracy.
