Abstract
The invention concerns a continuous rotary apparatus for blow-moulding plastic hollow bodies in which the height of the moulds may be easily changed and which permits a minimum of waste plastic material. This apparatus comprises a fixed framework equipped with a fixed track which carries a plurality of independent moulding units travelling over the track and equipped with a driving device and a device for driving the moulding units which comprises a rotary platen mounted on a shaft which can be moved relative to the fixed framework and is equipped with equidistant slots which act on the driving devices of the moulding units. When the height of the moulds of the moulding units are changed the shaft carrying the rotary platen is displaced relatively to the fixed framework in such a manner that when a mould is in position to be fed with a portion of a continuous hot parison, the preceding mould still fed with a portion of parison is temporarily in contact with it.
