ABSTRACT:
A device for heating parisons made of a thermoplastic material and having a supporting ring for blow molding hollow bodies, having a conveyor means, a plurality of holding means which are arranged on the conveyor means and grip the head area of the parisons between the supporting ring and the mouth and radiant heaters arranged on the path of movement of the parisons carried by the holding means, a shield supported by the conveying means being assigned to each holding mandrel in the form of a cover plate which is located at the height of the supporting ring and has a borehole to receive the supporting ring. Furthermore, there is also a cooling device, which acts directly on the exposed head area. This permits optimum protection of the head area of the parisons, which is not to be shaped or deformed, to prevent unacceptable heating.
