An apparatus for heating plastics material pre-forms includes a conveying device which conveys the plastics material pre-forms along a pre-set conveying path (P). A plurality of holding elements for holding the plastics material pre-forms and a plurality of screening elements for screening off heat are arranged on the conveying device. The apparatus has a plurality of carrier units on which at least parts of the holding elements and at least parts of the screening elements are arranged and these carrier units are capable of being removed from the conveying device jointly with the parts of the holding elements and screening elements which are arranged thereon.
Description
technical field [0001] The invention relates to a device and method for heating plastic parisons. In the field of the plastics processing industry and in particular the beverage production industry, it has long been known to form plastic bottles from plastic parisons by blow molding. In this case, the plastic parisons are first heated in a heating device and the plastic parisons are then expanded in the expanded state. Background technique [0002] Many different heating devices are known from the prior art. In this way, for example, infrared ovens are known, as well as microwave ovens, through which the plastic parisons are conveyed. In the case of a heating device of this type, several carriers for the individual plastic parisons are arranged behind each other on the main carrier. In this case, a small gap is required between the differently adjoining plastic parisons. [0003] In addition, devices of this type usually also have barrier elements which protect the holes...
