Claim Text:
1. A method of treating plastics material pre-forms, comprising: conveying plastics material pre-forms by a conveying device; heating the plastics material pre-forms, during said conveying step, by a heating device; and treating the plastics material pre-forms, after said heating step, by a further treatment device in a further pre-set manner, the heating device and the further treatment device being operated in a synchronized manner at least for a time, wherein in the event of an error state occurring in said further treatment device downstream of the heating device, a supply of the plastics material pre-forms to the heating device is interrupted by a blocking device, discontinuing the synchronization such that no further plastics material pre-forms are conveyed to the heating device and no further plastics material pre-forms are conveyed between the heating device and the further treatment device, at least for a time, when the error state arises, wherein chronologically after the occurrence of the error state, a check of synchronization between the heating device and the further treatment device is performed by a regulating loop as to whether synchronization has taken place, whereupon, when the check indicates non-synchronization, the further treatment device is brought into synchronism again with the heating device during a pre-set synchronization period, and wherein the supply of the plastics material pre-forms to the heating device is permitted again, according to the check, during the synchronization period or at the start of the synchronization.
