Embodiment Construction

[0034] figure 1 is a diagrammatic representation of an apparatus 1 according to the invention for forming plastics material pre-forms into plastics material containers. The apparatus 1 has a supply device, such as a transport star wheel 32 , which supplies the apparatus 1 with plastics material preforms. Furthermore, a heating device for heating the plastics material preforms can also be provided upstream of the apparatus 1 in the conveying direction of the plastics material preforms. The device 1 has a carrier 2 , which is rotatable about an axis of rotation D, and on which a plurality of blow moulding stations 8 are arranged. The plastics material pre-forms 10 are formed into plastics material containers 10a by means of these blowing stations 8 in each case. The plastic material container produced in this way is removed by means of the removal wheel 34 .

Abstract

The method involves placing a plastic preform (10) into a blow mold. The blow mold with the plastic preform is transported along a predetermined transport path (Tp). The plastic preform is pressurized with a gaseous medium for a predetermined period during expansion. The supply of the gaseous medium is controlled. The receptacle (10a) is depressurized at a predetermined time (t2) which is altered. An independent claim is included for a device for molding plastic preforms into plastic containers.

Description

technical field [0001] The invention relates to a method and a device for forming plastics material pre-forms into plastics material containers. Machines of this type, hereinafter referred to as blow molding machines, have long been known from the prior art. In this case, the plastics material pre-forms are usually transferred to a blow molding station and this blow molding station is arranged on a movable carrier, for example a rotatable blow molding wheel. During transport of the plastics material pre-forms inside the blow molding station, the plastics material pre-forms are blown or inflated by applying compressed air to the plastics material pre-forms in order to form the plastics material containers. For this purpose, the plastics material pre-forms are acted on at very high pressures (eg more than 40 bar). Background technique [0002] It is also known from the prior art that blow molds or their carriers of this type lock to each other during the expansion process. ...
