Problems solved by technology

[0010] A controllable clamping element is already described in DE 10 2005 011 805, which is made of an elastomer material and is configured as a spring-like hollow profile, whereby, compared to a solid profile, for example in the form of an O-ring, although Significant improvements have been achieved, but the requirement for uniform and reproducible unrolling over long runtimes is still not met in a satisfactory manner and method

Embodiment Construction

[0042] exist figure 1 and 2 The schematic structure of a device for forming a preform 1 into a container 2 is shown in FIG. The arrangement here can take place as shown or rotated by 180° in a vertical plane.

[0043]The device for shaping the container 2 basically comprises a blow molding station 3 provided with a blow mold 4 into which the preform 1 can be inserted. The preform 1 can be an injection molded part made of polyethylene terephthalate. In order to allow the introduction of the preform 1 into the blow mold 4 and to allow the removal of the finished container 2, the blow mold 4 consists of mold halves 5, 6 and a bottom part 7 which can be lifted by a lifting device. 8 positioning. The preform 1 can be held in the region of the blow molding station 3 by a holding element 9 . It is also possible, for example, to insert the preform 1 directly into the blow mold 4 , for example by means of clamps or another operating mechanism.

Abstract

The device is for blow moulding containers. Parisons made from a thermoplastic material are heated in the region of a heating path and then transferred to a blowing device. The blowing device is provided with at least one blowing station for moulding the parisons into the containers. The parisons are supported by a support element along at least a part of the transport path thereof, which is at least partly loosely introduced into a mouth section (21) of the parison and after introduction clamped within the mouth section. The clamp element (57) has a round embodiment. At least two clamp elements are arranged at a separation from each other along an outer circumference of the head.

Description

technical field [0001] The invention relates to a device for blow molding containers, which device has a heating section for heating preforms made of thermoplastic material and is provided with a blow molding device with at least one for Blow molding station for forming the preforms into containers, and in this device a carrier element for conveying the preforms in the region of the head which can be inserted into the mouth section of the preforms There is at least one positionable clamping element. Background technique [0002] When forming containers by means of blow molding pressure, preforms made of thermoplastic material, for example PET (polyethylene terephthalate), are fed to different workstation. Typically, such a blow molding machine has a heating device and a blow molding device, in the region of which the previously temperature-treated preform is expanded by biaxial orientation to form the container. The expansion takes place by means of compressed air which i...
