Device for blow-moulding containers

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...
