Abstract
The method and the device serve for the blow moulding of containers (2). Preforms (1) of a thermoplastic material are heated in the region of a heating path (24) and then transferred to a blowing device (25). The blowing device (25) is provided with at least one blowing station (3) for moulding the preforms (1) into the containers. The preforms (1) are retained along at least a section of the transport path thereof by a support element (46) which is at least partly loosely introduced into a mouth section (21) of the preform (1) and tightened in the mouth section (21) after the introduction thereof.
Claims22
A method for blow molding containers, in which preforms made of a thermoplastic material are heated in a heating line and then transferred to a blowing system, in which the preforms are shaped into containers by the action of blowing pressure inside blow molds, wherein the preforms (1) are held along at least a portion of their transport path by a support element (46), which is at least partly loosely inserted into a mouth section (21) of the preform (1) and, after it has been inserted, is tightened inside the mouth section (21).
A device for blow molding containers, which has a heating line for heating preforms made of a thermoplastic material and a blowing system that has at least one blowing station for shaping the preforms into containers, wherein a support element (46) for transporting the preforms (1) has at least one spreadable expanding element (57) in the area of a head (55) that can be inserted into a mouth section (21) of the preform (1).
