Abstract

A device for forming containers from heated parisons of thermoplastic material, which includes a heating section and a blow molding unit provided with at least one blow molding station. The parisons are held along at least a portion of a transport path between the heating section and the blow molding unit by a carrying element, which has a head that can be inserted into a mouth section of a parison and which includes at least two positionable clamping elements. At least one of the clamping elements is positioned in a recess provided on a side of the head relative to a longitudinal axis of the carrying element. The recess has upper and lower sliding surfaces that extend obliquely relative to the longitudinal axis for acting on the clamping element. The upper head part and the lower head part are braced relative to each other by at least one spring.
