Abstract: A method for transporting preforms in the area of a machine for blow-molding thermoplastic containers along a sorting device configured as a roll sorter. A sensor arranged at the sorting device senses a preform passing through its detection area and generates a sensor signal that transmitted to a control system, which evaluates the sensor signal and generates a control signal as a function thereof. A process parameter of the sorting device and/or of a conveying device upstream of and supplying preforms to the sorting device is adjusted as a function of at least one of the control signals. A sensor senses a section of the sorting device and generates a signal that contains data on a gap between a pair of preforms being transported successively passed this sensor. The control signals for adjusting a process parameter of the conveying device and/or of the sorting device are dependent on gap data.

Abstract: The device serves for blow molding containers. Preforms of a thermoplastic material are heated in the area of a heating section and are subsequently transferred to a blow device. The blow device is provided with at least one blow station for deforming the preforms into the containers. The preforms are held along at least a portion of their transport path by a support element which over at least portions is loosely inserted into an opening section of the preform and is tensioned after the insertion within the opening section. Along an outer circumference of the head are arranged at least two clamping elements at a distance relative to each other.
