Abstract

A method of conveying plastics material pre-forms includes the plastics material pre-forms supplied to a conveying device by a supply device. The conveying device has a first roller body and a second roller body. The plastics material pre-form is conveyed between these roller bodies. A portion of the plastics material pre-forms is supported by the two roller bodies. A further portion of the plastics material pre-forms passes through between the roller bodies. At least one first value characteristic of a state of occupation of the plastics material pre-forms is detected by a first measuring instrument. A second value characteristic is detected by a second measuring instrument downstream of the first measuring instrument in the conveying direction of the plastics material pre-forms. A setting variable of the supply device or the conveying device is controlled on the basis of the two values.
