The invention relates a method for transporting preforms (18) in the area of a machine (14) for blow-molding thermoplastic containers along a sorting device (12) configured as a roll conveyor (28) with two rotating, in particular counter-rotating. At least a sensor (20) arranged at the area of the sorting device (12) senses at least one preforms (18) passing through its detection area of the sensor through a sensing technology and generates a sensor signal, wherein the sensor signal is transmitted to a control device (26) for processing; the control device (26) evaluates the sensor signal and generates at least a control signal according to the sensor signal; at least one of the control signals adjusts a process parameter of the sorting device (12) and/or a process parameter of a conveying device upstream of the sorting device (12); the conveying device is used for conveying the performs (18) to the sorting device (12); at least one of the sensors (20) senses path area of the sorting device (12) through the sensing technology; the sensing signals of the sensors (20) include at least the information of at least a gap between a pair of performs (18) being transported successively passed the detection area of the sensor (20); and the control signals for adjusting the process parameter of the conveying device (10) and/or of the sorting device (12) are at least dependent on the detected gap information.
