Method for manipulating a product stream, in which the product stream is guided by means of conveying elements along a conveyor successively past a number of processing elements, said processing elements being controlled depending on a central control system for making the control elements operate in phase with the product stream, and for this purpose the central control system transmits control signals and receives detection signals on the position of the conveying elements, and in which according to the invention said central control system controls said control elements and also the conveying elements essentially independently of each other on the basis of an internal reference signal which is adapted, possibly temporarily, depending on detection signals coming from detectors if a certain preset threshold value is exceeded. <IMAGE>
