A method for coordinating the rate of processing of a container at a processing station with the rate of feed of said container to and removal from said processing station, comprising selecting a predetermined rate for said processing and said feed and removal, independently and continuously comparing the actual processing rate with said selected rate, independently and continuously comparing the actual feed and removal rate with said selected rate, and independently adjusting the actual rate of processing and the actual rate of feed and removal as needed to arrive at said selected rate. A corresponding apparatus is described wherein the speed selecting means includes a potentiometer. A pair of tachogenerators respond independently to the actual speeds of processing and conveying and these are independently electronically compared with the selected speed established by the potentiometer, the driving speeds being independently adjusted as needed in response to the comparisons.
