ABSTRACT:
A system for controlling a dump gate in a conveyor system (e.g. carrying printed copy from a high-speed printing press to stackers) detects a marker carried by a marred product (e.g. a metal tab fitted when splicing a new reel of paper) to start a counter which counts the products passing and opens the dump gate a predetermined count. A counter closes the dump gate again when a second predetermined count of passing products is reached.
