The severed web is cut into box blanks which are transported on a stacker conveyor in shingled relation. The speed of the severed web through the corrugator is continuously controlled to prevent the gap from exceeding the limit when the gap reaches the stacker conveyor. Alternatively, the stacker conveyor is temporarily stopped until the size of the gap falls below the limit, and the stacker conveyor is re- started before the gap can close. In either case, the gap control prevents bumping of consecutive box blanks on the stacker conveyor following a change-over of production runs while insuring that the first blank of the new production run shingles on the last blank of the old production run with sufficient tail to insure retention of the first blank by stacker conveyor suction cups or tail grabbers.
