Abstract
Sheets of cardboard continuously fed in a shingled stream are stacked upon a progressively lowered speed form until the desired stack height is reached, whereupon a vertically-fixed horizontal movable bar grate is inserted between the oncoming sheets and the finished stack, concurrently with vibration of the stop board against which the leading edges of the sheets impact.
