Abstract
A cutting device has a transportation railway for guiding a pile of sheets, a cutter positioned along the transportation railway for cutting a pile of sheets delivered thereto into a plurality of smaller sheets; a first pusher movable along the railway by an operating device from a primary delivery starting position to a primary delivery completion position and engageable with a pile of sheets to be cut for intermittently moving a part of the length of the pile of sheets in the direction of the railway past the cutter where the pile of sheets is cut into piles of smaller sheets. Upon the first pusher reaching the primary delivery completion position, it is retracted to the primary delivery starting position for engagement with a succeeding pile of sheets for moving the succeeding pile of sheets toward the cutter. A second pusher is movable along the transportation railway by an operating device from a secondary delivery starting position coincident with the primary delivery completion position and to a secondary delivery completion position adjacent the cutter and engageable with the firstmentioned pile of sheets for intermittently moving the remainder of the length of the firstmen…
