Abstract
With a sheet stacker to stack sheets cut by a sheet cutter into stacking station, sheets cut by a sheet cutter are transferred by a conveyor with a fixed sheet interval, a clamping device clamps a base position near the tail end of the sheet during transfer of the sheet, and the sheet transfer speed is reduced to an optimum speed needed for stacking the sheet into stacking station orderly. The clamping device has a rotating device having free rolls at its end and a slowdown roll, and clamps the sheet once during each revolution of the rotating device, by contact of the free rolls with the slowdown rolls.
