PROBLEM TO BE SOLVED: To efficiently fold a sheet or a sheet stack.SOLUTION: A device for folding a sheet or a sheet stack 4 includes at least two folding/transfer rollers 1, a transfer device, and a cutter 2. The transfer device defines a transfer plane E for the sheet or the sheet stack fed in a transferring direction R, the cutter 2 is movable substantially vertically to or through the transfer plane E, the folding/transfer rollers are arranged to face both sides of the cutter above the transfer plane E, the rotary axis A of the folding/transfer roller extends substantially vertically to the transfer plane E, the ends of at least the two folding/transfer rollers have chamfered parts, and the sheet or the sheet stack can be inserted into a narrow gap between at least the two folding/transfer rollers by the cutter so as to be folded therein and simultaneously discharged in the transferring direction R.SELECTED DRAWING: Figure 2b |
