PROBLEM TO BE SOLVED: To continuously produce a unit printed paper sheet that has no margins in the front part and the rear part under the transfer of the continuous printing paper. SOLUTION: A front part and a rear part rotary cutters 2, 3 are arranged in parallel on continuous printing paper 1 on which multiple unit print A is made through a margin B at almost equal intervals as a transfer size L1 of the unit print A. A transfer quantity L3 of the continuous printing paper 1 during both rotary cutters 2, 3 make one turn, is set on the transfer quantity of the transfer direction size L1 of the unit print A to which the transfer direction size L2 of the front part margin B is added. By this transfer, the front part margin B of the forward unit print A of the continuous printing paper 1 is protruded forward from the cutting line of the front part rotary cutter 2. Then, the front margin B is cut along the forward edge of the forward unit print A by the front part rotary cutter 2 and is removed. Almost at the same time, the latter margin B is cut along the rear edge of the forward unit print A by the rear part rotary cutter 3, to obtain a unit print paper sheet A' that has no margin B in the front part and the rear part.
