PURPOSE:To eliminate the trouble of after processing by always starting to press a paper ending roll to a pasting position at a preset position, and regulating the overlapping length of old and new original paper. CONSTITUTION:After a paper ending command signal A is output, in T seconds after detecting the first pasting position, a start signal C for operating a paper ending roll is output, and a paper ending roll 4 is operated by an actuator or the like to be pressed to a symmetrical position separated from the pasting position by 180 deg.. Similarly, a cutter 13 is displaced at the point of time when a start signal D for operating the cutter is output extending over t2 hours to cut the trailing end of the old paper. This position is behind the paper ending roll 4 pressing position by t/2+t1, and the cutter operation time t2 is expressed by t2=(n+1)t+t1-P10. Thus, T+t0 seconds later behind the first pasting position, the paper ending roll 4 is started to press to a new original paper roll, and further t/2+t1 seconds later, the trailing end of the old paper is cut to regularize the over-lapping length of old and new original paper rolls. |
