PURPOSE:To certainly and rapidly correct the shift of a printing surface and a processing position, by arranging an adjustment part, which adjusts feed tension while changes the same on the basis of the output of a tension detector, behind the processing part for applying the processing a folding perforation to a material to be printed. CONSTITUTION:The material 1 to be printed sent out from a wind-up body 1 is sent by a first dancer roller 5 through a guide roller 4 to receive rough adjustment and passes a first feed roller 16, a second dancer roller 7, a guide roller 8, a printing part 9, a first tension detector 12, a second feed roller 15, a superposition part 17, a second tension detector 20, a post-processing part 18 applying a folding perforation and the nip between a third feed roller 19 and a nip roller 21. A fluid control part 13 displaces the second dancer roller 7 in a movable state through an operator 14 corresponding to the output of a first tension detector 12 to perform the fine adjustment of feed tension. A fluid control part 22 changes the contact pressure with the material 1 to be printed through an operator 23 and the nip roller 21 corresponding to the output of the second tension detector 20 and controls tension to correct the deviation of a printing surface and a processing position. |
