PURPOSE:To eliminate any slack of lowermost running paper as well as to improve the printing quality of another running paper by guiding only the lowermost running paper keeping in contact with a drag roller directly at the upstream side, and installing a tension increment adjusting guide roller for increasing a contact angle to the drag roller. CONSTITUTION:Only lowermost running paper (a) directly keeping in contact with a drag roller 1 is guide by a tension increment adjusting guide roller 4 at the upstream side, while a contact angle of the lowermost running paper (a) to this drag roller 1 is adjusted for increment, and tension of the lowermost running paper (a) is incleasingly tensed to that of other running paper sheets (b)-(e). In consequence, any drop in the printing quality of the lowermost running paper (a) and occurrence of rumples are all preventable. |
