摘要： A paper-web holding apparatus is provided in a rotary printing press having rollers which form a path for a paper web fed from a paper web feeding unit to travel along to a folding unit via a press unit and around which the paper web is wrapped. The paper-web holding apparatus includes a rotation restraint mechanism provided for at least one selected roller, and a propeller roller mechanism provided for the selected roller. The rotation restraint mechanism restrain rotation of the roller when the rotary printing press is halted, and allows rotation of the roller when the rotary printing press is operated. The propeller roller mechanism has a pressing member which is advanced toward the roller in order to apply pressing force to the roller at least when the rotary printing press is in a halt state.
