し機構。。A paper peeling mechanism for a rotary printing press, in which a paper peeling claw is brought into contact with a printing base paper mounted on a screen to peel off a feed-side light end of the printing paper adhered to the printing base paper from the printing base paper. , a paper ejection roller which is arranged parallel to the print drum on the print paper ejection side of the print drum that drives the screen, and which has a circumferential speed larger than the circumferential speed of the print drum; There are paper j''% stiff claws that swing in synchronization with the rotation of the printing drum and come into contact with the printing base paper at a timing before the leading end of the printing paper is ejected from the printing drum, and protrusions at regular intervals on the circumferential surface. and a free roller that presses against the paper ejection roller in response to the paper peeling claw, and applies tension when the leading edge of the printing paper is bitten by the free roller to separate the printing paper from the paper peeling claw. A paper peeling mechanism for a rotary printing press.
