Apparatus for intermittently feeding continuous paper in a printing press

An apparatus for intermittently feeding continuous paper to be employed in a printing press for making an impression cylinder in contact with/separated from an oppositely rotating transfer cylinder at prescribed timing by contact/separation means to intermittently feed said continuous paper inserted between said impression cylinder and said transfer cylinder in association with said timing thereby to perform printing on said continuous paper, said apparatus comprising:

• paper feeding means arranged on an inlet side of a printing position for forward/reverse feeding and stopping said continuous paper at timing previously set in relation to said timing for contact/separation;
• and
• a suction conveyer arranged in an outlet side of said printing position for sucking and conveying printed said continuous paper to a discharge side while switching its suction force in plural stages in relation to said paper feed timing.
