ム印刷機のジグザグ折り装置。 A housing is attached to the lower part of a pair of folding arms whose upper parts are pivotally supported and which swing back and forth from side to side around this axis. A pair of paper feed rolls are rotatably provided between the housings, and a pair of paper feed rolls are rotatably provided between the two housings, with the contact points of their circumferential surfaces substantially coinciding with the central axis of the housing. A swing lever is provided integrally with this housing so as to be able to swing back and forth to the left and right about the central axis of the housing as a fulcrum, and a driven vehicle is attached to a folding arm provided with the other housing, and the center of rotation of this driven vehicle is The driven vehicle is provided with an internal gear, and one of the paper feed rolls is provided with a gear that meshes with the internal gear.
A zigzag folding device for a form printing press, characterized in that a driving wheel for driving the driven wheel is provided on the swing center axis of the folding arm.
