Abstract
A paper web folding and cutting apparatus for a form printing machine includes a paper web traveling path which enables a continuous paper web to travel at a predetermined traveling speed. A cut portion forming device is disposed on the paper web traveling path and is adapted to form a cut portion formed in a line of a plurality of cuts. Each line of the cuts has at least one uncut portion, at every top and bottom directional dimension of the continuous paper web to be folded. Also, an oscillatory shooter assembly is disposed on the paper web traveling path on a downstream side of the cut forming means in a paper web traveling direction. The oscillatory shooter assembly is provided with a counter roller and a nozzle roller at a lower end portion thereof. The rollers are rotated at a peripheral speed which is faster than the paper web traveling speed, and the nozzle roller is movable into and out of contact with the counter roller. The oscillatory shooter assembly performs an oscillatory motion in a bilateral direction with the continuous paper web interposed between the nozzle roller and the counter roller so as to fold, in a zigzag fashion, the continuous paper web along the cut portions. According to this structure, the continuous paper web is cut along the cut portions by pressing the nozzle roller against the counter roller at a timing when the cut portion to be cut approaches an upstream side portion of both the nozzle roller and the counter roller.
