Abstract:
A paper web folding and cutting apparatus comprising:a paper web traveling path along which a continuous paper web can travel at a predetermined traveling speed and in a paper web traveling direction; a cutting assembly disposed along the paper web traveling path and adapted to form a line of cuts, having at least one uncut portion, at the top and bottom of each portion of the continuous paper web to be folded; and an oscillatory shooter assembly disposed along the paper web traveling path, said oscillatory shooter assembly being located downstream of said cutting assembly with respect to the paper web traveling direction, said oscillatory shooter assembly including a counter roller and a nozzle roller disposed at a lower end portion of said oscillatory shooter assembly, said counter and nozzle rollers being rotatable at a peripheral speed that is faster than the paper web traveling speed, said nozzle roller being movable into contact with said counter roller and away from said counter roller so as to be separated therefrom, said oscillatory shooter assembly being capable of moving in an oscillatory motion with the continuous paper web interposed between said nozzle roller and said counter roller so as to fold the continuous paper web in a zigzag fashion along each of the lines of cuts formed by said cutting assembly so that each fold coincides with one of the lines of cuts, wherein the continuous paper web is cut along one of the lines of cuts by moving the nozzle roller into contact with the counter roller when the one cut line approaches the vicinity of an upstream side of said nozzle roller and said counter roller.
