Paper web folding and cutting apparatus

A form printing press having 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 every top and bottom of each portion of the continuous paper web to be folded, wherein said cutting assembly operates continuously as the continuous paper web travels along the paper web traveling path;
• 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 countermand 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 as the continuous paper web is interposed between said nozzle roller and said counter roller so as to fold the continuous paper web in a zigzag fashion along the cut lines formed by said cutting assembly so that each fold coincides with one of the cut lines,
• wherein the continuous paper web is cut along the cut lines by moving the nozzle roller into contact with the counter roller when one of the cut lines approaches an upstream side of said nozzle roller and said counter roller.

A form printing press having a paper web folding and cutting apparatus comprising:

• means for feeding a non-perforated continuous paper web along a paper web traveling path such that the continuous paper web travels 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 in the non-perforated continuous paper web, the line of cuts having at least one uncut portion, at every top and bottom of each portion of the continuous paper web to be folded, wherein said cutting assembly operates continuously as the continuous paper web travels along the paper web traveling path;
• a paper web guide assembly, disposed along the paper web traveling path immediately upstream of said cutting assembly, for guiding the non-perforated continuous web into said cutting assembly;
• 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 as the continuous paper web is interposed between said nozzle roller and said counter roller so as to fold the continuous paper web in a zigzag fashion along the cut lines formed by said cutting assembly so that each fold coincides with one of the cut lines,
• wherein the continuous paper web is cut along the cut lines by moving the nozzle roller into contact with the counter roller when one of the cut lines approaches an upstream side of said nozzle roller and said counter roller.
