Abstract
A folding apparatus includes at least a first folding cylinder and a second, folding jaw cylinder. A third measuring cylinder is also provided. The measuring cylinder is usable to cut product sections or signatures of a determined length L from an endless web. The first cylinder is embodied, in one embodiment, as an engaging cylinder, and as a second embodiment as a puncture cylinder. In both embodiments, the product section or signatures which are produced, have the same length.
Claims23
1-25. (canceled)
A folding apparatus comprising:
- at least a first cylinder having a first circumferential speed;
- a second cylinder, embodied as a folding jaw cylinder and cooperating with said first cylinder;
- a cutter cylinder cooperating with said first cylinder and adapted to sever product sections of a defined length from a continuous web having a feeding speed corresponding to said first circumferential speed;
- a common frame supporting said first cylinder and said second cylinder as a first folding group;
- a seating arrangement of said first cylinder and said second cylinder in said frame, said seating arrangement being usable to support said first cylinder configured selectively as a gripper cylinder and a spur needle cylinder and having a drive geometry and a relative position between said first cylinder and said second cylinder whereby said product section has said defined length.
The folding apparatus of claim 25 further including a second folding group in said common frame, said first folding group being provided with said first cylinder as one of said gripper cylinder and said spur needle cylinder, said second folding group being provided with said first cylinder as the other of said gripper cylinder and said spur needle cylinder.
