Abstract
A folding jaw cylinder for a printing press has a folding jaw arranged rotatably at the cylinder, a stop for the folding jaw, a rotary body, which can be nonrotatably connected to the cylinder, and whose angular position in relation to the cylinder is adjustable, and a gear mechanism for adjusting a working distance between the folding jaw and the stop by adjusting the angular position between the cylinder and the rotary body. The stop is arranged movably at the cylinder, and is adjusted in relation to the cylinder--during the adjustment of the angular position between the cylinder and the rotary body--by an adjusting arrangement, which is articulated to the rotary body and attached to the stop.
Claims21
A folding apparatus for a printing press, the apparatus comprising:
- a folding cylinder rotatably mounted in the press;
- a folding jaw positioned on said folding cylinder;
- a stop positioned on said folding cylinder for cooperating with said folding jaw to grip a fold, said stop having structure for being pivotally mounted on said folding cylinder about a jaw axis substantially parallel and eccentric to an axis of rotation of said folding cylinder;
- clamping means for moving said folding jaw toward and away from said stop to grip and release a fold, said clamping means moves said folding jaw with respect to said folding cylinder to move said folding jaw toward and away from said stop, said clamping means moving said folding jaw at specific angular positions of said folding cylinder with respect to the printing press;
- a rotary body rotatably connected to said folding cylinder;
- adjusting means for adjusting a working distance between said folding jaw and said stop depending on an angular position of said rotary body with respect to said folding cylinder, said adjusting means moves said stop toward and away from said folding jaw with respect to said cylinder to adjust said working distance, said working distance being a distance between said folding jaw and said stop when said clamping means is not gripping a fold;
- angular position means for varying an angular position of said rotary body with respect to said folding cylinder.
