Folder with group jaw adjustment
View Patent ↗A folder includes a collect cylinder having at least one gripper for receiving signatures, and at least one first tucker and a jaw cylinder having at least one first jaw for interacting with the first tucker, the at least one first jaw including a stationary jaw part and a movable jaw part, the stationary jaw part and the movable jaw part being settable independently with respect to the first tucker.
1. A method for adjusting a printing press comprising the steps of:
adjusting a stationary jaw part of a first jaw with respect to a first tucker of a collect cylinder; and
independently adjusting the distance between a movable jaw part and the first tucker for a tucking operation;
wherein the adjusting of the stationary jaw part step also causes the movable jaw part to move with respect to the first tucker.
2. The method as recited in claim 1 further comprising adjusting a second fixed jaw part of a second jaw with respect to a second tucker of a delta/double parallel cylinder.
3. A method for adjusting a printing press comprising the steps of:
adjusting a stationary jaw part of a first jaw with respect to a first tucker of a collect cylinder;
independently adjusting the distance between a movable jaw part and the first tucker for a tucking operation; and
adjusting a second fixed jaw part of a second jaw with respect to a second tucker of a delta/double parallel cylinder.
4. A folder comprising:
a collect cylinder having at least one gripper for receiving signatures, and at least one first tucker; and
a jaw cylinder having at least one first jaw for interacting with the first tucker, the at least one first jaw including a stationary jaw part and a movable jaw part, the stationary jaw part and the movable jaw part being settable independently with respect to the first tucker;
wherein the stationary jaw part is movable during a first setting operation with respect to the first tucker so as to define a first distance, and the movable jaw part is settable independently of the first setting operation so as to define a second distance between the movable jaw part and the first tucker during a tuck.
5. The folder as recited in claim 4 wherein the jaw cylinder further comprises a jaw spider, the stationary and movable jaw parts being commonly supported on the jaw spider.
6. The folder as recited in claim 4 further comprising an adjusting center or gear for moving the tucker with respect to the stationary jaw parts.
7. The folder as recited in claim 6 further comprising a cam rotatable for setting the movable jaw part with respect to the first tucker.
8. The folder as recited in claim 4 further comprising a cam rotatable for setting the movable jaw part with respect to the first tucker.
