Folder with signature removal and slowdown process
View Patent ↗A folder includes a cylinder having a first gripping device receiving a folded edge of a signature and rotating the signature at a first surface speed. A conveyor presses the signature against the outer surface and the conveyor contacts the signatures at a second surface speed slower than the first surface speed. The present invention also provides a method for removing signatures from a cylinder.
1. A folder comprising:
a cylinder having a first gripping device receiving a folded edge of a signature and rotating the signature at a first surface speed; and
a conveyor pressing the signature against an outer surface of the cylinder while the conveyor contacts the signature at a second surface speed lower than the first surface speed.
2. The folder as recited in claim 1 wherein the conveyor is a belt.
3. The folder as recited in claim 1 wherein the second surface speed is less than the first surface speed.
4. The folder as recited in claim 1 wherein the second surface speed is between 75% and 95% of the first surface speed.
5. The folder as recited in claim 1 further comprising a second conveyor receiving signatures from the conveyor.
6. The folder as recited in claim 1 wherein the cylinder is a jaw cylinder.
7. The folder as recited in claim 1 further comprising a stationary or fixed stripper located next to the cylinder.
8. The folder as recited in claim 1 further comprising a moving support located within a circumferential groove of the cylinder.
