Abstract
The present invention is directed to a diverter mechanism for use in a web fed rotary printing press, that is simple, low in mass, provides positive control of signatures passing through it, and can be located close to elements or mechanisms within the printing press for receiving signatures that have passed through the diverter mechanism. The diverter mechanism includes a nip formed using two cylinders. The nip can be rotated around an axis formed by the center of the nip, or can be rotated around a rotational axis of one of the two cylinders, to selectively aim a signature exiting from the nip at one of two or more receiving devices.
Claims18
A web-fed printing press including a diverting device in combination with multiple receiving devices wherein the diverting device comprises:
- first and second cylinders forming a nip between the first and second cylinders;
- at least a first belt passing through the nip and wrapping at least a portion of the first cylinder;
- and
- at least a second belt passing through the nip and wrapping at least a portion of the second cylinder, wherein
- the first and second belts convey signatures to the nip;
- and
- a mechanism for changing a transport direction of said nip by rotating the nip about a rotational axis that is parallel to the rotational axes of the first and second cylinders.

- first and second cylinders;
- at least a first belt wrapping at least a portion of the first cylinder;
- and
- at least a second belt wrapping at least a portion of the second cylinder, wherein
- the first and second cylinders press the first and second belts towards each other to form a nip between the first and second belts, and
- the first and second belts convey signatures to the nip;
- and
- the diverting device further comprises a mechanism for changing a transport direction of said nip by rotating the nip about a rotational axis that is parallel to the rotational axes of the first and second cylinders.
