    摘要： A printing press is provided that includes at least one variable cutoff printing unit printing images of at least one cutoff length on a web, at least one cutting cylinder downstream of the at least one variable cutoff printing unit cutting the web into signatures. The printing press also includes a pair of first accelerator nip rolls receiving the web as the web is cut into the signatures and accelerating each of the signatures and at least one motor accelerating the pair of first accelerator nip rolls such that the first accelerator nip rolls have a first surface velocity equal to a velocity of the web as the web is received by the first accelerator nip rolls and the first accelerator nip rolls have a second surface velocity greater than the first surface velocity as the first accelerator nip rolls release each of the signatures. A folder and a method of operating a folder are also provided.

    摘要： A variable cutoff web cutting apparatus is provided including a first knife cylinder having a first segmented knife blade. The first knife cylinder rotates about a first cylinder axis in a web travel direction and the first segmented knife blade rotates about a first knife axis in the opposite direction. Also included is a first counterpart cylinder, which the first segmented knife blade contacts to perforate a web. The cutting apparatus also includes a second knife cylinder having a second knife blade. The second knife cylinder rotates about a second cylinder axis in the web travel direction and the second knife blade rotates about a second knife axis the opposite direction. Also included is a second counterpart cylinder, which the second knife blade contacts to cut the web adjacent to where the first segmented knife blade perforated the web, so as to sever the web and create a signature.
