摘要: A device for cutting a web of material, the web having a web velocity and moving in a web direction. The device includes a plurality of linearly movable cutting elements capable of moving in the same direction as the web direction for cutting the web into signatures, and a plurality of gripper elements interacting with the cutting elements. A method for cutting a web includes the steps of linearly moving a plurality of cutting elements within a signature formation area, the web also moving within the signature formation area, the cutting elements and the web moving in the same direction; cutting the web with the plurality of cutting elements so as to form signatures; gripping the signatures; and varying a length of the signatures by varying a spacing between cutting elements in the signature formation area.

摘要: A composite nip roll or nip ring that is durable and requires minimal adjustment, and which accurately provides a constant gain. In accordance with an exemplary embodiment, the nip roll or ring has a rigid shaft, a resilient polymer inner material mounted on the rigid shaft, and a metal outer covering over the resilient polymer inner material. The metal covering can be rigid or flexible. The nip roll can also include limiting rings that limit deflection of the outer covering to a maximum amount.

摘要: An apparatus for removably securing a cutting component on a cutting component cylinder of a web printing press includes a first axial anvil member disposed at a periphery of the cutting component cylinder and a second axial anvil member disposed at the periphery of the cutting component cylinder opposite the first anvil member. The first and second anvil members receive the cutting component between them. A locking device is provided for positively securing the cutting component on the cutting component cylinder in a lock mode and positively releasing the cutting component in a release mode.
