Abstract: A system is disclosed for attaching in a needling apparatus, such as a needle loom, tacker and the like, a plurality of needle boards to a plurality of needle beams in alignment therewith. A plurality of needle boards having upwardly extending attachment members are supported on a plurality of needle board carts which are movable into the needling apparatus to a position underling one of the needle beams for attachment thereto. The carts are supported by the stripper plate as they move through the needle zone. Each of the carts includes a locator member for alignment of the needle board therewith when supported on the cart. The carts and support needle boards are raised for engagement with the needle beam by operation of the stripper plate. The needle beams include a support plate having a plurality of openings for receiving therethrough the attachment members of a corresponding needle board, thereby aligning the needle board at a predetermined position to the needle beam.

Abstract: A printing press comprises a frame. A plate cylinder is mounted in the frame for rotation about a first axis and a blanket cylinder is mounted in the frame for rotation about a second axis. The plate cylinder and the blanket cylinder have a contact pressure therebetween for printing operation. A skew eccentric is supported by the frame and is associated with at least one end of the plate cylinder. The skew eccentric is operable to change the relative angular positions of said first and second axes. A means is connected with said skew eccentric for maintaining the contact pressure between the plate cylinder and the blanket cylinder substantially unchanged upon rotation of the skew eccentric.
