Abstract
In order to provide a variable cutoff printing press, the press includes a pair of plate cylinders and a pair of blanket cylinders with all of the cylinders having a cylindrical body and a central axis of rotation. The plate cylinders are each mounted perpendicular to at least one side frame in a fixed position such that the axes of the plate cylinders are maintained in spaced parallel relation. The blanket cylinders are also each mounted perpendicular to the side frame by a pair of linear slide assemblies such that the axes of the blanket cylinders are maintained in spaced parallel relation. The linear slide assemblies accommodate linear adjustable positioning of the blanket cylinders along spaced parallel adjustment axes generally in the plane of the side frame. With this arrangement, the blanket cylinders are linearly adjustably positionable along and perpendicular to the adjustment axes to adjust the spacing between the plate and blanket cylinders to accommodate blanket sleeves of different thicknesses.
