Abstract
An improved, multiple-station convertible web-fed printing press is provided wherein respective press stations include permanent modules with replaceable, differently configured inserts. The station modules each include a pair of eccentrically mounted, insert-engaging rails which are pivoted for accurate placement of a press insert within the module; final insert lockup is provided by an eccentric hook assembly which generates several thousand pounds of locking force, in order to secure the insert against misalignment and subsequent insert shifting. Insert replacement operations are facilitated by means of a mobile cart including insert-supporting rails alignable with the module rails. Temporary interconnection of the cart and module rails is afforded by means of endmost connection hooks and yokes on the cart rails, which mate the module sidewall and the corresponding reduced diameter segments provided in the module rails.
