Abstract

A method and apparatus for makeready of a web press having an unwind apparatus for supporting a rolled web of material and having a plurality of rotatable members in spaced alignment defining a path for the web and arranged to perform operations on said web such as printing, perforating, numbering, punching or slitting, wherein the members are rotated in synchronism and are adjustable laterally and/or circumferentially with respect to the web path, is disclosed as comprising markings and scales establishing a reference position in the unwind apparatus for the rolled web and establishing separate side reference positions for each of said rotatable members which has a lateral adjustment with respect to the unwind reference position, and further markings and scales establishing a circumferential reference position for each of said rotatable members with respect to each other. A coordinate layout system for preparing a makeready job sheet is also provided with marks corresponding to the reference positions and scales in dimensions corresponding to said scale devices. A job sheet having dimensional settings is prepared with the layout system, using a representation of the desired product, whereby measurements are provided for lateral and circumferential adjustment of the adjustable rotatable members using their respective scale devices and the settings for the rotatable members can be accomplished with precision to minimizie their adjustment once the web is threaded through the press and a run is started.
