Abstract

A sheet-supporting mechanism for supporting sheets above a side guide recess in the feed table of a sheet-fed rotary printing press includes a plurality of guide bridges disposed in the recess parallel to the direction of sheet travel and slidably mounted on tie-bars in the recess for movement transverse to the direction of sheet travel. A plurality of compression springs are interposed between the lateral faces of the guide bridges to bias the bridges apart and permit the sheet side guide to move in the recess transverse to the direction of sheet travel in order to accommodate sheet formats of varying widths. The springs are preferably leaf springs and are disposed below the upper surface of the bridges which lie in the plane of the surface of the feed table.
