Abstract
A web scoring and/or perforating apparatus for signature folding machines or the like including first and second rollers. Each roller has a scoring or perforating blade portion and a resilient roller portion. The rollers are mounted, preferably, on existing, rotatably driven nip roller shafts, upstream of web folding stages in web handling systems. The blade portion of one roller is arranged to interact with the resilient portion of the other roller. Arc lengths of the scoring or perforating roller blade portions and the resilient roller portions are substantially equal to each other and to the fold line of a signature. The rollers, between which the web is advanced, are positioned and oriented to score or perforate portions of the web in alternating directions which correspond to the direction of folding of each layer of the web.
