Abstract

An apparatus for marking a longitudinal edge of a travelling web has a marking (e.g. notching) station, upstream but adjacent to which is located an abutment. Upstream of the abutment is located aguide arrangement which urges the web transversely of the direction of web travel at an angle skew to the longitudinal centerline of the web, so as to exert on the web a force acting skew to the centerline in the forward direction of web travel and towards the edge to be marked. This urges the edge in part against the abutment to assure that the web travels in predetermined orientation through the marking station.
