Abstract
A burster mechanism for separating continuous form webs into sheets along transverse pre-weakened lines comprising two sets of feeding means spaced along a curved web path so that one set of rolls is at an angle to the other. A curved guide member which extends between the two feeding means defines the outer curvature of the web path. The second feeding means is operable at a faster rate than the first feeding means and is actuated at a predetermined time to draw the web taut between the feeding means and separate the sheet from the web.
