ABSTRACT OF THE DISCLOSURE Interstacked longitudinally offset form sets from continuous webs are fed through upstream low speed rollers and downstream rollers, with a breaker bar disposed between the roller pairs. The upper roller of the slow roller pairis mounted eccentrically to engage the webs between the upper and lower rollers of the slow roller pair once for each revolution of the upper roller. When a leading portion of one web enters the nip of the downstream rollers, the eccentrically mounted upper low speed roller engages the webs and the downstream roller pairs are rotated at a higher speed to create sufficient tension in the form between the pairs of rollers such that the form engages against the breaker blade to burst the form from the web. Upon bursting, the eccentric low speed roller disengages or opens relative to the webs and the leading portion of a form of the other web engages in the nip of the downstream roller pair whereupon the bursting of the form from the second web is accomplished.
