Abstract

A method and mechanism for forming multi-ply continuous fibrous web by providing a twin wire former including first and second looped forming wires positioned to provide a dewatering run therebetween with a tapered throat at the upstream end of the run and supporting rolls within each of the wires including suction breast rolls having a plurality of suction glands within the rolls for the graduated application of suction to the wires and an intermediate headbox delivering a jet of stock slurry into the throat with outer headbox delivery outer jets for the outer layers of the web and the intermediate jet being delivered after the dry line of the outer layers. Air inflatable bellows are connected between the inner slice lips of the outer headboxes and the slice walls of the intermediate headbox to control the thicknesses of the outer plys.
