Abstract
A method for forming a multilayer jet by delivering a plurality of superposed, spaced apart jets of stock through a slice opening towards a web forming zone, keeping the jets separated for part of the distance between the slice opening and the forming zone, and thereafter, but not later than the arrival of the jets at the forming zone, allowing the jets to come into direct contact to produce a stratified jet. Separation of the jets in this fashion is effected by forming and maintaining gaseous wedges in the spaces between them after delivery through the slice opening.
