Abstract

To form a web of papermaking fibers in the process of papermaking, a suspension of such fibers is passed from a head box between a pair of endless fabrics, at least one of which is a foraminous forming carrier. The fabrics are moved over paths formed by head box walls which have respective facing surfaces which are substantially impervious and which are substantially parallel over a substantial distance to and including the outlet orifice of the head box and are spaced a predetermined distance apart. Prior to any substantial formation of a web, the suspension leaves the orifice entrained between the fabrics and moves at the same speed and in the same direction. Thereafter a web of the papermaking fibers is formed by removing water from the suspension through the forming carrier without exerting substantial shear forces upon the forming web.
