Description

ABSTRACT:
A twin wire former of a paper making machine in which one of the wires is supported on a surface of each of a number of forming shoes longitudinally spaced along the extent of the wires. Each forming shoe has a number of longitudinally spaced grooves in the surface contacted by the one wire, each of the grooves extending in a direction at an angle to the longitudinal direction less than 90.degree., such that scraping pressure applied to the raw material liquid guided between the two wires, by the surface between the grooves is released into the grooves. This arrangement of grooves creates a pressure difference in the raw paper material liquid in a direction transverse to the longitudinal direction of the wires to produce a transverse flow of the raw paper material liquid, thereby reducing the machine-direction to cross-machine-direction ratio of the fibers of the paper being formed.
