Foil apparatus for paper making machine

Abstract

A foil apparatus for a paper making machine includes a foil member positionable relative to forming fabric of a paper making machine, and a pulse generator coupled to the foil member, the pulse generator being adjacent to the foil member for forming a nip between the foil member and the forming fabric, the nip for creating movement in a slurry stock for reducing flocculation. A method of dewatering a forming fabric in a paper making machine includes moving a forming fabric carrying a slurry stock through a dewatering area of the paper making machine; positioning a foil apparatus for supporting the forming fabric, the foil apparatus having a foil member defining a work surface and a pulse generator coupled to the foil member adjacent the work surface; and forming a nip between the work surface and the forming fabric by positioning the pulse generator relative to the work surface.
