Abstract
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.

A method of dewatering a forming fabric in a paper making machine, the method comprising:
- moving a forming fabric carrying a slurry stock through a dewatering area of the paper making machine;
- positioning a foil apparatus relative to a frame for supporting the forming fabric, the foil apparatus comprising an elongated foil member defining a work surface postionable relative to the forming fabric, and an elongated pulse generator coupled to the foil member along a length of the foil member, the pulse generator being mounted adjacent the work surface;
- and
- forming a nip between the work surface and the thrilling fabric by positioning the puke generator relative to the work surface, the nip for creating movement in a slurry stock of the paper making machine for reducing flocculation.
