    • 专利摘要:
    The discharge pipes of a plurality of stock pumps, each supplying a separate concentrated stock slurry, are connected with a pipe containing comparatively dilute stock, commonly called "white water", discharged under pressure from a single fan pump on a single white water silo to supply separate slurries to separate chambers of a multi-ply web forming machine. The stock pumps have smaller capacities and pressure heads compared with a fan pump, thereby providing increased efficiency at required capacity with the minimum of equipment.

    Lot II, the process of producing a multi-layer web is greatly simplified.
    Form m u l a and 3 o b e e e u u
    Method for the production of multilayer canvases by feeding a fiber suspension from separate containers through the knotters to a section of the headbox, followed by a net ebb and collection of recycled water, t:; and h and y y. and in order to simplify the production process of the web, the circulating water is collected in a common container, from where it is fed to each knotter to form the concentration of fibrous suspension required for each layer of the web.
