Latest Patents

Lasschuit’s listed patent, “Movable deckle within headbox outlet,” describes an apparatus for forming one or more sheets from a dilute fiber suspension. The system uses a Fourdrinier wire and a headbox that delivers the suspension onto the wire, where liquid drains through a foraminous support and fibers form a mat.

The invention uses multiple liquid-impervious deckles positioned in or near the support. Each deckle extends along the headbox outlet but occupies only a small portion of its width. Feed screws or similar mechanisms move the deckles sideways and secure them in selected positions. By changing their placement, the apparatus can form one mat or several parallel mats. Lasschuit is credited with 1 patent.

Career Highlights

The available information associates Lasschuit’s work with J. M. Voith GmbH and identifies his patent as an engineering contribution to fiber-sheet formation. The adjustable deckles provide a way to control the width and arrangement of mats formed on the wire.
