Abstract
A dehydration element for the fourdrinier part of a paper making machine is a metal or plastic twill-weave binding fabric in which the longitudinal (warp) threads bound to the woof threads are closely spaced to each other up to the point where the longitudinal threads are tightly pressed together. The result is a substantially closed mesh in which water drawn from the pulp passes through the element by capillary action in the fine channels and diagonal openings of the cloth. Preferably the cloth is an unevenly bound twill-weave with its paper side unifilarly bound and its machine side multifilarly bound.
Claims5
A dehydration element for the fourdrinier part of paper making machines has a paper side and a machine side and comprises longitudinal threads bound to woof threads with said longitudinal threads being closely spaced together so that adjacent ones of said longitudinal threads contact each other to provide a closed mesh fabric with fine channels therethrough defined by said longitudinal and woof threads, said fabric being an unevenly bound twill-weave with the paper side of the fabric being unifilarly bound.
