Abstract

The present invention provides a fabric for a papermaking machine. The fabric includes a machine facing side and a web facing side having pockets formed by warp and weft yarns. Each pocket is defined by four sides on the web facing side, three of the four sides each being formed by a knuckle of a single yarn, and one of the sides being formed by a knuckle of a weft and of a warp yarn, wherein theweft yarn also defines a bottom surface of the pocket.

Description

technical field [0001] This invention relates generally to papermaking, and more particularly to structured forming fabrics for papermaking. The invention also relates to a structured forming fabric having deep pockets. Background technique [0002] In the conventional fourdrinier papermaking process, an aqueous suspension or suspension of cellulosic fibers (commonly referred to as paper "stock") is fed to an endless belt of woven wire and / or synthetic material running between two or more rolls. On the upper run. The belt, often referred to as a "forming fabric", forms the papermaking surface on its upper surface of the overflow, which acts as a filter for separating the cellulose fibers in the pulp stock from the aqueous medium to form wet paper Web (paper web). The aqueous medium is drained through the mesh of the forming fabric, commonly referred to as the weep holes, by gravity or a vacuum located on the bottom surface of the overflow on the fabric (ie, the "machine s...
