Abstract: A method for reducing or eliminating forming fabric edge curl includes slitting or scoring the knuckles formed by cross-machine direction yarns (14) on the long-shute knuckle side (16) of a papermaker's forming fabric (10). The knuckles are scored or slit to a depth no greater than half the diameter of the cross-machine direction yarns. At least one such slit or score (18) is provided per knuckle (20). The scoring or slitting has the effect of bringing the ratio between the shrink forces acting on the two sides of the forming fabric in the cross-machine direction closer to unity, and, in turn, reduces or eliminates the edge curl resulting from shrinkage in the cross-machine direction.

Abstract: A dewatering system is disclosed in papermaking machine for removing water from a web (P) such as a paper sheet made of pulp. The drainage system includes a vacuum or suction box (1), a separator (3) for separating solids and/or liquids from the drainage, and vortex valve (6) connecting the separator (3) to vacuum (5). Advantageously, the vortex valve (6) operates to maintain a substantially constant pressure at the separator outlet independently of the gas flow through the valve (6).

Abstract: A papermaker's fabric (10) having a smooth surface and a prolonged life includes flat machine-direction yarns (26, 28) which define the upper and lower surfaces thereof. The fabric has two layers of cross-machine direction yarns (18, 18', 22, 22'), each of which is interwoven with the flat machine direction yarns (26, 28). Other machine direction yarns (24), of round cross section, weave with the cross-machine direction yarns (18', 22') in the two layers to bind them together. At one of the two ends of the fabric, seaming loops (30) are formed by the round machine-direction yarns. At the other of the two ends, seaming loops (34) are formed by the flat machine-direction yarns (26, 28). The seaming loops (30, 34) are interdigitated with one another, when the two ends of the fabric (10) are brought together during installation on the paper machine, defining a passage through which a seaming pin or pintle (42, 50, 58) is directed to join the two ends (30, 34) together.

Abstract: A laminated integrally woven on-machine papermaker's fabric (10) includes two single-layer woven fabric plies sharing a common machine-direction (MD) yarn (20, 20'). The common MD yarn, which is the weft yarn on the loom during a modified endless weaving technique, forms seaming loops (18) which join the plies together at their ends. Solvent-removable binder yarns (22) interconnect the two plies, which are integrally woven. After weaving, the binder yarns are removed through dissolution with a solvent, yielding the laminated structure. A batt of staple fiber material (36) may be needed into and through the laminated structure. The papermaker's fabric may be used as a forming, press or dryer fabric, or as a base for a polymer coated, paper industry process belt, such as a long nip press, sheet-transfer or calender belt.

Abstract: A method for manufacturing a resin-impregnated endless belt structure is carried out on an apparatus (60) having an outer cylinder (66) and an inner cylindrical surface that is coaxial with a smaller radius cylindrical mandrel (64). An endless base structure is disposed with the outer cylinder (66) on the inner cylindrical surface. The cylindrical mandrel, having an inwardly curved nose (68), is then inserted into the outer cylinder (66) forming a nip (70) between the curved nose (68) and the inner cylindrical surface. Polymeric resin is dispensed continuously into the nip (70) while the cylindrical mandrel is gradually moved into the outer cylinder (66). The nose forces the resin into the endless base structure and expels air bubbles while forcing the endless base structure against the inner cylindrical surface. After the polymeric resin is cured, the endless belt structure, having a totally impregnated, air-bubble free endless base structure with a coating on its inner surface, may be obtained upon removal of the apparatus (60).
