摘要： A method of making a belt-creped absorbent cellulosic sheet. A paper making furnish is compactively dewatered to form a dewatered web having an apparently random distribution of papermaking fiber orientation. The dewatered web is applied to a translating transfer surface that is moving at a transfer surface speed. The web is belt-creped from the transfer surface at a consistency of from about 30% to about 60% utilizing a generally planar polymeric creping belt having a plurality of perforations, under pressure, in a belt creping nip defined between the transfer surface and the creping belt. The belt travels at a belt speed that is slower than the speed of the transfer surface. The web is creped from the transfer surface and redistributed on the creping belt to form a web having a plurality of interconnected regions of different local basis weights. The web is then dried.

摘要： A headbox having a tube bank composed of a multiplicity of tubes arranged in machine direction rows of superpositioned tubes. The tubes extend from an unitary outlet wall of the headbox and are supplied by a single header or manifold. The tubes extend to the inlet of a single nozzle which is formed with an upper planar wall which converges toward a lower planar wall. The converging walls of the nozzle define two radially extending planes which converge at an imaginary centerline which extends in the cross-machine direction. The individual rows of tubes each lie along a radial plane which extends through the centerline. The radial planes defined by each tube row will preferably be evenly spaced in angle between the nozzle walls. The injection ends of the tubes lie on a defined cylindrical surface extending between the nozzle walls and extending the width of the headbox in the cross machine direction.

摘要： An absorbent cellulosic sheet is formed by belt creping a nascent web at a consistency of 30% to 60% utilizing a generally planar perforated polymeric creping belt to form a sheet with fiber-enriched higher basis weight hollow domed regions on one side of the sheet joined by a network of lower local basis weight connecting regions forming a network where upwardly and inwardly inflected consolidated fibrous regions exhibiting CD fiber orientation bias form transition areas between the connecting regions and the domed regions. When formed into roll products, the cellulosic sheets exhibit a surprising combination of bulk, roll firmness, absorbency and softness. The consolidated fibrous regions are preferably saddle shaped and exhibit a matted structure on both their outer and inner surfaces.

摘要： A headbox has a tube bank of tubes arranged in machine direction rows. The tubes extend from an outlet wall of a header to the inlet of a nozzle. The upper and lower walls of the nozzle converge toward the nozzle outlet, and planes extending from the walls (nozzle roof and apron) converge to define an imaginary centerline extending in the cross-machine direction. The rows of tubes lie along radially extending planes defined with respect to the centerline. The injection ends of the tubes define a cylindrical surface extending between the nozzle walls. Stock from each tube is directed radially toward the centerline along flow paths of equal length. Trailing vanes may be positioned between the rows of tubes so that each flow experiences almost identical flow boundary conditions as it moves towards the nozzle outlet, hence contributing to more uniform fiber orientation in the resultant paper web.
摘要翻译：流浆箱具有在机器方向排布置的管组管。管从集管的出口壁延伸到喷嘴的入口。喷嘴的上壁和下壁朝向喷嘴出口会聚，从墙壁（喷嘴屋顶和围裙）延伸的平面会聚，以限定沿横向延伸的虚拟中心线。管排位于相对于中心线限定的径向延伸的平面上。管的注射端限定了在喷嘴壁之间延伸的圆柱形表面。来自每个管的储存器沿着相等长度的流动路径径向地朝向中心线。拖尾叶片可以定位在管排之间，使得每个流体在朝向喷嘴出口移动时经历几乎相同的流动边界条件，从而有助于在所得纸幅中更均匀的纤维取向。
