DEWATERING BOX COVER
A dewatering box cover including a main body having a leading edge, a trailing edge opposite the leading edge, a first side edge, a second side edge opposite the first side edge, a top surface, and a bottom surface and a plurality of sets of holes formed within the main body. The holes within each set are aligned with one another along an imaginary line that is angled from 30° to 70° relative to horizontal and the holes extend downwards from the top surface of the main body towards the bottom surface of the main body at an angle of 20° to 45° relative to vertical.
DEWATERING BOX COVER
A dewatering box cover including a main body having a leading edge, a trailing edge opposite the leading edge, a first edge, a second side edge opposite the first side edge, a top surface, and a bottom surface. A first slot is formed within the main body having a first portion and a second portion angled relative to the first portion so as to form a V-shape. A plurality of second slots are formed within the main body at both sides of the first slot. The second slots and the first and second portions of the first slot extend from the top surface to the bottom surface of the main body at an angle relative to horizontal of 30° to 70° and at an angle relative to vertical of 20° to 45°.

ENDLESS WOVEN DRYER FABRIC FOR PAPERMAKING MACHINE
An endless-woven dryer fabric for a papermaking machine includes: a plurality of upper warp yarns; a plurality of lower warp yarns; and a plurality of weft yarns interwoven with the plurality of upper and lower warp yarns in a series of repeat units. Each weft yarn includes upper and lower portions, the upper portions interwoven with the upper warp yarns, and the lower portions interwoven with the lower warp yarns. The upper portion of each weft yarn includes a first seam loop and the lower portion of each weft yarn includes a second seam loop. The first and second seam loops of the weft yarns are interdigitated to form a seam, the seam receiving a pintle so that the fabric forms an endless loop.

EDGE PROTECTOR FOR A PAPERMACHINE CLOTHING
A method for producing an edge protector on a clothing for a machine producing or finishing a fibrous, paper, cardboard or tissue web, includes providing a clothing formed substantially from a woven fabric with crossing weft and warp threads and opposite side edges, applying a film strip onto a surface of one side edge and, immediately before bringing the film strip into contact with the clothing, surfaces of the film strip and the clothing facing each other are heated to slightly melt the surfaces. A pressing force exerted on the film strip applied to the surface of one of the side edges, results in the film strip penetrating at least partially into the woven fabric. That side edge of the clothing with the film strip is cooled, resulting in a stable, particularly integrally joined and form-locking connection between the film strip and the side edge of the clothing.

Methods of making fabric-creped absorbent cellulosic sheets
A method of making a fabric-creped absorbent cellulosic sheet. The method includes compactively dewatering a papermaking furnish to form a web having a consistency of about thirty percent to about sixty percent, creping the web under pressure in a creping nip between a transfer surface and a structuring fabric, and drying the web to form the absorbent cellulosic sheet. The absorbent sheet has SAT capacities of at least about 9.5 g/g and at least about 500 g/m.sup.2. A creping ratio is defined by the speed of the transfer surface relative to the speed of the structuring fabric, and the creping ratio is less than about 25%.

A method of making a fabric-creped absorbent cellulosic sheet. The method includes compactively dewatering a papermaking furnish to form a web having a consistency of about 30 percent to about 60 percent, creping the web under pressure in a creping nip between a transfer surface and a structuring fabric, the structuring fabric including knuckles formed on warp yarns of the structuring fabric, with the knuckles having a length in the machine direction (MD) of the absorbent sheet and a width in the cross machine direction (CD) of the absorbent sheet, wherein a planar volumetric density index of the structuring fabric multiplied by a ratio of the length of the knuckles to the width of the knuckles is at least about 43, and drying the web to form the absorbent cellulosic sheet.
