Abstract: A valve for a vacuum drainage system includes a valve body having an interior chamber operatively connectable to a suction device and through an outlet to a vacuum source. A movable member having an aperture is secured within the chamber and movable through points between closed and open positions to adjust the open area of the aperture and the fluid flow through the outlet. The aperture is configured such that during adjustment to increase the effective operational area of the aperture, a rate of change of the effective operational area increases non-linearly in relation to a linear increase in the distance of travel, while providing advantageous and more controllable linear adjustment of the applied vacuum. The aperture can have a trilateral shape including at least one curved side, or comprise a plurality of sub-apertures, and the movable member can comprise a rotary sleeve.

Abstract: A forming section for a twin fabric papermaking machine, wherein after stock impingement, the two fabrics carry and sandwich the stock. A plurality of spaced apart drainage shoes, selectively provided to either or both of the fabrics, provides continuous support in the machine direction for the respective fabric in sliding contact, and each drainage shoe deflects the fabrics by a selected angle of wrap comprising an angular displacement between the leading edge and the trailing edge of the drainage shoe. At least one of the drainage shoes is secured to a drainage box and is provided with a plurality of drainage openings extending from the fabric contacting surface through to the machine side surface of the shoe. The arrangements of the invention provide improved drainage and formation of the paper web.

Abstract: A headbox including a stock dilution profiling arrangement and associated stock delivery systems are provided, which together deliver to the forming section of a papermaking machine a uniform stock flow with more consistent basis weight and fiber orientation profiles than has previously been possible. These improvements in basis weight uniformity and fiber orientation profile provide benefits in paper sheet formation and related paper properties.

Abstract: Twin wire former and method for manufacturing a fibrous material web from a fibrous suspension using same. The twin wire former comprises a movable bottom wire belt and a movable top wire belt converging at a twin wire zone. The twin wire zone has a first section, a second section and an end section. A rotating forming roller is disposed at the first section of the twin wire zone, and the to wire and the bottom wire form a wedge-shaped inlet gap at the first section of the twin wire zone. The inlet gap is adapted to receive the fibrous suspension from a headbox. The bottom wire belt and the top wire belt are adapted to form the fibrous web therebetween at the second section of the twin wire zone, and the second section of the twin wire zone has at least one drainage element. A separating device is disposed at the end of the twin wire zone and is adapted to separate one wire belt from another the wire belt.

Abstract: An abrasive article comprising: (a) a backing having a first major surface; (b) an abrasive layer coated on the first major surface, the abrasive layer comprising (i) an organic-based bond system, and (ii) a plurality of abrasive particles adhered in the bond system; and (c) an outermost coating layer comprising a poly(vinyl carbamate) polymer at least partially coated over said abrasive layer, and a method of making and using the abrasive article.
