| A clothing for supporting a wet paper web for dewatering is provided, comprising a dewatering fabric extending in a machine direction and formed only from a woven material to have a single, substantially consistent, permeability. A pair of laterally-spaced strip portions extend along the dewatering fabric in the machine direction, with each being substantially and consistently impermeable to air and forming a substantially and consistently smooth non-water-retaining surface. The strip portions define a permeable web-carrying portion of the dewatering fabric therebetween, wherein the paper web carried thereby extends over the entire width thereof. The permeable web-carrying portion allows air to flow therethrough, exclusively of the impermeable strip portions, such that the wet paper web carried only by the permeable web-carrying portion is dewatered. The width of the permeable web-carrying portion thereby defines the width of the wet paper web dried thereon. Associated systems and methods are also provided. | ||||||

| 46 | Trim hold down box apparatus | US10300701 | 2002-11-20 | US06841043B2 | 2005-01-11 | Shawn S. Devoe; Marvin D. Hoekman; Leonard A. Scharlau |
| A trim hold down box apparatus is disclosed for assisting in the separation of trim cut from an edge of a sheet by a cutter prior to the sheet being transferred from a forming wire of a forming section to a press section of a paper making machine. The apparatus includes a frame which is adjustably secured to the former and is disposed downstream relative to the cutter. A box cradle is secured to the frame and a trim box is movably connected to the box cradle such that floating of the trim box with the forming wire is permitted. The arrangement is such that the forming wire is disposed between the trim and the trim box. A biasing arrangement extends between the trim box and the box cradle so that biasing of the trim box relative to the forming wire is permitted. The trim box has a first and a second end and the first end of the trim box is connected to a source of partial vacuum. The second end of the trim box cooperates with the forming wire and is disposed in a vicinity of the trim. The arrangement is such that when the first end of the trim box is connected to the source of partial vacuum, separation of the trim from the sheet being transferred into the press section is assisted by the partial vacuum applied to the trim at the second end of the trim box. | ||||||
