| 20150330021 | Compact Former Section - A former section including a headbox, a felt, a wire, a forming roll having a suction zone and a forming section, and a gap section defined by the section between the headbox and a position where the felt and the wire are brought together at the forming roll. The headbox distributes a pulp slurry into the gap section to be sandwiched by the felt and the wire to form a paper sheet. A bottom side of the paper sheet contacts the felt and a top side of the paper sheet contacts the wire, and the sandwiched felt, paper sheet and wire wrap around the forming roll. A press roll forms a nip with the forming roll through which the paper sheet is carried by the felt and the wire, and the suction zone of the forming roll is arranged in a section around the nip. | 11-19-2015 |
| 20160069022 | SEAMED PRESS FELT INCLUDING AN ELASTIC CARRIER LAYER AND METHOD OF MAKING - A seamed press felt formed from a base fabric material including MD yarns arranged in two superimposed layers joined by the MD yarns at CD folds at opposing ends thereof to form a continuous unbroken tube-like structure. The MD yarns form loops at the folds to define a pintle channel. A generally planar yarn assembly including an array of polymeric yarns bonded to an elastic carrier material that is extensible by at least 1% is located inside the base fabric with the yarns of the array oriented in the CD. A high surface contact area material is bonded to the elastic carrier material at both exterior MD ends adjacent to the MD loops at the folds. Each of the MD ends is anchored in a fixed position adjacent to the loops at the folds. A pintle extends through the channel defined by intermeshing the loops from the opposing ends. | 03-10-2016 |
| 20160186379 | SHEET MANUFACTURING APPARATUS AND SHEET MANUFACTURING METHOD - A sheet manufacturing apparatus includes a defibrating unit that defibrates a raw material containing fiber in the atmosphere, a forming unit that forms a sheet by using at least a part of a defibrated material that is defibrated by the defibrating unit, a first supply unit that supplies a first paper material to the defibrating unit, and a second supply unit that supplies a second paper material to the defibrating unit. At least one of the first paper material and the second paper material is a paper material having a resin layer. | 06-30-2016 |
