20080220110 | Gypsum Board Forming Device with Improved Slurry Spread - Disclosed is a gypsum board forming device which provides improved slurry spread. The device includes a forming table with an arcuate or angled profile that promotes a uniform slurry spread. An arcuate or angled hinge plate can also be included to further promote the uniform distribution of slurry prior to an extrusion plate. As a result of the improved slurry spread, gypsum board with increased strength and durability can be created | 09-11-2008 |
20090025880 | APPARATUS FOR TARGETED DELIVERY OF ADDITIVES TO VARYING LAYERS IN GYPSUM PANELS - A multilayer gypsum board forming device, and a gypsum additive delivery system in which additives are delivered to one or more layers of a multi layered gypsum board panels, including engineered polymers, includes at least one additive assembly connected in-line with a first gypsum delivery receptacle for providing an additive fluid feed into the stream of a first gypsum slurry being transported through said first gypsum delivery receptacle for homogenously adding an additive to the first gypsum slurry, and a second gypsum delivery receptacle transporting a second gypsum slurry, in fluid communication with the mixer providing the first gypsum slurry, having a different set of characteristics from those of the first gypsum slurry. At least one outer surface including a polymeric compound or wax emulsion additive entrained therein essentially encases the core gypsum within two facing layers. | 01-29-2009 |
20090087616 | COATINGS FOR GLASS REINFORCED FACED GYPSUM BOARD - A coating method for gypsum board having a surface gypsum layer in which a polymer additive has been entrained including forming a gypsum board including the polymer additive entrained in a surface layer, application of a preferably acrylic primary coating, curing and drying the gypsum board, passing the gypsum board through a first roll coater wherein a second fluid coating is deposited over the primary layer of the dried, coated gypsum board in which the polymer additive has been entrained, the coating then being dried and cured, wherein the coating material of the primary coating forms a chemical bond with the polymer additive entrained in the surface layer of the gypsum board and the polymer of the primary coating forms a chemical bond with the second fluid coating. A coating material which can form copolymer bonds with the second coating is then deposited on the second coating and then dried and cured, resulting in coated gypsum board having a low surface tension surface that is essentially impermeable to water and vapor or moisture penetration. | 04-02-2009 |
20090297865 | GLASS REINFORCED GYPSUM BOARD AND METHOD OF MANUFACTURE - A gypsum-containing panel and a method of making it are disclosed including at least one facing layer having a first polymer that is reinforced with reinforcing fibers and a gypsum core that has a second polymer in a second polymer matrix interwoven with a gypsum matrix. The first polymer in the facing layer and said second polymer matrix in said gypsum core form a continuous polymer matrix, and can be the same polymer material. | 12-03-2009 |
20100132519 | Fastening System for Sheathing Board - Disclosed is a fastening system that is adapted for securing a sheathing board to an associated framing member. The system includes a feedband for retaining a series of fasteners and a powered drill for sequentially driving the fasteners. The feedband is made from a membrane of a polymeric compound. As the fastener is driven into the sheathing board, a portion of the membrane tears away from the surrounding feedband and becomes seated beneath the fastener. This acts to seal the penetration point and prevent water intrusion and otherwise prevents deterioration of the sheathing board. | 06-03-2010 |

The device includes a forming table with an arcuate or angled profile that promotes a uniform slurry spread. An arcuate or angled hinge plate can also be included to further promote the uniform distribution of slurry prior to an extrusion plate. | 08-16-2012 |
