20090283218TRIM DEVICE RESISTANT TO VARIATIONS IN ATMOSPHERIC TEMPERATURE AND HUMIDITY - A finish trim for use in dry wall construction having an elongated core that is configured with a flange having outwardly facing surfaces to which is affixed a pre shrunk covering strip.11-19-2009
20090294067PRODUCTION LINE FOR HYDRAULIC BINDER-BASED, TAPERED-EDGE BOARDS - The subject of the invention is a novel plasterboard and its manufacturing processes. The novel board comprises, on one side, two first parallel feathered edges and, on the other side, two other, second, parallel feathered edges that are perpendicular to the first ones; or, on one side, two first parallel feathered edges and, either on the same side or on the other side, two second parallel feathered edges that are perpendicular to the first ones, the said other parallel feathered edges having a width of between 100 and 200 mm; or, on one side, two first parallel feathered edges and, either on the same side or on the other side, two second parallel feathered edges that are perpendicular to the first ones, the said second parallel feathered edges having a width such that the ratio of the width of the said second parallel feathered edges to the width of the said first parallel feathered edges is between 1.5 and 5.12-03-2009
20090025880APPARATUS 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
20120205047Gypsum 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.08-16-2012
