Abstract: Residues from fibermat materials are broken down and separated into wood fibers and other fibers so that the fibers may be recycled. If the fibermat residues are not recycled, they present a disposal problem due to the uncured resins that become toxic waste. The fibermat residues are cut and separated by rotating cutting heads within a cutting and separating chamber. The wood fibers, being the heavier fibers, settle out, pass through a screen into a collection chamber and the lighter textile fibers are sucked out of the cutting and separating chamber with a vacuum system.

Abstract: A panel is disclosed that is formed from a planar, substantially inflexible cellulosic substrate having a rough or uneven surface, at least one layer of paper or veneer and a layer of an electrically conductive wire mesh or metal foil interposed between the substrate and the layer of paper or veneer. The substrate and the layers are bonded together with a layer of a polyolefin that has been grafted with an ethylenically unsaturated carboxylic acid or anhydride. The polyolefin is a homopolymer of ethylene or copolymer of ethylene and a higher hydrocarbon alpha-olefin. Processes for the manufacture of the panel are also disclosed. The panel may be used in the construction industry, especially as electrical shielding or for the removal of stray electrical currents from electrical or other equipment.
