Abstract:
Disclosed is a wood composite material comprising: wood strands disposed in surface layers and one or more core layers, whereby an intermediate density divides the wood strands so that the two surface layers of strands are more dense than the intermediate density, and the one or more core layers of the strands are less dense than the intermediate density, and wherein the core layer contains at least about 70 wt% of the strands that are less dense than the intermediate density; and the surface layers contain at least about 70 wt% of the strands that are more dense than the intermediate density.

Abstract:
A patterned pressure roller for tape applicators useful for reducing the pressure required to seat pressure-sensitive tape and methods of use thereof.
Abstract:
An I-joist is provided comprising a first and a second flange interconnected by a webstock; the first flange has a first major surface upon which is formed a groove, so that the groove faces and receives the webstock; and a fiberous re-enforcing material impregnated with adhesive resin disposed in the groove.
Abstract:
A single package, ready-to-use (RTU) resin/wax emulsion adhesive and a method of preparing the same by heating a thermosetting resin and adjusting the pH of the wax emulsion prior to combining the resin and wax emulsion. The use of the adhesive in making bonded composites such as wood products, including oriented strand board (OSB), parallel strand lumber, wafer board and particle board composites.

Abstract:
Structural members, building structures, and methods for making them, are provided that are less prone to develop squeaks. The methods include, in one aspect, placing at least one panel on the flange surfaces of joists with an activatable adhesive provided between the panel and the flange surfaces to bond the flange surfaces to the panels in an effective long lasting manner. In another aspect, adhesive is introduced into a groove array in a joist flange surface to attach a panel pre-positioned on the grooved flange surface. Building frame structures, such as subflooring assemblies, made by the methods are also provided.
