    摘要： An automated inline rip saw system utilizing x-ray and optical scanning techniques to identify and detect flaws within a piece of wood. The present system may further utilize a precision skewing unit which may reduce or eliminate errors while allowing for precision rip cuts to be performed. Further, the present automated inline rip saw system may utilize multiple independently controlled saw blades to perform precision cuts. Finally, the present inline rip saw system may allow for more accurate detection of flaws or undesirable inclusions within the wood earlier in the wood production process, including the ability to scan for, identify, and remove sap wood from green lumber.

    摘要： A process for producing a smooth-sided strand-based siding or wood structural panel using a secondary pressing process. The secondary pressing process is performed after the primary process completes pressing and consolidation of the substrate/board. The secondary process applies and cures the overlay after applying a water spray on the hot board immediately out of the primary process press, and before overlay application. The application of the water spray causes the surface of the board to swell and cure. A settling period follows to allow the top surface particles and strands to swell along with absorption and evaporation of the moisture. This is followed by surface sanding to remove the telegraphing and produce a smooth surface, which is then followed by lamination of the overlay(s). The process is completed by post-lamination treatment and coating of the board.

    摘要： A saw tooth includes a body, a plurality of petals, and a plurality of inserts. The body has a forward surface defining a perimeter, a rearward surface, and, a plurality of sides extending between the forward and rearward surfaces. Each petal has a forward surface and a rearward surface, and the rearward surface defines a perimeter. The petal is coupled to the forward surface of the body. The perimeter of the rearward surface of the petal does not extend outwardly beyond the perimeter of the forward surface of the body. Each insert is positioned between two of the petals, is coupled to the body, and has an outer side. The outer side of the insert extends outwardly beyond a corresponding side of the body.
