Abstract: Lumber sorting systems and methods that use adaptive lumber management to tailor the distribution of lumber to improve the yield and aesthetic properties of a product are disclosed. An adaptive lumber management system in accordance with the present disclosure may comprise a lumber scanner configured to record one or more characteristics of each board and create a data file for each board comprising information regarding the characteristic of the board. A processor may be configured to determine a target tray for each board based on the data files. The processor may be further configured to generate at least one mapping. The system may further comprise a sorting mechanism configured to sort the plurality of boards into their respective target trays and at least one tipple configured to select each board or the plurality of boards from the plurality of trays according to the at least one mapping.

Abstract: A door has a core that includes a porous layer having a thickness and two opposing major surfaces. In one construction, the core also includes three fire-retardant layers, and two of the fire-retardant layers are separated by the porous layer. The porous layer and the fire-retardant layers are coupled together. Other constructions include one or more fire-retardant layers in balanced or unbalanced placement around the porous layer.

Abstract: Disclosed are automated processes and systems for the assembly of composite doors, and doors made using such processes and systems. The automated process may comprise a continuous series of steps allowing individual doors to be made in tandem, rather than in batch. The process may allow for the automation of individual steps such that the need for coordinating separate assembly steps may be substantially reduced.
