  • Patent number: 8091952
    Abstract: A hardwood floor used for making trailers in the transportation industry is treated, at least for a portion thereof, with a water-based wood preservative. The preservative is preferably a borate-based preservative. When the floor is provided with a steel plate at a rear thereof, the wood preservative located in the vicinity of the steel plate prevents the formation of fungi and increases the useful life of the floor.

  • Patent number: 7926524
    Abstract: In a wood processing plant, planks are typically split into strips and then passed through an automated cross-cutting saw station to remove defects such as knots, cracks or flash. One defect which also occurs is the hit and miss defect caused by a planer and/or a sander. In order to improve the performance of the cross-cutting saw station, color is applied to the wood prior to being planed and sanded. The cross-cutting saw station is then modified to optically inspect the wood for the presence of color, indicating a hit and miss defect, and to remove the portions of the wood containing color.

  • Patent number: 6957675
    Abstract: An apparatus and method for simultaneously pressing together longitudinally a plurality of individual strips of wood, each strip being provided with a finger joint at each end. The strips are jointed end to end in a number of rows to form a floorboard. The apparatus includes a mechanism for simultaneously applying longitudinal pressure to each of the rows of wood strips during the curing process. The resulting floorboard is mechanically improved, has greater protection against humidity and increases the fatigue resistance of the floorboard, which can be used for trailer floors or the like.
