摘要： Wood strands are oriented into parallelism with the aid of a number of adjacent, generally parallel spaces defined by relatively thin, elongated guide members having flat sides with the longitudinal axes of the guide members extending substantially parallel to a support surface below the spaces for receiving the parallel, oriented wood strands. Each pair of adjacent guide members are moved in opposite directions to turn strands which span the guide members until the strand falls into the space therebetween. In one form of the invention, certain of the guide members have yielding projections on their upper margins and the other guide members have positive projections on their upper margins, each yielding projection having a pair of inclined end edges and each positive projection having end edges generally perpendicular to the longitudinal axis of the corresponding guide member. In another form of the invention, each guide member has spaced, yielding and positive projections with a positive projection being between each pair of adjacent yielding projections, respectively. In both forms of the invention, the yielding projections serve to raise wood strands which span the distance between three or more guide members; whereas, the positive projections operate to turn the strands until they fall between the guide members.

摘要： The invention pertains to a method of making a wood floor covering which is flexible and can be laid on concrete with a mastic using momentary pressure. Instead of the nominal 3/4-inch thickness of conventional strip hardwood floors, the floor covering is only about 1/10-inch thick. The finish on the floor covering is sufficiently wear-resistant so that for the life of the flooring the wood is never subject to wear. The finish is applied in the factory as a thermoplastic resin film which extends over the wood and spans the joints between the wood blocks of which the flooring is composed. In bonding the film a cushion is placed on the film, and heat is applied to the assembly sufficiently high to soften or melt the film. The blocks are kept from spreading apart by a constraining means partly embedded in the back of the wood by pressure, and the resin is chilled under pressure until it reaches room temperature and is solidified. In a preferred form of the flooring, the finish is the sole means for tying the blocks together, and the wood surface is rough.
摘要翻译：本发明涉及一种制造木地板覆盖物的方法，所述木地板覆盖物是柔性的并且可以使用瞬时压力施加在胶泥上的混凝土上。而不是常规带状硬木地板的标称3/4英寸厚度，地板覆盖层只有约1/10英寸厚。地板上的表面涂层具有足够的耐磨性，因此对于地板的使用寿命来说，木材绝对不会磨损。该工艺作为一种热塑性树脂薄膜在工厂中应用，该薄膜延伸到木材上并跨越地板组成的木块之间的接缝。在粘合膜时，将缓冲垫放置在膜上，并且将热量施加到组件足够高以使膜软化或熔化。通过压力将部分地嵌入木材背面的约束装置保持块不会分开，并且树脂在压力下冷却直到达到室温并固化。在地板的优选形式中，表面处理是将块结合在一起的唯一手段，并且木材表面是粗糙的。

摘要： A method and apparatus is described for use in producing a wood product comprising at least one layer of binder-coated wood strands oriented into parallelism by causing the strands to fall through elongated, parallel spaces defined by a plurality of generally rigid plates or flexible belt stretches located in vertical planes and parallel to each other above a moving support. The distance from each plate or belt stretch to the next adjacent plate or belt stretch is less than the average length of the strands. In one embodiment, adjacent, generally rigid plates reciprocate in opposite directions relative to each other. In another embodiment, adjacent belt stretches of an endless, flexible belt move in opposite directions with respect to each other. The upper edges of the plates and belt stretches have a number of spaced projections which operate to turn the strands which span two or more plates or belt stretches until the strands are aligned with the spaces therebetween and fall into such spaces toward and onto the moving support.
