초록 ▼

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.

A method of orienting wood strands into parallelism on a moving support to form a mat thereon comprising: providing a group of elongated, generally parallel spaces above the support with each pair of adjacent spaces having a movable boundary therebetween and extending to a predetermined depth and with each boundary having a plurality of spaced projections on the upper margin thereof; directing a mass of loose wood strands toward said group of spaces from above the same so that the strands aligned with the longitudinal axes of the spaces will gravitate therethrough and onto said support; moving each pair of adjacent boundaries in opposite directions relative to each other along respective, generally straight paths to cause corresponding projections to engage those strands which span the distance between the boundaries and to turn such strands into alignment with respective spaces, the speed of movement of the boundaries relative to speed of movement of the support being sufficient to cause upended strands having first ends engaging the strand mat therebelow and second ends engaging adjacent boundaries to be turned into substantial alignment with the longitudinal axes of respective spaces before the movement of the support can cause disorientation of the strands.
