专利汇可以提供Apparatus for orienting wood strands专利检索，专利查询，专利分析的服务。并且An apparatus for orienting elongated wood strands in the production of particleboard. The apparatus comprises a multiple number of vertical decks, each including stationary vertical fins arranged parallel to one another. The top edge of each fin is covered by a fin cap that is vibrated with both a vertical and horizontal component of movement. Adjacent fin caps in each deck are out of phase and moved oppositely at any given moment. Each deck comprises a multiple number of fins in relation to the deck immediately above it, with correspondingly spaced fin and fin cap assemblies being in vertical alignment. Provision is also made for vertical adjustment of the fin and fin cap assemblies relative to the receiving surface on which the oriented particles are deposited.，下面是Apparatus for orienting wood strands专利的具体信息内容。
1. An apparatus for orienting wood strands or the like in parallel directions during deposition of the strands to form a mat, comprising: a supporting framework; a plurality of vertical fin assemblies spaced parallel to one another by a distance less than the length of the wood strands, said fin assemblies grouped vertically in at least two decks, with each deck having a multiple number of fin assemblies spaced thereon relative to the deck immediately above it and including fin assemblies vertically aligned with the fin assemblies of the deck immediately above it, the upper edges of the fin assemblies in each deck being coplanar and horizontal; power means on said framework operatively connected to the fin assemblies for imparting vibratory motion to the upper edges of the fin assemblies; and receiving means immediately below the lowermost deck of said fin assemblies for receiving wood strands after passage thereof between said fin assemblies.
2. An apparatus as set out in claim 1 wherein each fin assembly includes an upright elongated fin cap slidably mounted to the upper edge of a fin fixed to the framework, said power means being connected to said fin caps.
3. An apparatus as set out in claim 1 wherein each fin assembly includes an upright elongated fin cap slidably mounted to the upper edge of a fin fixed to the framework, said power means being connected to said fin caps, the vibratory motion imparted to the fin caps having both vertical and horizontal components.
4. An apparatus as set out in claim 1 wherein each fin assembly includes an upright elongated fin cap slidably mounted to the upper edge of a fin fixed to the framework, said power means being connected to said fin caps, the vibratory motion imparted to the fin caps having both vertical and horizontal components; the vibratory motion imparted to the fin caps of adjacent fin assemblies across each deck being out of phase such that the momentary vertical and horizontal directions of movement thereof are opposed to one another.
5. An apparatus as set out in claim 1 wherein the fin assemblies are mounted to a rigid frame movably suspended above said receiving means and forming part of said framework; said power means being mounted to said frame.
6. An apparatus as set out in claim 1 wherein the fin assemblies are mounted to a rigid frame movably suspended above said receiving means and forming part of said framework; said power means being mounted to said frame, and operatively connected to upright elongated fin caps respectively covering the upper edges of vertical fins fixed to the rigid frame.
7. An apparatus as set out in claim 1 wherein the fin assemblies are mounted to a rigid frame movably suspended above said receiving means and forming part of said framework; said power means being mounted to said frame; said frame being suspended for vertical motion relative to said receiving means while maintaining a constant orientation relative thereto; and lifting means in said framework operatively connected to said frame for adjusting the elevation of the frame relative to said receiving means.
8. The apparatus as set out in claim 1 wherein each deck has twice the number of fin assemblies as the deck immediately above it, with alternate fin assemblies vertically aligned under the fin assemblies of the deck immediately above it.
9. An apparatus for orienting wood strands or the like in parallel directions during deposition of the strands to form a mat, comprising: strand receiving means for supporting strands deposited thereon during formation of a mat; a fixed framework straddling said strand receiving means; a frame moveably mounted to said framework at a location elevationally above the strand receiving means; a plurality of vertical fins mounted to the frame and spaced parallel to one another by a distance less than the length of the wood strands, each fin having an upper edge and a lower edge, the fins being arranged in a plurality of decks vertically stacked one above the other in adjacent locations, each deck containing a multiple of the fins in the deck immediately above it, with correspondingly-spaced fins of each deck being in vertical alignment.
10. An apparatus as set out in claim 9 further comprising: an individual fin cap mounted along the upper edge of each fin and overlapping the side surfaces therEof, said fin caps extending along the full length of the fins and extending upwardly therefrom as a vertical extension of the fins; and power means mounted to the frame and connected to the fin caps for imparting to each fin cap a reciprocating vibratory motion having both vertical and horizontal components.
11. An apparatus as set out in claim 10 wherein adjacent fin caps across each deck are vibrated by separate power means located at opposite ends of the frame, the motion imparted to the adjacent fin caps being out of phase and opposite to one another.
