Composite reinforced oriented strand board
View Patent ↗The present invention resides in one aspect in a building material that comprises wood and a composite polymeric material that is combined with the wood in a heterogenous admixture. The composite polymeric material incorporates fibers in a polymeric matrix. The fibers can be chopped, continuous, or combinations thereof. In addition, the fibers can be unidirectionally oriented and/or randomly oriented. Suitable fibers for use in the composite polymeric material are glass, polymers, carbon, combinations thereof, and the like. However, the present invention is not limited in this regard as other fibers known to those skilled in the pertinent art to which the invention pertains can be used without departing from the broader aspects of the present invention. Suitable polymeric material for the polymeric matrix include thermoplastic polymers, thermosetting polymers, or a combination of thermosetting and thermoplastic polymers.
1. A method of forming an OSB, the method comprising the steps of:
forming flakes of a composite polymeric material;
positioning the flakes in a bin;
transporting the flakes from the bin to a picker roll using a conveyor;
transporting a substantially uniform mass of the flakes from the picker roll to an orienting deck, the orienting deck comprising a plurality of spaced apart discs rotatably mounted on shafts;
breaking apart clumps of the flakes as the flakes are transported from the picker roll to the orienting deck;
causing the flakes to drop from the orienting deck to a table under the orienting deck; and
pressing the dropped flakes using heat and pressure to form the OSB.
2. The method of claim 1 , further comprising rotating the table to orient the flakes falling from the orienting deck.
3. The method of claim 2 , further comprising controlling the rotating of the table using a programmable logic controller.
4. The method of claim 1 , further comprising moving the table in a rectilinear direction to orient the flakes falling from the orienting deck.
5. The method of claim 4 , further comprising rotating the table.
6. The method of claim 4 , wherein the step of moving the table in the rectilinear direction comprises moving the table on a conveyor.
7. The method of claim 1 wherein the forming of the flakes comprises dividing the flakes into pieces.
8. The method of claim 1 wherein the flakes are formed from a laminate of layers of the composite polymeric material.
9. A method for processing flakes comprising:
forming flakes of a composite polymeric material;
positioning the flakes in a bin;
transporting the flakes from the bin to a picker roll using a conveyor;
transporting a substantially uniform mass of the flakes from the picker roll to an orienting deck, the orienting deck comprising a plurality of spaced apart discs rotatably mounted on shafts;
breaking apart clumps of the flakes as the flakes are transported from the picker roll to the orienting deck;
causing the flakes to drop from the orienting deck to a table under the orienting deck; and
rotating the table to orient the dropped flakes.
