Method for Processing a Molded Tray Based on Bamboo-Wood Mixed Shavings
The present invention provides a method for processing a molded tray based on bamboo-wood mixed shavings, comprising: extracting, crushing, mixing, drying, separating by wind separation, heat balance treatment, mixing glue, paving and hot pressing, cooling and grinding, inspecting and warehousing. In the invention, the industrial trays are manufactured by mixed bamboo and wood materials. The bamboo materials do not include bamboo peels and other impurities. The use of bamboo materials can improve the quality of trays from raw materials and reduce the moisture content of the trays. In addition, the brittleness of bamboo materials can improve the hardness of trays. The combined bamboo materials and wood materials can increase the toughness of the product and reduce the cost; furthermore, each link in the production process is elaborately designed and adjusted in the invention. The industrial trays made by the processing method of the present invention have increased the weight supporting capacity by at least 1.5 times compared to ordinary trays, and the product's service life is 3 to 5 years in normal uses (no water soaking, no overpressure).

Strand orientation system and method
A system for orienting strands (e.g., wood strands) includes multiple rotatable shafts that extend perpendicular to a travel direction of a mat of aligned strands. Each shaft can include axially spaced agitation members that extend radially away from the shaft, such as in a direction parallel to the travel direction. A vane set can be positioned vertically below the shafts. The vane set can include multiple partitions that define inter-partition spacings parallel to the travel direction. In an example, an inter-partition spacing of the vane set can be greater along a bottom portion of adjacent partitions than along a top portion of the same adjacent partitions. In an example, an upper edge thickness of a partition can be greater than a lower edge thickness of the same partition.
POROUS PAPER SHEET, AND DEVICE AND METHOD OF MANUFACTURING SAME
A porous paper sheet includes a first base material; and paper pieces laminated on the first base material, and adhered to each other or adhered to the first base material using an adhesive such that the paper pieces have predetermined pores therebetween. The paper pieces are shredded in a predetermined size. A device for manufacturing the porous paper sheet, includes: a first base material feeder feeding a first base material; a conveyor unit including a conveyor belt on which the first base material is placed and rollers driving the conveyor belt; an adhesive nozzle positioned above the conveyor belt and applying an adhesive to the first base material; and a paper piece feeder positioned above the conveyor belt and feeding paper pieces to the first base material.
SHEET MANUFACTURING APPARATUS, AND SHEET MANUFACTURING METHOD
A sheet manufacturing apparatus suppresses material being left in a material supply conduit while manufacturing sheets with uniform grammage. A sheet manufacturing apparatus includes: a rotatable, foraminous drum unit; a web forming unit configured to form a web using material including fiber that has passed through the holes in the drum unit; and a material supply conduit having a connector that connects to the drum unit, and carrying material including fiber into the drum unit by air flow; the velocity of the flow in the connector being lower than the velocity of the flow on the upstream side of the connector.
System for the production of panels made of wood flakes
A system for production of panels, particularly for the production of panels made of wood flakes comprising at least a support plane movable along a direction of forward movement, at least a first and a second forming machine arranged in succession to one another along the direction of forward movement above the support plane and each comprising at least a first set of distributor elements rotatable around respective axes, the distributor elements being able to select a flow of wooden material comprising short flakes and long flakes so as to allow the fall of the short flakes on the support plane and the dragging of the long flakes, where the first forming machine and the second forming machine comprise at least a second set of distributor elements operable independently of the relative first set and where the distributor elements of the first set are operable in rotation in both directions.
