  • Patent number: 6997692
    Abstract: The method and apparatus for forming composite wood products particularly composite veneer like products which may be intermediate products and laminated to form the final composite product. Strands are fed from a source of supply at a metered rate, entrained in an air stream and carried along a confined path between an entrainment zone and the source of supply. Strands are condensed onto a surface to form a veneer lay-up of at least one layer of strands on the forming surface and this veneer lay-up is carried from the path and deposited onto a collecting surface and later consolidated into a composite product. Entraining air and strands not forming veneer are separated in the supply station, the strands fall onto the supply of strands and energy is added to the separated entraining air and it is returned to the entraining zone.

  • Patent number: 5875328
    Abstract: Operation for each action of a machine is individually controlled by providing a file of set of components necessary to carry out the operation and a file of a set of components that are available and then determining in sequence whether each required component is also available and transferring those components that are both required and available in sequence to a fault file. The fault file may then be read in sequence and used to control the action being controlled so that if anyone of the required components is not available, the fault file so indicates and terminates the operation based on the first component found to be inoperative so that it is an easy matter to define the source of the problem.

  • Patent number: 5859780
    Abstract: A control for delivery system made up of a plurality of variable output feed sources each with an independently variable input of material defines the capability of each of the feed sources based on the level of material and combines these capabilities to define a total capability of the delivery system. An output setpoint for each source is determined based on its capability and a required setpoint is set based on a desired end product characteristic which is used to define a production rate based on total capacity, required setpoint and the production line characteristics. The process is iterative so that the production rate, e.g. speed of the line is varied iteratively depending on the then current capabilities of the feed sources of the system and the footprint of the feed sources are adjusted based on their sensed capabilities thereby to maximize production line speed based on capability.

  • Patent number: 5740898
    Abstract: Strand lay-up system produces a layered strand lay-up from separate feed bins and then deposits incremental lengths of the so formed layered lay-up over discrete selected area to form a more homogenous lay-up.
