Including Means To Cause Nonrectilinear Tool Infeed Patents (Class 83/768)
  • Patent number: 4951215
    Abstract: A lineal output measurement circuit adapted for use with product cutting apparatus, primarily with wood cutting apparatus of the type which have a plurality of simultaneously operable cutting elements. This product cutting apparatus is thereby capable of cutting product stock, such as ripping of a wood member simultaneously into individual wood section strips with a plurality of saw blades positioned to cut the individual strips. The apparatus generally includes some form of input mechanism for programming the cutting mechanism to produce the individual sections of product, that is, to produce the desired amount of the selected widths of product. The measurement circuit of the present invention utilizes program electrical signals from the apparatus which provide a program input representative of the different sizes of product sections to be produced, along with a port circuit and a processing means.

  • Patent number: 4947909
    Abstract: A system of optimizing the volume of boards that may be cut from a log provides for one surface of a cant to be cut with a curved or straight surface. This takes into account curved, tapered or straight logs. The system comprises a scanner positioned to scan the log and determine an optimum cut surface profile, a cutting head positioned to cut the top surface of the log, the cutting head having relative vertical movement to the top surface, a conveyor to convey the log passed the scanner and the cutting head, and a controller to control the relative movement of the cutting head in accordance with the signal from the scanner to produce the predetermined optimum cut surface profile for the top surface of the log.

  • Patent number: 4941100
    Abstract: A controller for a head rig edger saw for sawing the edges of a board that is cut from a log by a head saw includes a detector for determining the surface contour of the log to be sawed, along a line displaced from the face of the log; a computer device for selecting an edger saw line through the log from the surface contour to produce a board satisfying predetermined criteria; and an edger saw controller connected to the computing device for providing control signals to the edger for causing the saw to cut the board along the selected line.

  • Patent number: 4926917
    Abstract: A feed speed control for band saws avoids overfeeding and underfeeding of logs or cants to allow higher initial input feeds and takes into account varying cutting depth throughout a log or cant length. The method comprises the steps of positioning a log or cant in preparation for sawing in a saw line, projecting a first light line onto the surface of the log or cant at the projected saw entry line, and a second light line onto the surface of the log or cant at the projected saw exit line and the second light line to determine depth of cut, and controlling the feed speed of the log or cant during the sawing step past the saw blade, to a predetermined feed speed for the measured depth of cut to avoid overfeeding and underfeeding.
