  • Patent number: 5791215
    Abstract: Precise cutting of pattern strips and pattern pieces from lace and similar patterned fabrics requires correct mutual positioning of the fabric and fabric cutter for precise alignment with the boundary of the pattern pre-existing on the fabric. Patterned fabrics and especially loosely-woven lace are liable to randomly variable stretching and slippage which makes it impossible to cut under the direction of an externally imposed pattern program without regard to the instantaneous location of the pattern pre-existing on the fabric. The invention comprises lace-cutting apparatus and a lace-cutting method including optical scanning of the lace, recognition of the pattern boundary, and mutual alignment of the fabric with the fabric cutter to trace the intended cut line. Different techniques for mutual movement of the fabric and cutter are employed according to whether the pattern boundary is re-entrant or not. Preferred forms of fabric cutter include a hot-wire cutter and a laser beam cutter.

The sawing apparatus includes a continuous flexible band saw blade, provided with teeth at one or both edges. A support exposes a section of saw blade that is curved and stabilized by the use of electromagnetic fields in cooperation with rollers. The saw is then configured to make a cut of a desired thickness in a curve parallel the growth rings of a log, in an arc which minimizes the number of knot defects in the board. With each pass of the log through the saw, or vice-versa, a new arc section is cut, and the log or the saw is rotated and positioned for the next arc section cut. Plural sawing stations may be used in series, and the process may be run bi-directionally when using double-edged saw blades. Once the board sections are cut, they are flattened under pressure in a kiln.

  • Patent number: 4977805
    Abstract: An edging apparatus edges a wood board to achieve a desired rounding effect under a rounding rule of the lumber industry. A positioning apparatus positions and holds two edging saws, and the positions of the saws are initially controlled by an operator who selects initial cut positions. Input data, including board length and thickness parameters and the initial cut positions are generated by input devices and a computer is responsive to the input data for computing the best cut positions of the saws. In making this computation, the computer takes into consideration the rounding rule and, according to predetermined criteria, the computer selects best cut positions that will produce an edged board whose measurement exceeds a whole board foot measurement by a desired fraction of a board foot. Adjustment input may be provided to adjust the size of the desired fraction of the board foot.
