  • Patent number: 6298275
    Abstract: A part identification system for non-intrusively identifying a subset of parts cut from a sheet material. The part identification system includes a visual signal generator for projecting an identifying image associated with a given subset of cut parts. A labelling program accesses a database, generates a control signal including the part location and identifying image and sends the signal to a controller. The controller directs the identifying image from the visual signal generator to identify the cut parts.

  • Patent number: 6192777
    Abstract: An apparatus and method for cutting pieces of material from a workpiece, such as a web of patterned fabric, which includes irregularities or which is misaligned with respect to a coordinate system of the cutting apparatus. The workpiece is spread on a cutting table where it is cut by a numerically controlled cutter in accord with an electronic marker stored in the cutter controller. The marker is matched to the workpiece and appropriate adjustments are made to the marker before the workpiece is cut. A laser, operatively connected to the controller, projects a match target onto the workpiece at a point corresponding to a selected point on the marker. The marker is then adjusted such that the selected point coincides with a desired location on the workpiece. Adjustment is achieved by electronically displacing the match target from a non preferred location to a preferred one. Software in the controller translates this displacement into appropriate adjustments to the marker.

  • Patent number: 6160563
    Abstract: A coiled ink supply tube for an X, Y plotter and the like is connected between an ink reservoir and a pen mounted within a pen holder and moveable with the pen holder between a raised non-drawing position and a lowered drawing position for drawing lines or graphics on receiving surfaces. The ink supply tube defines a preformed coil having 11/4 turns or windings in the form of a helix with substantially zero spacing between turns. The ink supply tube also defines a straight inlet section coupled between the coil and the reservoir and oriented parallel to the axis of the coil, and a straight outlet section substantially coaxial with a vertical axis of the pen and lying in a plane substantially perpendicular to the axis of the coil. As the pen moves up and down between the raised non-drawing and lowered drawing positions, the diameter of the helical coil changes very little and substantially no lateral forces are imposed by the ink supply tube on the pen.

  • Patent number: 5831857
    Abstract: A pattern alignment system for use during the garment development process prior to the cutting operation includes a table with work surface. There is a digitizer located with the surface. The operator establishes a perimeter of a hide or other fabric piece that has been positioned on the surface with a stylus that presents position signals to a controller in real time. The controller has signals corresponding to a marker and further includes algorithms to compose the drawn lines or points into an electronic representation of the piece perimeter. Defects, textures or the like in the piece are identified in a similar manner. The system includes algorithms which enable the operator to reposition one or more garment segment patterns in the marker to avoid defects or otherwise optimize the segment position on the piece.

  • Patent number: 5806390
    Abstract: A method for cutting sheet material allows multiple layups of sheet material to be cut in side-by-side or stacked relationship on the cutting table of a computer controlled cutting machine. A different marker or array of pattern pieces can be cut from each of the stacked layups. Also, for certain layups, whether stacked or not, markers are located with reference to the centerline of the layup to insure that the pattern pieces of the marker are cut symmetrically or in alignment with ornamentation or designs in the material. An origin point is located at a known position with respect to the sides and ends of the marker. The origin point of the marker is then registered relative to the cutting table and the centerline of the layup.

  • Patent number: 5780805
    Abstract: A method and apparatus for cleaning a support surface during successive cuts of a sheet material along a common cutting path by a laser. The method includes offsetting the location of the common cutting path with respect to the support surface for subsequent cuts. The offset distance is sufficient to align a portion of the common cutting path with a portion of the ridge of debris formed during a previous cut such that upon tracing the subsequent path with the laser, the previously formed ridge of debris is ablated.
