Abstract: In a state that a reference plane of a cutter holder, to which a cutter blade is attached, is brought into contact with a surface of a base of a supporting adhesive tape, the cutter blade cuts the supporting adhesive tape while the reference plane of the cutter holder follows the surface of the base. Herein, a cutting edge of the cutter blade passes by a joining interface between the supporting adhesive tape and a ring frame without penetrating through an adhesive layer of the supporting adhesive tape.

Abstract: Disclosed is a laser guidance system for diamond wire stone cutting apparatus. The laser guidance system includes a targeting laser light source that is fitted to one of two wire guide wheels between which the cutting wire extends and travels. A photo sensor with laser beam detectors is attached to the other wire guide wheel. During ideal operation of the cutting apparatus, the laser beam shines through the kerf in the stone being cut. When the kerf is linearly straight, as intended, the laser beam will be clearly detected by the laser beam detectors. When the kerf is not straight, the laser beam will be at least partially obscured across the cutting span, and the laser beam detectors will detect the lack of full intensity and report this to a controller so as to indicate that adjustments are necessary to re-straighten the kerf.

The pieces of veneer are fed into a cutter by means of a first conveyor belt actuated by a control means which detects flaws in the wood to cut out transverse strips containing the flaws that are then automatically discarded as they come off the cutter. Strips free from defects are then sent on by a second conveyor belt to a deflector which distributes the strips onto two conveyor belts with intermittent movement so as to arrange the strips into compact adjacent groups to form a sheet of desired length. The plurality of adjacent strips forming a sheet are then sent to stackers to form layers of the sheets.

Abstract: An apparatus for feeding sheets comprises a variable speed conveyor for feeding a sheet cut from a web. A high speed conveyor receives the sheet fed by the variable speed conveyor, and feeds it at a high speed v1. A cutting completion detector detects the separation of the sheet from a cutter and generates a detection signal. A controller adjusts the feeding speed of the variable speed conveyor to a feed speed v2 as long as the leading portion of the web is being fed to the cutter, adjusts the feeding speed to a speed v0 (v0<v1, v2), at which the sheet is kept stationary with respect to the cutter, during the time from when the cutter starts cutting the web to when the cutting is finished and the cut sheet separates from the cutter, and increases the feeding speed from the speed v0 to the speed v1 during the time from when the detection signal is generated to when the sheet arrives at the high speed conveyor.

Abstract: A defect detection system is especially applicable to string type potatoes for removing the black spots and includes removing or sorting out potatoes with black spots. It includes a pair of line scanning cameras focused on opposite sides of a vertical on a common line, spaced above the conveyor belt to the height of the potato. Such opposite sight lines provide for effective sensing of leading or trailing edges of the potato. To provide for effective cutting, the cutting blade units have offset blades to allow overlap and a spacing so that areas of uncertainty created by the two cameras are eliminated. To minimize down-time of the system, the vision light, power and punch modules are separately removable. Moreover, they are located on a cantilevered base above the moving belt. This cantilevering in conjunction with pivoted supports allows for a seamless belt and easy removal of that belt.
