An alert allows an operator to reinstall the article. As another example, the abrading article may be sensed to determine whether splicing tape is present to hold two pieces of abrading tape together. The article may be advanced until the splicing tape is beyond an abrading zone. As another example, the abrading article may be sensed to determine whether the abrading article has stopped moving while the article drive is advancing because the article has broken.

  • Patent number: 6893329
    Abstract: An abrasive tape is supplied to a tape head by a tape supply unit and taken up from the tape head by a tape take-up unit. The tape head presses the abrasive tape against a surface of an object under polish, which is rotated by a rotating unit. A tape head pressuring unit utilizes a voice coil motor, for example. Since the tape head pressuring unit generates a pressuring force for pressuring the tape head using the electromagnetic force, it is able to set a minute pressuring force by controlling a drive signal, and to obtain the fine adjustment of the pressuring force easily by controlling the electric signal. Therefore, it becomes possible to press the abrasive tape against the surface of the object under polish with a desired low pressure.

  • Patent number: 6361421
    Abstract: The invention relates to a belt grinder of which the supporting tables (13, 14) are arranged in relation to the grinding unit (11) and hence the grinding belt (12) in such a way that tables need not be adjusted at the same time as the grinding unit is pivoted, while nevertheless the gap (z) between the grinding unit and the edges of the tables remains minimal. Such an arrangement is obtained if the value one minus the cosine of half the maximum pivoting angle (y) multiplied by the direct distance (d) between the tables edges is divided by two and the cosine of half the maximum pivoting angle (y) and gives a result acceptable for practical use and compliance with the standards and safety specifications for the gap (z) between the table edges and the grinding unit.

  • Patent number: 6068542
    Abstract: A surface polishing method comprises allowing a holder to hold a flat sheet-like workpiece, placing a pad tape in a location opposite to the holder, the pad tape consisting of a tape substrate and grains bonded to the substrate surface, supplying free grains between the holder and the pad tape, and rotating the holder and/or a mechanism holding the tape, thereby causing the free grains to polish the workpiece. An apparatus for practicing the method comprises a holder capable of holding a flat sheet-like workpiece, a tape holding mechanism located opposite to the surface of the workpiece and carrying a pad tape which consists of a tape substrate and grains bonded to the substrate, a rotary mechanism for rotating the holder and/or the tape holding mechanism, and an abrasive supplying mechanism for supplying free grains between the surface of the workpiece and the pad tape.

  • Patent number: 5871394
    Abstract: A floor sander having a number of interchangeable sanding head assemblies for sanding a surface such as a hardwood floor. Each of the interchangeable sanding head assemblies includes a sanding implement which may provide differing levels of sanding or other surface action. The desired sanding head assembly is attached with a main housing of the floor sander using a connect assembly attached to each of the sanding head assemblies. A plurality of locking devices mounted within each connect assembly engages an equal number of locking pins extending from the main housing to secure the sanding head assembly to the main housing. An alignment device is provided on the main housing to insure proper alignment of each sanding head assembly with both the drive motor and the surface to be sanded.

  • Patent number: 5584752
    Abstract: A pair of supporting arms are rotatably attached to both ends of a fixed shaft. A supporting shaft extends across forward ends of the supporting arms and in parallel to the fixed shaft. A grinding roller on which an abrasive tape is arranged, and guide rollers sandwiching it are attached to this shaft. Axial centers of the grinding roller and the guide rollers are in an eccentric state. Thus when the guide rollers contact a color filter, a gap is given between the grinding roller and the color filter, and projections can be ground corresponding to the gap.

  • Patent number: 5569063
    Abstract: A polishing apparatus, for polishing/cleaning a target object surface by using a polishing tape, has a spindle rotatably placed inside an opening formed in a base plate, a motor for rotating the spindle, a compression roller rotatably supported between a pair of side walls attached to the spindle, supply and take-up rollers supported rotatably by the side walls for advancing the polishing tape, and a motor for the take-up roller. The polishing tape is supplied from the supply roller and taken up by the take-up roller through the compression roller, while rotating around with the spindle. The compression roller has a smaller diameter at its center part than at its end parts for preventing the polishing tape from becoming twisted or wrinkled when the compression roller is rotated by the motion of the spindle while being pressed against a target object and being advanced from the supply roller to the take-up roller.

  • Patent number: 5359813
    Abstract: A locking mechanism for the contouring head assembly of a belt grinding machine that employs multiple, parallel, abrasive grinding belts, and back-up shoes for pressing the belts against the surfaces on a workpiece to be ground. The locking mechanism secures the contouring head assembly to the bed of the grinding machine. The locking mechanism includes a protrusion, such as a ball, that is carried by the contouring head assembly and a pivotable arm with a socket defined near its free end. The pivotable arm is secured to a shaft that is driven by a rotary actuator, that is powered by a hydraulic motor. The socket engages the protrusion to securely support one side of the contouring feed assembly. A hydraulic cylinder forces a tapered plunger against the pivotable arm to enhance the locking action.
