  • Patent number: 11511391
    Abstract: A surface processing device, in particular a manual grinding device, includes a processing body which has at least one processing surface for grinding or polishing a workpiece surface, wherein inlet openings are arranged on the at least one processing surface for suctioning off dust-laden dust air and these inlet openings are flow-connected via a duct arrangement to a suction connection to which a suction device can be connected. The surface processing device is provided with an adjustment means for adjustment of effective flow cross-sections, with which inlet openings of a first processing surface section of the at least one processing surface and inlet openings of at least one second processing surface section of the at least one processing surface are flow-connected to the suction connection, so that a suction effect on the first processing surface section and the at least one second processing surface section can be set and/or switched off.

  • Patent number: 10611000
    Abstract: A flexible sanding apparatus that utilizes a hook-and-loop fastener for attaching sandpaper to an elastomeric body is described. The sanding apparatus may include an elastomeric body with a thin, relatively flat spring member attached to a bottom surface of the elastomeric body. A first component of the hook-and-loop fastener may be coupled to the elastomeric body while being positioned in a recessed portion on the bottom surface of the elastomeric body. A second component of the hook-and-loop fastener with a sanding surface may be attached to the first component.

  • Patent number: 6852021
    Abstract: A method of making an abrading implement includes the steps of disposing a porous member for aiding in abrasion adjacent a first surface within a mold and supplying two reactive liquid components into the mold in a manner in which the two materials enter onto a second surface of the mold opposing the first surface, whereupon a reaction between the components form a raw implement of structural foam which is bonded to the porous member. Subsequent the reaction, the raw implement is removed from the mold and cut, preferably sawn, in a manner to provide an abrasive implement having a surface portion the foam exposed from the cut to aid in gripping the same by one's hand. An abrading implement is also provided by the method.

  • Patent number: 6682400
    Abstract: A sanding device for use with abrasive sheet material. The device has a body with a rounded side for sanding concave recesses, sharp corner edges for use in sanding ninety-degree corners, and flat surfaces for sanding planar areas. Abrasive sheet material is attached to the body by an anchor strip which fits into a groove in the body to cause a friction fit.
