It comprises a spill proof rubbing applicator capable of dispensing chemical substances ranging from low viscosity liquids to fine dry particulate and includes slumes and gels. The tool is provided with means of removing dirty used fibres from its treatment face.

Abstract: A spiral wound abrasive belt is formed from an abrasive media including a plurality of webs. The webs of the abrasive media may include coated abrasives joined by splicing media or other suitable joining material. Alternatively, the webs may include individual single or multiple layers that form a coated abrasive simultaneously along with the spiral belt without the use of additional joining material. A method of forming the spiral belt includes draping the abrasive media over a fixed hub at an angle to form the spiral belt while abutting the edges of the outermost web and overlapping the outermost web and adjacent web or webs. Heat and pressure may be applied to the joined edges to form a strong bond along the spiral seam. Another method includes introducing the webs forming the abrasive media at an angle and draping the webs over a fixed hub. The abrasive media may then be passed around an adjustable hub that provides tension in the spiral belt while allowing for different circumferentially sized belts.

The inner rotating area (11) supports a cylinder-shaped grinding device with several layers of a grinding device support, which are arranged concentrically around the longitudinal axis of the rotating shaft (14). The outer rotating area (12) is provided with radially arranged strip-shaped grinding devices.

Abstract: Perforated sheet steel or wire mesh to which tungsten carbide grit is copper braze welded to provide a device which can be cut to a desired size and shaped into or used as a substrate for tools used for sanding, filing, grinding, deburring, deflashing, cutting, sawing, filing and the like. The sheet steel being perforated provides apertures or recesses wherein removed material can collect and/or pass through reducing the clogging of the grit and frequency of cleaning the working surface of the tool or device. The apertures also provide for the flow of air, cooling the device in certain applications. Tungsten carbide gritted wire mesh is particularly good in providing a surface which tends to renew itself due to grit adhering to the side of the wire strands but not such as to clog the holes. Welding the grit to the wire mesh or cloth also causes the strands of the cloth to be welded together providing for a strong, yet flexible device or substrate.

Abstract: The invention provides an apparatus and a method for forming the end surface of a coaxial composite member consisting of a cylindrical member and an axial member, in which the axial member is ground more readily than the cylindrical member, being capable of forming the end surface of the coaxial member into a convexed spherical mirror surface with high precision, without recession of the axial member from the formed spherical surface.

Abstract: A material adapted for the preparation of a working tool contains long fiberglass arranged in the form of an entwined yarn and at least one thermosettable resin containing abrasive grains dispersed therein, which impregnates the entwined fiberglass yarn. Upon shaping and curing, a working tool is readily formed from this material in the form of any of a rotor, a stick or other desired shape.

Abstract: A polymeric foam finishing pad is made by attaching a dense array of individual foam members to a suitable support substrate. The foam members are individually inserted into a support substrate and attached to the substrate by an adhesive layer. When making the foam pad, each of the foam members is preferably folded and inserted into a preformed opening contained in the support substrate, such that each foam member forms a pair of fingers that extend from the front face of the support substrate. The outer tip of each foam finger may include a pair of slits extending into the foam member from the outer tip.

Abstract: A polymeric foam finishing pad is made by attaching a dense array of individual foam fingers to a suitable backing substrate. The fingers may be individually attached to the substrate or attached to the substrate by an intermediate foam strip to which the fingers are integrally joined. When making a circular rotary buffing pad, the foam strip is preferably attached to the substrate in a spiral pattern.

Abstract: A method and an apparatus for providing an optical fiber connector or similar workpiece formed of, e.g., glass, ceramic or plastic with a mirror-finished convex tip efficiently is disclosed. While a film-like abrasive tool is conveyed in contact with the wall of a groove formed in a stage, the workpiece is caused to rotate about its axis (and to move in a reciprocating motion). By the resulting grinding operation, the sectional shape (arcuate) of the abrasive tool contacting the wall of the groove is transferred to the end of the workpiece. As a result, the end of the workpiece is provided with a convex tip. The abrasive tool is replaced with an abrasive tool for finishing, as needed.

Abstract: A longitudinally extending web of lofty nonwoven abrasive surface treatment material is provided in a coreless roll form to the end user. Successive wraps of the nonwoven abrasive material have interengaging surfaces sufficient to maintain the material in a spirally wrapped configuration yet being readily separable. A plurality of longitudinally spaced and laterally disposed perforations through the web permit the user to successively separate the web into a plurality of sheets of abrasive surface treatment material. In a preferred embodiment, the roll is encased in a protective shrink wrap sheath, and each sheet is separated from the roll by separating said sheet from an innermost wrap of the roll.

Abstract: A process for forming a twisted stem tool uses a specially designed clamping jaw fixture at the nose or bight portion of a half-round wire or cotter pin which helps to reduce the required clamping force and distribute that force over the entire wire-fill material interface. The jaws of the clamping fixture engage the outside of the nose over a substantial area, and in some forms actually bite into the wire or pin. After the twisting operation, the stem is placed in a swaging or coining press, and the stem beyond the fill material is reformed into a three or six-sided drive stem. The cold flow of the metal to form the flat sides locks the twisted half round wire or pin sections together so that the stem will resist unwinding if the tool is driven in a reverse direction. The coining of the stem providing flats provides a tighter confinement of the bundle of fill material at the stem, and enables a common three or six jaw Jacob's style chuck, for example, to obtain a more secure grip.
