or to Claims. (CI. 51-190) Object of my invention is a grinding tool. It consists in a rotatable device which may be of a cylindrical or drum-like construction and which is provided with flexible or elastic grinding elements. These flexible grinding elements may be madeof threads; ribbons, leaves, blades, tubes or such like formations which themselves may be manufactured from the usual pulverulent or granular grinding materials such as silicon car- 'bide, corundum,j emery, and elastic binders such as rubber, caoutchouc or mixtures of, for in.- stance, caoutchouc with additional substances, for instance, glue. These grinding elements may contain flexible supports or stifl'enings inside,

such as threads, flexible wires, paper, fabrics, flexible metal sheets or metal fabrics or the like. The flexible grinding elements are flxed onto the rotatable supporting bodies which may have the shape of a wheeLcylinder, drum or the like with advantage in a radial position. "lhey may, however, be flxed also in a different position.

The annexed drawing illustrates some manners in which my invention may be carried into practice.

Figure 1 shows a grinding tool which consists of a cylindrical rotatablebody a, on the cylinder jacket of which are arranged thread-like grinding elements b in a radial direction.

Figures 2 and 3 illustrate a grinding tool the cylinder jacket of the wheeior disc-like rotatable body a of which is equipped with leaf-like grinding elements in a radial direction.

In Figure 4 the leaf-like grinding elements c are flxed to the cylinder Jacket in such a position that they are arranged in an angle with the axle d.

Figure 5 shows a tool in which on an axle it several rotatable bodies are provided which carry flexible grinding elements.

The rotatable bodies forming the support of the actual grinding elements may be formed in various ways. They may have, for instance, spherical, hemispherical or conical form or be shaped like an egg or the like.

Figure 6 illustrates a form in which my invention may be carried out which consists of an oval rotatable body flxed onto the axle d, the rotatable body being provided with thread-like grinding elements.

The flexible grinding elements may consist of threads of diiferent sizes and may be manufactured of grinding material and elastic binders and may contain if desired flexible central parts and may be produced by pressing a plastic mixture of grinding and binding material through nozzles.

The plane shaped leaf-like grinding elements may have, for instance. a rectangular, square, so rhomboid or circular form and may be adapted by their formation to special application purposes.

The thickness of the grinding elements may be varied according to the application they are intended for. They have to be adapted, how- 5 ever, in such a way that each single element retains the'required flexibility. When the rotatable bodies are rotated the flexible grinding elements take up under the influence oi the centrifugal force a position which is in general vertical 10 to the rotatory axle. They form then a very flexible ring or the like which easily adapts itself to the unevennesses of any article on which it is applied.

Grinding tools according to my invention may 15 be utilized for grinding straight and, especially, curved surfaces. They are of special advantage for working upon articles the surface of which has edges, recesses, grooves or the like. They are, furthermore, especially suitable for working on 20 materials which cannot be worked upon with rigid grinding tools such as articles of lead, aluminium, leather, wood or the like. I

What I claim is: l. A rotatable grinding tool which consists in 25 a rotary carrier on the surface of which are flxed flexible grinding elements in the shape of threads made of grinding material and an elastic binder of elastic material, the whole appliance being mounted on a drive shaft. 30

2. A rotary grinding tool comprising a rotatable support, and a plurality of relatively thin, flexible grinding elements secured to said support and extending therefrom, said elements being movable relative to each other and being 35 composed of an abrasive material and an elastic binder.

3. A rotary grinding tool comprising a rotatable support, and a plurality of relatively thin, flexible grinding elements in the shape of threads 40 secured to said support and extending therefrom, said elements being movable relative to each other andbeing composed of an abrasive material and an elastic binder.

4. A rotary grinding tool comprising a rotat- 45 able support, and a plurality of relatively thin, flexible grinding elements in the shape of strips secured to said support and extending therefrom, said elements being movable relative to each other and being composed of an abrasive mate- 50 rial and an elastic binder.

5. A rotary grinding tool comprising a rotatable support, and a plurality of relatively thin; flexible grinding elements in the shape of strips secured o said support with their longer dimen- 55 sion sub=.tantially parallel to the axis thereof and extending therefrom, said elements being mow able relative to each other and being composed of an abrasive material and an elastic binder.
