Abstract

907,862. Rotary abrasive tools. PLYMOUTH PRODUCTS CORPORATION. June 27, 1961, No. 23184/61. Class 60. A disc of abrasive sheet material is mounted on a driven backing member comprising a number of radial arms or ribs 24 projecting from the face of a thin sheet-metal disc 20, Figs. 2 and 5, or having the arms 24 unconnected by segmental portions, Fig. 8, in both embodiments the abrasive sheet 26 is unsupported between the arm airs so that cooling air reaches its back surface. In the embodiment of Fig. 2, the segmental portions 40 of the backing member 20 have apertures 44 for the admission of air to the space between the member and the back of the abrasive disc 26 which is held by a screw-head 36 engaging the centre of the disc in a recessed portion of the member 20. The ribs 24 may be of flat or curved cross-section and the outer edges 22 of the segmental portions 40 may be scalloped. In the embodiment of Fig. 8, the arms are of curved cross-section; they may be joined at their outer ends by integrally formed flat arcuate strips forming a peripheral annulus.
