Abstract

907,260. Abrasive tools. MINNESOTA MINING & MANUFACTURING CO. Jan. 22, 1959 [Jan. 24, 1958], No. 2426/59. Addition to 846,568. Class 60. A method of forming the abrasive flap wheel claimed in the parent Specification comprises (1) forming a block of superimposed abrasive sheet flap sections, each flap section having at least one pair of opposed notches in the lateral edges adjacent one end thereof with said notches aligning to define opposed grooves in the lateral surfaces of the block, (2) applying flexible stretchable binding means about the block with said binding means extending in and along each of the grooves thereby to unify the block, and (3) manipulating the unified block into an annulus with the ends of the flap sections adjacent the notches forming the inner periphery thereof. After manipulation into the annulus, an annular side flange having a central hole of lesser diameter than the inner diameter of the annulus is applied to one face of the annulus so that a laterally extending ring adjacent the outer periphery of the flange enters one groove, the elastic member is cut and removed, and another flange similar to the first is applied to the other face of the annulus. The annulus is then rotated about a horizontal axis. Liquid curable adhesive resin is supplied through the centre hole of one side flange and flows under centrifugal force radially outwards between the flap sections to the desired amount. The resin is then cured, preferably by heat, e.g. by a cartridge heater. The side flanges may remain or may be removed.
