Date Jun. 10, 1982.A grinding- or polishing implement can be produced by providing a rectangular sheet (1) at both sides with segments (2) formed by slits from the outside towards the center. Hereafter the sheet is folded around the center across a glue string (5), and then the two folding edges are folded together and glued together for the formation of a closed ring. This ring can thereafter be placed on a spindle (6) preferably between retaining discs (8). In this way raw material can be saved in the production of rings, just as the rings can be used more economically in an implement as the grinding qualities are improved through the big number of segments, their completely uniform size and placing along the periphery of the implement and their ability to adjust and shape themselves according to the prepared members. An implement can be produced by disposing such rings between retaining discs (8) on a rotating spindle (6), and in order to secure the rings the spindle (6) can at its end have one or more guide facings (10), in which a co-operating guide pin (12) on a disc (7) can slide and be axially displaced by being tightened together with a bolt (11).
