<p>A banded grinder for working edges of slabs of marble, granite and the like, comprising a main body (1) keyable on a rotary chuck (2) and having a lateral surface (3) which is shaped complementarily to an edge (4) of a slab (5). The grinder (10) comprises a length of abrasive tape (6), arranged to superpose the lateral surface (3) of the main body (1), ring-wound about said main body (1) and closed at opposite ends (7). The grinder further comprises a layer (11) of elastically deformable material inpterpositioned between and adherent to the lateral surface (3) of the main body (1) and the length of abrasive tape (6) and rendering the main body (1) and the abrasive tape (6) reciprocally solidly constrained. The layer (11) of elastically deformable material covers the opposite ends (7) and the cut lateral edges (9) of the abrasive tape (6), incorporating both in a banded strip (12) having a continuous abrasive surface (16). <IMAGE></p> |
