SPECIFICATION for the Foreign Patent Application TITLE OF THE INVENTION METHOD OF PRODUCING GRINDING TOOL AND APPARATUS FOR PRODUCING SAME ABSTRACT OF THE DISCLOSURE The present invention relates to a grinding tool comprising a large number of grinding sheets radially arranged and collected to be adhered to each other in a disk-like shape. A disk provided with a through hole at a center thereof, to whose upper surface adhesives are applied at pointed palces of a circumferential edge portion of the upper portion of the disk, or, on which heat sensitive adhesives are overlapped, is supplied on a receiving seat of normal temperature or heated. And, a large number of long grinding belts are sent toward the center of the above described disk at appointed strokes so that a grinding particle surface may exist upside and side edges thereof may be overlapped to each other. A cap plate is brought down on the grinding belts radially arranged by sending them in the above described manner to fixedly press inner ends of the respective grinding belts against the circumferential edge portion of the disk and the respective grinding belts are cut in a circular shape coaxial with the disk at a suitable position of an outer side of the disk. In addition, in the case where the adhesives on the disk are heat sensitive, a heated pressing member is used to pressurize. Then, the respective grinding belts are cut in the circular shape coaxial with the disk at the suitable position of the outer side of the disk followed by releasing the pressing of the pressing plate or the pressing member against the disk to remove the disk from the receiving seat.
