Abstract
The present invention relates to a method for manufacturing a flexible abrasive disc, and to such an abrasive disc. The abrasive disc comprises a backing with an upper side and a lower side. The upper side has an abrasive agent coating for forming a surface layer. In order to form a surface layer as specifically patterned as possible, the backing of each abrasive disc is coated separately. In this manufacturing method, the abrasive agent coating on the upper side of the backing is embossed with an embossing mold specially structured and to be pressed against the backing.
