Abstract
The present invention relates to an abrasive product and to a method of manufacturing same. Such an abrasive product comprises a structured abrasive coating provided on an upper side (6) comprised by the abrasive product. Herein, abrasive grains (8) and glue (7) are molded on a backing such that the upper side of the abrasive product is provided with a three-dimensional product-specific pattern. This pattern is created by said abrasive grains and glue, which constitute an individual composite grain (9). In generating the pattern, a special computer program is utilized in a computer program product for placing said composite grains randomly over the upper side of the abrasive product. The invention also relates to a casting mould with which the thus obtained pattern may be transferred onto the upper side of the abrasive product. The invention further comprises an arrangement for manufacturing said casting mould.
