Process for producing abrasive tape reels, comprising the step of spreading (SI) a layer of a base adhesive resin on a flexible support (F), the step of distributing or scattering (D) abrasive granules thereon using one or more templates (M) suited to obtain the selective deposition of the abrasive granules on areas delimited by strips without abrasive granules, the step of drying (El) the resin with the consequent adhesion of the abrasive granules, the step of spreading (S2) a second bonding resin layer, the step of drying (E2) the second resin layer. The abrasive granules are deposited on rhomboidal, triangular, rectangular, hexagonal, polygonal, elliptic areas. |
