FIELD: casting production. SUBSTANCE: apparatus for applying a sprinkling material onto blocks of patterns includes a bath with the sprinkling material, having a bottom, made of felt, over which a ring, having a welded bottom of grid, is placed with possibility of vertical motion. The ring is suspended (with use of chains) to a board of the bath. A manifold for feeding compressed air is mounted under the bottom of the bath. The apparatus provides enhanced uniformity of the sprinkling material, being applied on the blocks as a coating of the pattern block along its thickness. EFFECT: enhanced quality of sprinkled coating of patten blocks. 1 cl, 2 dwg
