NEW ASSEMBLY FOR DRUMS, essentially characterized by the fact that the central ring on which the patches are assembled is obtained in two pieces, the ring of which has perimetral grooves on the outside, intended in one case to contain auxiliary pieces destined to be attached to the patch by intermediate of a glue, and in the second case, to receive under pressure an internal perimetral rib that the tension rings of the patch are provided with, which fix it in its position and force it to an intimate contact with the auxiliary parts on which It must be stuck.
