Double sided covered pulsatile instrument e.g. drum, has mounting rings arranged such that clamping devices are guided over bulge by the respective rings or at rings to mutually compensate force acting on bulge themselves

摘要

The instrument has two mounting rings (1) that are pressed against a bulge (5) machined from a bowl (4) or fastened at the bowl during clamping skins by clamping devices (6). The rings are arranged such that the clamping devices are guided over the bulge by the respective rings or at the rings to mutually compensate force acting on the bulge themselves. The clamping devices are fastened to individual ring segments or counter bearings.
