摘要

The drum (1) has a cylindrical casing (2) provided with tide holes (3) and ribs (4), where the ribs are implemented in form of distance lying elevations. The elevations are implemented in spherical shape with a spherical vertex, where a base area of the elevations is implemented in a cylinder form. The elevations are arranged in parallel rows to a rotation axis, so that the elevations of the adjacent lying rows are displaced on a half step along the axle. The elevations are implemented from a material e.g. plastic, with low friction coefficient.
