<p>The brush-type massage instrument has a frame containing one or more rollers. Each roller is equipped with brushes, whose bristles extend radially. The distance between the roller centre and the bristle tips can be less at the middle of the roller, increasing towards the ends. The brushes can be mounted in rows spaced round the periphery, there being a pair in each row in line in the axial direction. Each consists of a holder detachable from the roller, in which the bristles are mounted. As an alternative, there can be a holder extending around the roller in a spiral.</p> |
