An impact roller and a method of imparting impact blows cyclically to a surface.

摘要

The roller has flail member (14) pivotally connected to a roller (10) and also has recesses (17) to accommodate the flail members when inoperative. In operation, when the roller (10) rolls along a surface (13), the flail members (14) fall forwardly under gravity and impart cyclic downward blows to the surface (13) over which the roller (10) is rolling. Upon faster rolling of the roller (10), the magnitude of the blows increases under the action of centrifugal force.
