Abstract
An impact rapping device includes a stationary anvil integrated with a surface to be rapped, the anvil having a hammering axis perpendicular to the surface to rapped, a hammer arranged to move coaxially with the hammering axis, to hit an impact surface of the anvil, and a device for moving the hammer. The anvil and the hammer form a compact unit, which can be assembled in any position. The hammer is supported to lean on the anvil in such a way that the position of the hammer automatically follows changes of place or position of the anvil, and so that the hammer can move only parallel to the hammering axis.
