Abstract:
An apparatus for marking a surface of parts moving on a roller table in a travelling direction at a predetermined speed, which comprises(a) a stamping unit displaceable against an infinitely adjustable force transversely to the surface of the parts to be marked,(b) a drive for adjusting the stamping unit perpendicularly to the travelling direction and parallel to the surface of the parts to be marked,(c) a measuring device controlling the adjusting drive in response to a measured transverse distance between the stamping unit and the parts to be marked,(d) an eccentric stamping wheel carrying on its circumference a character carrier for at least one character and rotatable in the stamping unit about an axis of rotation extending perpendicularly to the travelling direction and parallel to the surface of the parts to be marked, the stamping wheel having a cylindrical surface eccentric to the axis of rotation, and(e) a drive for rotating the stamping wheel at a high speed of acceleration and synchronously to the speed of the parts moving in the travelling direction about the axis of rotation.
