Abstract: The invention relates to a device for stamping distinguishing marks on parts moving in the feed direction of a roll line, comprising at least one mark-holder for holding a mark, the mark-holder being placed on the circumference of a stamping wheel. The inventive device comprises an eccentric stamping wheel which is mounted so as to rotate in a stamping unit and which can be accelerated in rotation by means of driving mechanism in synchronism with the speed of the parts to be stamped with a distinguishing mark. The stamping wheel applies a force on the parts to be stamped with a distinguishing mark which can be adjusted continuously and constantly. It is possible to adjust the horizontal, vertical and possibly oblique orientation of the stamping position of the stamping wheel. The inventive device is also characterized in that it comprises a range measuring device for the moving parts, which is used to control a horizontal driving mechanism for tracking the stamping unit carrying the stamping wheel.
