ABSTRACT:
In a grooved drum with a working drum surface of metal consisting of a cylindrical inner drum on which at least one ribbon is helically wound, turn by turn, the radially outer boundary of which forms the working drum surface, the ribbon also forming axially extending circumferential grooves, adjacent turns of the ribbon are connected to each other in a form locking manner on their sides facing each other in the axial direction causing the adjoining turns to be immovably fixed relative to each other so that in the event of a break in the ribbon the turns will not give in to the circumferential tension force generated during winding and burst open.
