ABSTRACT:
A method for the continuous marking of elongated material (1) which is moved in its longitudinal direction, by which ring-shaped markings which are limited in axial direction are applied to the surface of the material (1) by means of ink jets (2). The ink jets (2) emerge under pressure from two nozzles (6, 7) which are arranged parallel to each other and swing continuously on a swing shaft (5). If only one nozzle (6) is to function, the other nozzle (7) is closed by a 3/2-way valve (20). At the same time, a bypass (18) is opened through which the quantity of ink intended for the disconnected nozzle (7) is conducted away. The ink jet (2) of the still functioning nozzle (6) is then retained without change.
