The invention relates to a spacer tube (3) made of metal, in particular aluminium, for frame or glazing bars of an insulating glazing as spacers or desiccant containers between two continuous glass panes, a coloured strip (2) being printed on the inner wall (5) of the spacer tube (3) which is visible in the insulating glazing, and gas-exchange openings (8) preferably subsequently being incorporated in the inner wall (5). The invention also relates to a method for producing a spacer tube (3), in which a variety of coloured strips (2) are printed, preferably simultaneously, next to one another onto the surface of a metal band (1) using a rotary printing apparatus (17), the colouring material is dried and the metal band is divided longitudinally between the coloured strips and the resulting metal strips are profiled into spacer tubes (3) and cut to length. <IMAGE> |
