Zusammenfassung: | A device for supplying a print bar (10) with ink has a distributor tank (16) that is connected with all print heads (12). Degassed and tempered ink is supplied to the distributor tank (16). In the distributor tank (16), a ring line (36) extends through which flows ink at the nominal temperature, and the ink (19) in the distributor tank (16) is thereby tempered. In addition to this, the distributor tank (16) has a supply line (38) via which fresh ink may be fed into the distributor tank (16). A changeover switch (42) switches between the two lines depending on the negative pressure in the distributor tank (16). |
