Abstract

Zum automatischen Steuern des Materialflusses in einer Beschichtungsanlage wird deren Ringleitung (20) in Beschichtungspausen stromabwärts von zu den Beschichtungsvorrichtungen (25,26,28,29) führenden Hinlaufleitungen (32,32',34,34') gesperrt und das Beschichtungsmaterial aus den Hinlaufleitungen (32,32',34,34') durch eine separate Rücklaufleitung (35,35') hinter der Sperrstelle wieder in die Ringleitung (20) zurückgeleitet.

Figure 00000001
For automatic control of the material flow in a coating system, the ring line (20) is blocked during coating breaks downstream of the feed lines (32, 32 ', 34, 34') leading to the coating devices (25, 26, 28, 29) and the coating material from the feed lines (32,32 ', 34,34') through a separate return line (35,35 ') behind the blocking point back into the ring line (20).
