Title: Tiefdruckmaschine
IPC: B41F9/10
Filed: 1981-12-23
Granted: 1986-03-13
Abstract: Die Erfindung betrifft eine Tiefdruckmaschine. Der Tiefdruck-Zylinder wird über eine Farbwalze mit Farbe beaufschlagt. Die Überschußfarbe wird durch eine Rakel abgezogen. Im Randbereich des Zylinderumfangs sammeln sich jedoch meist Farbpigmente, die im Laufe der Zeit feste Brocken bilden und beseitigt werden müssen, sofern sie nicht zuvor unkontrolliert abgeschleudert werden. Erfindungsgemäß wird die Ansammlung der Farbpigmente im Randbereich des Zylinderumfangs dadurch verhindert, daß die Randbereiche mit dem in der Druckfarbe enthaltenen Lösungsmittel besprüht werden. Durch dieses Besprühen kann eine kontinuierliche Reinigung der Randbereiche und auch der Stirnflächen des Zylinders erfolgen. Das Lösungsmittel gelangt entsprechend kontinuierlich in die Farbwanne, was günstiger ist als die zeitweise Zugabe größerer Lösungsmittelmengen.
