Apparatus for the cleaning and sealing of the nozzle surface of an ink head

Abstract

The sealing and cleaning apparatus for an ink head consists of an electromotively driven endless band, on which two wedge-shaped wiping lips are arranged. For cleaning and sealing, the nozzle head is brough a close distance in front of the endless band, a surface of the endless band not provided with wiping lips serving as spraying surface for the squirting-out of the ink head. A cleaning device of wiping edge or cleaning roller removes the ink on the endless band. For covering in breaks in recording, the endless band has, furthermore, a depression formed by bulges, which is brough into contact in front of the nozzle plate or covering. For sealing, a convexly formed flexible pad, which is arranged between the endless belt, is pressed by means of a pressure-applying device against the endless band and cosequently against the nozzle plate. Due to the convex form, no air entrapment can occur in the region of the nozzle plate.
