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.
