In a print group for an ink printing apparatus, a housing is provided with print bars comprising print heads. The print bars are moveable independently of one another in a vertical direction from a printing position adjacent to a printing substrate into a park position and back. A protective flap bar for each print bar is provided which is pivotable and which is open to one side. The protective flap bar is arranged in a vertical position next to the print bar in the printing position such that the open side is facing away from the print bar. The protective flap bar is arranged in a horizontal position with the open side upward in the park position such that the print bar is engaged with its print head side in the protective flap bar.

Print group for an ink printing apparatus

In a print group for an inkjet printing apparatus a printing unit is provided comprising a housing with print bars having print heads. A transport unit is provided for a printing substrate. Drive and guidance units are arranged per print bar which move the print bars independently of one another in a perpendicular direction from a printing position into a transport position and back. In a park unit racks are provided for protective cap bars. A protective cap bar is provided per print bar which when coupled to said print bar seals it. Print bars in an operating position not provided for printing are in the transport position and are coupled with associated protective cap bars. Print bars in said operating position for printing are in the printing position and their associated protective cap bars are arranged in the park unit racks.

Print group for an inkjet printing apparatus

In a print bar system or method in which at least one print bar is positioned in a printing position, first and second drive and guidance units are provided for the print bar and which each have an adjustable guidance unit and a first coupling unit. The print bar has print bar receptacles with adjustable positioning pins. The guidance units and the print bar receptacles are designed such that upon insertion of the print bar into the drive and guidance units the print bar receptacles rest in a floating bearing on the guidance units and are centered and arrested after displacement of the guidance units in the drive and guidance units such that the print bar is positioned into the printing position in the drive and guidance units and wherein the positioning pins engage in the first coupling units.
