Abstract

A print bar for inkjet printing includes print heads disposed in a row, adjustment devices for adjusting the print heads relative to one another in which each of the adjustment devices includes at least one screw and at least one shaft for rotating the at least one screw, and a compensation coupling interconnecting the screw and the shaft. The compensation coupling includes a first coupling half and a second coupling half configured to fit together under elastic deformation. The first coupling half includes spring claws having a first pitch and the first coupling half is disposed on the shaft. The second coupling half including a toothing having a second pitch and the second coupling half is disposed on the screw. The first and second pitches differ from one another.
