ABSTRACT:
A turner bar has an outer surface having a profile shaped for enabling air cushions to be built up between the outer surface and a printed material web which is fed around the turner bar. In addition, or as an alternative, a guide plate or an aerofoil profile may be arranged on the turner bar for creating the air cushion. Air may also be fed from radial holes or from holes in a guide plate to make it easier for the printed material web to slide over the turner bar.
