A turner bar for a rotary press for deflecting a substrate web in two web running directions is acted upon by pressurized air. The turner bar includes at least one inner tube and one outer tube, which have air discharge holes assigned to one another to produce an air cushion above the turner bar. The inner tube can be adjusted relative to the outer tube, so that the air discharge holes can be closed in such a way that the air cushion is adapted to the margins of the substrate web. It is thus possible to use the turner bar in both web running directions.
