Abstract
A suction roller system includes a suction roller and a control head having a ventilation zone situated at a face side of the suction roller. The suction roller system allows rapid ventilation of the suction bores situated on the face side opposite the control head via a cost-advantageous and space-saving expansion. For this purpose, the suction roller is equipped, on the second face side, with a closure plate having an opening that corresponds to the ventilation zone.
