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.

Claims

1. A suction roller system comprising:

(a) a rotating suction roller having first and second face sides;

(b) a control head comprising a ventilation zone situated at the first face side of the suction roller; and

(c) a closure plate provided on the second face side of the suction roller, said closure plate having an opening corresponding to the ventilation zone.

2. The suction roller system according to claim 1, wherein the opening of the closure plate has a width that narrows counter to a direction of rotation of the suction roller.

3. The suction roller system according to claim 1, wherein the second face side of the suction roller corresponds to the closure plate and has a plurality of magnets.

4. The suction roller system according to claim 1, further comprising a ventilation chamber bordering on a side of the closure plate that faces away from the suction roller.
