Abstract (en)
[origin: EP0354415A2] In the air cushion roller (1), air streams fed through a hollow space (12) in the interior of the roller emerge from openings in the roller jacket (8), by means of which air streams the sheets are pressed away from the roller jacket (8). For reducing the air stream noise, a noise-absorbing layer (18) is provided in the hollow space (12) with radial channels (19), which forms in the hollow space (12) an air-permeable partition wall equidistant from the roller jacket (8).
