The upper and lower parts of the pneumatic sheet guide device are firmly connected to one another and form a hollow space. The upper (20) and the lower (22) parts are of a flexible material, the flexibility of the lower part being greater than that of the upper part. The upper part is of steel plate. The lower part is of an elastomer, a foil or a textile material. The upper part (20) and the lower part (22) at the edge zones are firmly and air-impermeably connected to one another. The connection between the two parts is by rivets and holding platelets. |
