A method and device for contact-free treatment of a web in which the web is treated, for example supported, reversed, spread, carried, and/or dried, by means of blowings which provide a carrier-face zone. The carrier-face zone has a curved form regulatable in a direction transverse to the direction of progress of the web. The nozzle-carrier face unit of the device is bent to the curved form in the cross direction of the machine while a frame part of the device is kept in a stationary position. The device includes a regulation arrangement for bending the nozzle-carrier- face unit to a curve form in the direction transverse to the running direction of the web while the frame part of the device is supported in a stationary position.
