An air cushion nozzle for a device for conveying a web in suspension on an air cushion comprising a housing with two opposed walls having bent legs at the ends thereof resting on respective baffle plate portions supported on the housing. The legs have spaced semi-circular recesses therein forming tongues between the recesses which are in contact with the baffle plate portions to form two rows of discharge outlets for jets of air at the recesses extending toward one another in parallel to form the air cushion. The baffle plate portions can be joined together by a perforate plate. The baffle plate means can be bent at different angles to produce different angles of inclination for the jets of air produced at the two rows of discharge outlets.
