Abstract
Thin articles such as letters are conveyed over a supporting fluid layer formed against a track surface along which they move. This layer is built up by jets issuing from nozzles located on both sides of the track surface and opening flush with the latter. The nozzles are oriented towards the center line of the track with somme inclination in the direction of motion of the articles, in order that the velocity of the jets presents a longitudinal component parallel to this direction and a transverse component pointing towards the center of the track.
