Abstract
Nozzle apparatus of the over-pressure type for handling web material includes a nozzle box having a nozzle carrying surface which is curved towards the interior of the box to define a recess in the direction of web run and a pair of opposed nozzle slots located so that gas jets issuing therefrom follow the nozzle carrying surface in opposite directions with respect to each other so as to meet in the region of the curved recess to form a tranquilization zone. In this manner an air cushion is formed for the web which extends over a considerable distance in the direction of the web run to carry the web.
