Contact-free guiding and handling of continuous material web

摘要

The nozzle element producing the fluid flow, on its side of the fluid pressure chamber (1) facing the material web (2), is enclosed by a cover plate (3). This is curved in the path run direction (b) and forming the base surface (3a) for the fluid flow cushion (4). The cover has on the curvature vertex line (s), or in the region adjacent to this, several transverse slot nozzles (6) or rows of holes running parallel to the curvature vertex line.
