Abstract

A NOZZLE BOX HAVING NEGATIVE PRESSURE NOZZLES FOR TREATMENT OF MOBILE MATERIAL WEBS An arrangement of nozzles with negative pressure intended for contact-free treatment of mobile material webs (W), comprises a nozzle box provided with a foil face (16; 16, 16T) placed facing the web (W), in connection with which face there are two nozzle slots (17, 18). The nozzle box (10) has a planar carrier face (16), at one of whose edges there is a curved Coanda air-guide face (16R), in connection with which there is the first nozzle (17), at which the initial direction (S0) of its blowing is perpendicular to the plane of the web (W). The Coanda air-guide face (16R) turns the air blow (v1) that comes from the first nozzle (17) towards the direction of the carrier face (16) and of the plane of the web (W) running over the carrier face. In the lateral area of the planar carrier face (16) opposite in relation to the first nozzle (17), there is a substantially planar guide face (16) or guide wing (16T), which extends said planar carrier face (16) continuously. The guide face (16a) is parallel to the plane of the carrier face (16) or, when a guide wing (16T) is used, starting from the plane (16) of the carrier face, to some extent inclined (angle a) towards the web (W). In connection with, or at the proximity of, the outer edge (20) of said guide face (16a) or guide wing (16T) there is a second blow nozzle (18), whose direction (v2) is parallel to the guide wing (16T) of the guide face (16a).
