Abstract
Abstract An apparatus for the heat treatment of textile material comprises a plurality of nozzle boxes extending across the operating width at least on one side of the length of material. The nozzle boxes are fed from a front face and have openings discharging in a direction towards the length of material and a fan is disposed at the feed end of these nozzle boxes. The fan is a radial flow fan. It is arranged with its axis of rotation at right angles to the plane of the length of material on the long side of the apparatus.
