Devices for carrying out this process are described.
Claims3
In a process for the uniform drying of a travelling moist textile material in the form of a structured fiber web impregnated with a fluid treating agent, containing a solid material that remains permanently in the web after drying, said process being of the type in which either one or both sides of the web are exposed to a heat source selected from a stream of hot air and radiant heat as the web passes over a bank of rotating rolls, the improvement which comprises applying the heat from said heat source to the moving web in a transversely oscillatory manner to improve the uniformity of drying across the width of the web.
