Abstract
A liquid applicator for a wide length of material, operating according to the overflow principle, has a construction which ensures uniform dye application over the operating width. This applicator now makes it possible to effect quick color change, because the capacity of the applicator is smaller than 5 l/m and, by a special arrangement of liquid-distributing chambers in the applicator, a uniform liquid film exhibiting laminar flow is ensured.
