Abstract (en)

[origin: EP0472050A2] In a liquid-application unit operating according to the refilling principle, the liquid which is to be fed via hoses is to be distributed uniformly over the working width. This took place previously by means of a reservoir space which is advantageously formed from a conically increasing retaining space, out of which the liquid runs onto the material web via an overflow edge and a guide surface. However, it is also essential with this low-volume liquid retaining space that the liquid be supplied uniformly over the working width, in particular when changing colour. In order to achieve this, individual liquid distribution spaces which extend one directly next to the other over the working width are defined in which uniformity is achieved by means of a forced distribution of the liquid from a feed opening to a number of outflow openings. This forced distribution takes place similarly to the structure of a family tree, namely in steps from one opening to two, four, eight, sixteen outflow openings and so on. <IMAGE>
