Abstract
In dye applicators that operate by the pouring principle, it is known to hold back liquid flowing over an overflow weir in a liquid supply chamber located upstream of the weir. To achieve a dye applicator that can be adjusted to a desired working width, this liquid supply chamber is subdivided several times by limiting walls, and a liquid inflow bore is associated with each of the partial liquid supply chambers thus formed. The flanks of the liquid supply chambers delimited by a parallel dam and opposite dam are designed to diverge and to create a plurality of separate liquid supply chambers that expands toward the overflow weir.

A device for applying a liquid film of considerable width, exhibiting laminar flow and uniformly thin over the working width of the device, to a continuously advancing web of goods, said device comprising a liquid supply chamber which is delimited on one side by a first dam directed diagonally upward from the horizontal and extending over the working width, said dam having an overflow weir in the flow direction of the liquid as well as a guiding surface abutting the overflow weir, from the lower edge of which surface a film of liquid overflows onto the web of goods, and which also is delimited by an opposite second dam at a distance from the first dam, with the liquid supply chamber defining a space having a liquid inflow area at the end opposite the overflow weir, said area being formed by a plurality of liquid inflow openings connected with at least one liquid feed line supplied with liquid, and said liquid supply chamber extending over the full working width of the entire device in the vicinity of the overflow weir being divided by at least one limiting wall in the space of liquid supply chamber, said at least one limiting wall extending from the overflow weir to the liquid inflow area to provide a plurality of partial liquid supply chambers extending across the full wording width.
