Abstract (en)
[origin: US4552778A] A viscous medium such as a fabric treatment foam is applied to a fabric web by a distributing device extending across the continuously moving web. The foam is pressurized in a first stage and delivered over a long pipe to a distributing chamber of the device where it is distributed over the entire width of the web. The foam is then admitted into a compartment in which it can form a column surmounted by a float to establish a lower second pressure stage and at this lower pressure the foam passes to a pressure generator which forces the foam from a slot-like orifice at a third pressure higher than the second pressure.
