Abstract
Method of continuously applying a foamed treatment medium to a planar textile structure which includes applying the foam directly to a planar follower guidable synchronously into areal contact with the planar textile structure, and transfering the foam from the planar follower into the planar textile structure by applying vacuum, and apparatus for carrying out the method.

Method of continuously applying a foamed treatment medium to a planar textile structure which comprises applying the foam directly to the surface of an air-impermeable planar follower, guiding the planar follower synchronously into areal contact with the planar textile structure, and transferring the foam from the surface of the planar follower into the planar textile structure while the planar follower and the planar textile structure are in areal contact by applying vacuum to a side of the planar textile structure opposite the air-impermeable planar follower.
Apparatus for performing a method of continuously applying a foamed treatment medium to a planar textile structure comprising a drum having, at the shell surface thereof, an evacuatable support layer, an air-impermeable planar follower spanning part of the drum periphery in areal contact with and for guiding the planar textile structure on the drum shell surface, said planar follower having an inlet section supported by at least one roller, means disposed at said inlet section for supplying foam to be applied between said planar textile structure and said planar follower, a wiper disposed opposite said one roller for uniformly distributing foamed treatment applied to the planar follower region preceding said wiper means for supplying suction through said support layer to a side of the planar textile structure opposite said air-impermeable planar follower, and means for separating the planar textile structure and the planar follower from one another.
