Abstract
The length of material, provided uniformly over the operating width with a liquid mixed with frothing chemicals, is to be massaged on the pile side for producing the froth and/or for the complete wetting of all pile fibers. A reel or a similar device exhibiting round bars uniformly distributed over its circumference and partially encompassed by the material serves for this purpose. The length of material is in contact under tension with the rotating reel. On the rear side, the material is urged against the reel by means of an air-impermeable hugger belt, held under tension, or by means of a wearproof pressure shell.

An apparatus for foam dyeing of lengths of textile material having pile fibers on a pile side thereof, comprising a dye liquor applicator for applying a foamable liquid-dye liquor to the pile side of said textile material, a stroking means arranged after the dye liquor applicator along a travel path of said textile material for alternately compressing and releasing the dye-containing pile fibers to cause the dye to foam on the pile fibers, said stroking means being arranged to directly contact the pile side of the textile material and being driven to rotate and to provide a relative motion between said textile material and said stroking means and means for conveying the textile material along said travel path in contact with said stroking means so that the stroking means is partially encompassed by said textile material.
