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.
