Abstract: A web of textile material which is to be permeated with a liquid is caused to move upwardly through the nip of two squeezing rolls which serve to expel air and/or moisture and are immediately adjacent a liquid bath. The freshly squeezed increments of the web act not unlike sponges and thus accept substantial quantities of liquid, and the surplus of liquid is expelled from the web by two rolls which are installed above the bath and define a nip of variable width. If necessary, the web can be contacted by a suitable wetting agent on its way toward the nip of the squeezing rolls.
