An apparatus for wet treating webs of textile material in which the web is passed over and below staggered rollers in a trough adapted to receive treating liquid into which at least some rollers are at least partially immersed while the web material leaving the last roller is wound onto a perforated drum which latter is, relatively to said last roller, pressed against the latter at a substantially uniform pressure during the winding-up operation, said drum being arranged in a housing adapted selectively to be closed completely for independent wet treatment of material on the perforated drum.
