Abstract: Method and apparatus for liquid treatment of a lengthy woven or knitted cloth band of an endless form for scouring, dyeing and desizing of cloths. A cloth band is helically wound on plurality of cylindrical drums disposed axially in longitudinal arrangement with helical parts thereof depending from the cylindrical drums. Rotation of the cylindrical drums at progressively reduced peripheral speeds causes the helical parts of the cloth to depend at uniform lengths from the drums and thereafter all cylindrical durms are rotated at an equal speed.
