Abstract

Improvements in the devices for treatment of the width of fabrics by means of liquids, characterized in that they are constituted by a tub for the liquid, provided with supply and drainage ducts, inside which a horizontal and concentric three-cylinder device is housed, of stainless steel plate that covers the width of the fabric, in which the outer cylinder has a multitude of perforations and is equipped with a rotating movement, while the intermediate cylinder, also equipped with perforations, remains fixed and the inner cylinder offers a lobed contour and it is also equipped with a rotation movement capable of having a relative speed with respect to the outside, which ranges from a negative value to a positive value, including a null value, a continuous piece of tissue being properly applied to the outer cylinder contour. and guided by means of adjacent longitudinal rollers, the pertinent being arranged it is supporting and driving means for such cylinders and rollers, resulting that, when the outer and inner cylinders are in motion, and the assembly is submerged in an active liquid, through the intermediate cylinder successive actions of penetration and expulsion of the same liquid take place. they create cycloidal turbulences that, passing through the outer cylinder and the fabric applied in it, determine the treaty action of the latter.
