Abstract
An apparatus for washing and scouring fabrics by means of a washing liquid, comprising a tub filled with washing liquid and a cylinder rotatable inside the tube and forming the driving means for the fabric. The latter, passing in the space between the cylinder and the bottom of the tub, is subjected to opposite jets of washing liquid impulsively emitted by opposite pairs of ejectors, whereby a continuous motion of the fabric is caused to take place and the washing liquid is continuously vibrating.
