ABSTRACT:
An apparatus for forming foam including a rotatable screw shaft having concave grooves or convex stripes extending spirally along its outer circumference and located in a cylinder closely spaced from one another for passing a treating solution containing a foaming agent, such as soap, together with pressurized air through the gap between the screw shaft and the cylinder. It is preferable to provide a plurality of square grooves along the inner circumference of the cylinder extending spirally or in the axial direction of the cylinder. Foam of the treating solution can be continuously produced in an effective manner, and the apparatus is particularly suitable for continuously applying a treating solution to a cloth.
