Abstract
Abstract An apparatus for continuously applying a treating solution as foam to a cloth, comprising a U-shaped foam tank for storing foam of a treating solution such as a dye solution supplied from an apparatus for generating foam of the treating solution, guide rolls for transporting a cloth to be treated continuously through the foam tank so as to adhere the foam of the treating solution to the cloth while the cloth is passing through the foam tank, and a means for controlling the amount of foam adhered to the cloth in taking out the cloth from the foam tank. By using this apparatus, a necessary and sufficient amount of the treating solution for the subsequent heat treatment of the cloth can be applied to the cloth uniformly with no need of removing the excess of treating solution and/or solvent from the cloth prior to the heat treatment.

Claim 1
Independent Claim
140 words
An apparatus for continuously applying a treating solution as foam to a cloth, comprising a U-shaped foam tank for storing foam of a treating solution such as a dye solution, said U-shaped foam tank having a pair of upwardly extending legs and connected at the bottom of a bight section, an apparatus for generating foam of the treating solution connected to the bight section of said U-shaped foam tank, guide rolls for transporting a cloth to be treated continuously through the foam tank first downwardly through one of said legs and then upwardly through the other one of said legs so as to adhere the foam of the treating solution to the cloth while the cloth is passing therethrough, and a means for controlling the amount of foam adhered to the cloth in removing the cloth from the foam tank.
