Abstract
An improved apparatus for the continuous treatment of webs of materials such as textile materials with a foamed treatment medium. The apparatus includes a rotating cylinder, the length of which is at least equal to the width of material being treated and the circumference of which engages the web over a portion of the cylinder. The web is looped over the cylinder in a looping region and the apparatus further includes a foam feeding device which transfers foam to the web in a transfer region at the circumference of the cylinder. The improvement of the invention comprises a foam feeding means which includes a foam chamber disposed adjacent the cylinder at the looping region, the looping region being located at a side of the cylinder which descends during rotation of the cylinder. The foam chamber opens adjacent the web at the looping region and a wiper is disposed at the lower end of the foam chamber parallel to the longitudinal axis of the cylinder.
