<p>A running fabric web is fed in flat tubular or openwidth form by means of an openwork conveyor belt below a battery of spray bars which apply a liquid such as a scouring solvent onto the fabric. The spray bars are provided with arcuate baffles which convert a spray discharge into a continuous sheet of liquid which pours onto the web. Excess liquid is then removed by a suction box disposed under the belt. A pair of tapered curtains trails along the top of the belt on either side thereof to cover the suction box slot beyond the edges of the fabric which forces the suction action through the fabric. The curtains are wound on a reefing roller by which the curtains may be selectively extended or retracted according to the width of the fabric being processed. The fabric is then delivered through a drying chamber where the material is dried and the excess solvent is recovered.</p> |
