Abstract
A continuous washing machine has an impregnation bath and a rinsing chamber. The rinsing chamber includes three successive sieve drums over which the tubular fabric is made to pass. The fabric passes over the second downstream sieve drum in a reverse direction so as to overturn the fabric and expose the other surface thereof and to retain the fabric over the sieve drum. A sump area is maintained in the bottom of the chamber, and the liquors from the sump are recirculated by means of spray pipes spraying rinse liquor onto the fabric. The spent rinse liquor coming from the fabric over the first sieve drum is drained out of the chamber.
Claims5
An apparatus for treating tubular fabric, including a liquid treatment impregnation bath, means for passing the fabric through said bath, squeeze rollers for removing excess treating liquid from the fabric as it exits from the treatment bath, a first sieve drum, roller means for passing the tubular fabric over the first sieve drum, spray means for spraying rinse liquid onto the fabric as it passes over the first sieve drum, a second sieve drum downstream of the first sieve drum, means for passing the fabric above the second sieve drum and returning it in the opposite direction over and in contact with the second sieve drum such that the fabric has been reversed to expose the other surface thereof, spray means for spraying rinsing liquid onto the fabric as it passes over the second sieve drum, means for passing the fabric underneath the second sieve drum, and means for removing the excess rinsing liquor from the fabric.
