  • Patent number: 4150948
    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.
    Type: Grant

  • Patent number: 4085484
    Abstract: In the present invention, there is provided a pair of pressure rollers mounted on a frame for removing the excess liquid from the fabric at the nip formed between the rollers. A predetermined planar path passes through the nip of the rollers coincidental with the path of the tubular fabric, and a blade having a first flat elongated surface extends laterally of the path upstream of the squeeze rollers below and adjacent the path of the tubular fabric such that the tubular fabric is in contact with the surface. A second surface upstream of the first surface merges therewith and at an angle sloping downwardly from the first surface. A third surface downstream of the first surface merges therewith and is at an angle to the plane passing through the path of the fabric, such that the blade causes liquid and air to be drained from the tubular fabric as it passes over the first surface in contact therewith at relatively high speeds.
