Abstract
Abstract A device for continuously treating fabrics which comprises an outer shell body, a perforated inner vessel of a half-cut drum shape provided within said outer shell body and pivotally supported on rollers and driven by a shaft to be swingably oscillated therewithin, and a pair of fabric inlet and outlet tubes provided at each end of said inner vessel, respectively, in alignment with an axial line thereof; and, said inner vessel being provided with one or more turbulence plates whose height and shape are changeable disposed on its inside wall in an axial direction thereof, a pair of plates having a suitable width to prevent a fabric material from jumping out thereof under treating conditions fixed to each longitudinal edge thereof covering its whole length, respectively, and a plurality of parallel grooves having a saw-tooth cross-section on its entire inside surface which are extending to both sides of its axial line at an angle with respect thereto.

Claim 3
Independent Claim
147 words
A device for continuously treating fabrics which comprises an outer shell body, a perforated inner vessel of a half-cut drum shape provided within said outer shell body and pivotally supported by a shaft to be swingably oscillated therewithin, a pair of fabric inlet and outlet tubes provided at each end of said inner vessel, respectively, in alignment with an axial line thereof, and a recycling pump means for sucking in a treating liquid contained in said outer shell body and jetting the liquid into said fabric inlet tube, said inner vessel being provided with one or more turbulence plates whose height and shape are changeable disposed on its inside wall in an axial direction thereof and a pair of plates having a suitable width to prevent a fabric material from jumping out thereof under treating conditions fixed to each longitudinal edge thereof covering its whole length, respectively.
