Spiral apparatus for the fluid treatment of fabrics in roped form
Abstract
Abstract 1,088,665. Treating fabric. BRITISH SILK DYEING CO. Ltd. Jan. 25, 1965 [Jan. 24, 1964], No. 3086/64. Heading D1L. A method of treating, e.g. scouring, bleaching, or dyeing fabrics in rope form 5 comprises a winch roller 12, preferably of elliptical crosssection, an advancing guide 13, (e.g. a deep threaded screw) arranged to be rotated over a bath 10 of the treatment fluid and a winding- on device consisting of an endless conveyer 14 (e.g. an endless chain) having a finger 18 carrying an eye hook or clamp to which one end 5A of the fabric-rope is attached to be continuously wound onto one end of the roller 12 and guide 13. The roller 12 and guide 13 rotate in direction A so as to cause the convolutions thereon to move in direction B away from the winding on conveyer 14. At the start of a treatment a batch of material is placed in the bath, one end is attached to the finger 18 and the device started up. As a convolution is wound on the end of the roller 12 and guide 13 it is moved away therefrom by the advancing action of guide 13. This continues until all the fabric is wound onto the roller and guide and only a short trailing end SC remains. The device then continues to run with the convolutions remaining axially stationary until the treatment is completed. The tank 10 may be closed and maintained at elevated temperatures and/or pressure. The conveyer 14 and guide 13 may be driven from the roller 12 via a variable speed gearbox by adjustment of which the length of material in a convolution may be adjusted. In place of the helical guide 13 a comb device which is intermittently moved to one side and then returned to its starting point may be used.
