Abstract
Method and apparatus for liquid treatment of a lengthy woven or knitted cloth band of an endless form for scouring, dyeing and desizing of cloths. A cloth band is helically wound on plurality of cylindrical drums disposed axially in longitudinal arrangement with helical parts thereof depending from the cylindrical drums. Rotation of the cylindrical drums at progressively reduced peripheral speeds causes the helical parts of the cloth to depend at uniform lengths from the drums and thereafter all cylindrical durms are rotated at an equal speed.
Claims2
An apparatus for liquid treatment of a lengthy woven or knitted cloth band for scouring, dyeing and desizing of cloths, comprising a plurality of drums rotatably mounted on a common shaft about which drums said cloth band is helically wound, a treating tub beneath said drums for said treatment, means for rotating said drums at progressively reduced peripheral speeds from one end to the other in order to depend each helical part of the cloth band downwardly from the drums at a uniform length and means for rotating drums at an equal speed thereby circulating the cloth band through the treating liquid in said tub to apply the desired treatment, said means for rotating the drums at an equal speed having a relationship with the means for rotating the drums such that the equal speed takes place after the results of the reduced peripheral speeds are achieved.
An apparatus for liquid treatment of a lengthy woven or knitted cloth band for scouring, dyeing and desizing of cloths, comprising a number of drums of a same diameter mounted and arranged adjacent to each other on a common shaft, means for rotating said drums successively at lower speeds in the order of sequence from a first drum to a last drum and also means for rotating all drums in the same direction at the same speed, the latter means being provided with a drive shaft in parallel with the shaft mounting said number of drums, said drive shaft being provided with driving sprocket wheels of the same diameter, said driving sprocket wheels transmitting power to rotary sprocket wheels on said shaft with said first drum fixed directly on said shaft and said first drum is rotatable with said shaft, an internal drum being rotatably mounted on said shaft with the second drum secured to the internal drum to make an adjacent drum to succeed said first drum to rotate, said internal drum having a rotary sprocket wheel larger in diameter than the rotary sprocket wheel rotating said first drum, said rotary sprocket wheel having power transmitted thereto from a separate driving sprocket wheel having a free wheel and mounted on a drive shaft, transmission means or a clutch meshing with a pawl on the rotary sprocket wheel for the internal drum, and a treating tub placed beneath the drums for dyeing treatment, wherein the lengthy cloth band depends helically from the drums with each drooping portion in the tub as the drums are rotated in the same direction at progressively reduced speeds from the first part to the last one so that loosened portions of the lengthy cloth band may form a uniform length when the band cloth is placed in the tub as the drums are rotated in the same direction and same speed.
