Abstract: An apparatus for dyeing a fabric material comprising a semicircular dye vessel having at opposite ends upwardly directed openings, a first conduit and second conduit connected at one end to the respective openings of the vessel, a dye feed box with a jet nozzle and a deflecting means operatively associated with the jet nozzle. The fabric material is a narrow strip of tape bonded at both ends to form a loop. The deflecting means is rotatable in the first conduit for deflecting the flow of fabric material and dye liquid at an angle of approximately 45.degree. with respect to the vertical axis of the first conduit, the fabric material being oriented to form a succession of loops deposited one upon another and extending substantially radially of the vertical axis.

Abstract: A perforated beam apparatus is disclosed for dyeing or otherwise treating fabric materials, the apparatus comprising a horizontally disposed treatment vessel and a perforated cylindrical beam mounted concentrically in the vessel, and adapted to wind thereon layers of cloth, tapes, yarns and the like. There are established a main suction stream and a sub-suction stream of treating liquor, both streams flowing from a treatment chamber and merging into a heat exchange chamber. A pressure reserve tank is mounted above the treatment vessel for regulating the pressure therein and taking up air bubbles entrained with the flow of treatment liquor.
