1,151,138. Pressure treatment for continuous length sheet material. WAKAYAMA IRON WORKS Ltd. and HAMANO SENI KOGYO K.K. 9 Dec., 1966 [20 Dec., 1965], No. 55309/66. Heading D1L. An apparatus for the sub- or super-atmospheric treatment of continuous length sheet like material has a liquid seal 4 at the inlet for the material and the material is hermetically clasped between a pair of moving endless bands 1 and 1' as it passes through the liquid, the bands passing over return rollers 3" immediately adjacent the material outlet side of the liquid seal so that the bands barely pass into the treatment zone 5. The liquid of the seal is a low fused molten metal. The hermetic sealing effect between the belts 1 and the material 2 is enhanced by installing air suction means between the belts immediately before they are brought into adherence by rollers 3'. The perimetric edges of the bands may be composed of magnetic rubber, or alternatively co-operating grooves and ridges may be provided on the bands 1 and 1'. The bands are made of a material which can withstand the molten metal, e.g. rubber or synthetic resins. The outlet of the treatment zone 5 can be provided with a similar sealing arrangement, or alternatively the same liquid seal can act as inlet and outlet for the material (Fig. 3, not shown). Where the apparatus is concerned with dyeing a dye bath 8 may be arranged externally (Fig. 1) or internally of the apparatus. A single batch or double batch roller can be provided within the treatment chamber (Fig. 5). The sheet can be reciprocatively treated by winding and unwinding means disposed externally of the apparatus. |
