ABSTRACT:
An apparatus for extracting a liquid from cloth in rope form including a rotary roller having a V- or U-shaped groove for guiding cloth in rope form, and a fixed hollow shaft or cylinder for rotatably supporting said rotary roller thereon. The rotary roller is provided with a number of small apertures radially extending through and distributed over the entire bottom of the groove, while the hollow shaft or cylinder has an opening at a position on the circumference thereof opposed to the small apertures of the rotary roller. The hollow shaft or cylinder is connected to a vaccum pump so that a vacuum suction force directed towards the axis of the rotary roller may be exerted on cloth in the groove through the opening and apertures.
