ABSTRACT:
There is disclosed a process for the transfer of fiber material from one circuit of circulating liquid to another, where the fiber material is transported by circuits positioned at right angles to the axis of rotation of a rotary transfer or feed valve and the circulating, transporting liquids are screened off through self-cleaning screens. The transfer valve contains a pocket and three working positions, a filling circuit, an emptying circuit, and an intermediate position for preheating the fiber material or providing a temperature lock depending upon the rotation of the pocket.
