ABSTRACT:
Tubular knitted fabric is circularly spread and simultaneously squeezed for removing treatment liquor. Spreader components are separated from squeezing components in order to relieve the spreader components from the squeezing forces. For this purpose, pairs (23) of squeezer rollers (23A, 23B) are mounted on brackets (24, 25) which are rigidly secured to the outer pipe section (19A) of the central carrier column (19). The brackets (24, 25) are so arranged that they do not interfere with the spaced struts or braces (20, 21) of the spreader rollers (12). Each pair of squeezer rollers (23) cooperates with a revolving single squeeze roller (26) that is radially adjustable by a power drive such as a piston cylinder device (27) relative to the central column (19) to thereby adjust the squeezing gap between the pair of squeezer rollers and the single squeeze roller and thus also the squeezing force. The adjustment of the squeezing gap also determines the squeezing forces, whereby the arrangement is such that squeezing force components exerted by neighboring squeezer units support each other directly.
