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.

Dependent claims

An apparatus for simultaneously spreading and squeezing tubular knit fabric, comprising a plurality of squeezer units (13), each squeezer unit comprising a squeezer roller pair (23A, 23B) rotatably mounted in stationary brackets (24, 25) secured to an outer pipe section (19A) of a central spreader carrier column (19) having a central longitudinal axis so that the squeezer roller pairs are separated from braces or struts (20, 21) of said central spreader carrier column (19), a single squeeze roller (26) cooperating with each squeezer roller pair (23A, 23B), a first power drive (32) for rotating said roller pair (23) about the single squeeze roller (26), a second power drive (27) for radially adjusting said squeeze roller (26) toward and away from the respective squeezer roller pair (23) for varying the squeezing force (F), a third power drive for revolving said single squeeze roller (26) and its respective second power drive (27) around said central column (19), a pair of mounting rings (28) for revolvingly supporting said squeeze roller (26) and its respective second power drive (27), and wherein said pair of rollers (23) and said single squeeze roller (26) are mounted with their rotational axes passing through the corners of a triangle so that squeeze force components applied by said second power drives (27) oppose each other, whereby loads are substantially reduced.
