Abstract: A spreader-propeller apparatus for processing of tubular knitted fabric. Each of two spaced-apart frame sections is formed of upper and lower sheet metal sections mounting a plurality of grooved guide rollers carrying fabric-engaging propeller belts. The frame structure supports entry-side and exit-side belts which, in the mid-regions of the frame structure, are trained about vertically extended substantially cylindrical driving rolls. Smooth surfaced, large diameter tubular structural elements are rigidly secured above and below the sheet metal frame sections and are transitionally contoured in bridging portions to extend at least slightly above and slightly below the vertically extending drive rollers. The geometry of the sheet metal frame sections and the smooth wall tubing secured thereto is such that tubular knitted fabric being processed on the spreader is at all times guided away from and held in spaced relation to fixed surfaces presenting an edge or corner.
