ABSTRACT:
An elongated knit web is flattened and guided by an apparatus having a support frame which extends longitudinally in a plane and which has an upstream and a downstream end. A pivot supports this frame for pivoting about a pivot axis transverse to the plane at the upstream end. A pair of transversely extending and longitudinally spaced spreader rollers are provided on the frame adjacent the upstream end and each has a pair of screwthread formations of opposite hand, these spreader rollers being driven to spread out the web transversely. A pair of transversely extending and longitudinally spaced guide rollers are provided on the frame between the spreader rollers and the downstream end, these guide rollers being freely rotating and having surfaces which are made to adhere to the web to prevent its edges from curling up. A control system pivots the frame about its pivot axis to position the edges of the exiting web.
