Abstract
The disclosure is directed to apparatus for processing of tubular knitted fabric, including an internal flat spreader and width-adjustable edge drives, typically used in connection with other processing apparatus, such as calendars, padding equipment, compressive shrinking stations, etc. The apparatus utilizes a pre-loaded, resiliently biased spreader frame which, within its operating limits, presses outwardly against adjustably movable, opposed edge drive rolls. The spreader frame, which is positioned internally of the moving fabric tube during processing operations, is capable of in-process width adjustments, without either stopping the processing line or damaging the fabric. Width adjustment of the internal spreader frame may be accomplished from a remote operator station. Moreover, the apparatus may incorporate edge-sensing means operative automatically to adjust the width of the spreader to maintain uniformity of width in the processed fabric.
