The application is directed principally to a method of processing open width fabrics, particularly distortable fabrics such as those of knitted construction, in a rotary-type of tenter processor in which the fabric is acted upon by high velocity air streams. The fabric is first engaged by its opposed edge extremities and distended to a predetermined width; it remains so engaged throughout the processing operation. The thus engaged fabric is supplied to and mechanically supported by a synchronously rotating processing drum. Of significance, the fabric, regardless of its width, is applied symmetrically to the center area of the drum and held by its edges at a uniform width regardless of the overall axial length of the drum, which may be considerably greater than the width of a given fabric web. While the fabric is supported on the drum, high velocity streams, extending over the full axial length of the drum and independent of the width of the fabric, are directed radially through the fabric and drum to effect the desired processing. Exceptional uniformity of processing results is thus achieved.
