ABSTRACT OF THE DISCLOSURE The invention covers a method and apparatus for sub- jecting a knitted tubular fabric to a dry high temperature in order to reorient the knitted stitch geometry of the fabric while maintaining a predetermined width of the fab- ric under a controlled longitudinal tension condition and allowing the fabric to set while maintaining the controlled longitudinal tension condition. The method involves moving a knitted tubualar fabric over a spreader to spread the fabric into a flattened tubular form of a predeter- mined width while at the same time imparting a lateral tension to the fabric. The inside edges of the form are engaged by a first edge drive to move the form over the spreader towards an edge drive transfer station while maintaining the predetermined width. At that station, the first drive is replaced by a second edge drive while still maintaining the predetermined width. The speed of the first drive is regulated with respect to the second drive in order to control longitudinal tension in the form while engaged by the second drive. The form is then moved by the second drive through a dry heat treat- ing station while maintaining the predetermined width and tension to alter the knitted stitch geometry and remove lateral tension therefrom. The fabric is then removed and allowed to cool and set while engaged by the second drive.
