Abstract
This disclosure teaches a method of longitudinally compressively shrinking a textile fabric web with the method comprising known steps of preconditioning the web, continuously feeding the web between a thick elastomeric belt and a heated polished cylinder having a low frictional resistance and thereafter drying the web. The method of this invention is characterized by selectively varying tension of the belt as well as selectively manually varying contact pressure between the belt and the polished cylinder. According to this invention skipping at high speeds is avoided and there is control of the pressure of the belt on the cylinder over a greater arc than by prior art methods.
