Abstract
This disclosure teaches an apparatus for longitudinally compressively shrinking a textile fabric web by continuously feeding the web between a thick elastomeric belt and a heated polished cylinder having a low frictional resistance. The apparatus 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 pressure of the belt on the cylinder over a greater arc than by prior art apparatus.
