Abstract

The object of the present invention is the free retraction of thread spirals placed on a perforated conveyor belt during a heat treatment such as heat retraction or heat fixing of dyes. The device applies shaking movements or vibrations to a vertical component of the perforated belt, especially inside a heat treatment enclosure. It consists of an oscillating rotatable shaft transversely disposed inside the enclosure and applied to the lower surface of the belt. The shaft may have one or more plane surfaces, for example a rectangular transverse section.
