Abstract
A low-loss, high-energy efficiency and low-cost heatable godet has a plurality of short wavelength infrared radiation heaters closely juxtaposed with the inner wall of the hollow drum of a godet onto which a synthetic yarn can be fed. The heaters can be angularly equispaced within the interior of the drum, closely juxtaposed therewith and of different lengths to heat different axial zones of the drum differently. The heaters can be coated with a reflective material on their sides turned away from the drum to avoid scattering losses and to direct energy to the drum.
