Abstract
A godet for advancing, guiding, and heating an advancing synthetic filament yarn, which includes a rotating godet casing, which is cup shaped and is mounted over a stationary, tubular support. In the space formed between the godet casing and the support, a radiation heater is arranged on the circumference of the support, and the radiation heater is formed by a heating coil which is wound about the support with a plurality of windings. The coil has over its length different spacings between adjacent windings to provide non-uniform heating along the length of the casing and thereby compensate for the non-uniform cooling of the casing which naturally occurs.
