Abstract
In a godet for advancing and guiding an advancing synthetic filament yarn, the bearing housing for supporting a shaft consists of an inner bearing support and an outer cooling body, which are in a heat conducting contact with each other. Cooling of a bearing within the bearing support is enhanced because the material of the cooling body has a coefficient of thermal conduction which is greater than the coefficient of thermal conduction of the bearing support material. In a heated godet, a cup-shaped godet casing fits over the end of the shaft, and a stationary hollow cylindrical support is fit over the shaft within the godet casing. An annular space is defined between the support and the shaft, and a heating element is mounted to the circumference of the support. The bearing housing at least partially defines openings that provide cooling air to the annular space.
