Textile spindle

The jacket enclosing a motor driven textile spindle of the type wherein the spindle is driven by a separate motor which is mounted on a common base with the spindle is modified to include air inlet and air exit openings. The motor is located in proximity to the spindle and is coupled to it by a toothed belt or the like. As the spindle is rotated by the motor air is drawn in through the inlet opening of the spindle and exits through the exit openings in the form of a strong stream of air which blows on and cools the motor. In this manner the spindle doubles as a fan for the motor and the necessity of providing a separate fan for the motor is avoided, resulting in savings in space and energy for driving a fan.
