Abstract
A yarn package is supported on a horizontal spindle in a thread-supply apparatus and the thread is drawn horizontally away from the package. A flexible belt is hung from one end on a support rod displaceable toward and away from the spindle and extending parallel to the spindle. This belt is provided with a weight at its other end and is wrapped around the package completely with the weight hanging down past the support. This belt forms a thread-brake that ensures even tension in the filament being pulled from the package.
