ABSTRACT:
An adjustable yarn tensioning device for maintaining generally uniform tension in a running textile yarn that runs through a ball seat so that a ball on the seat applies a gravitational tensioning force to the running yarn. The ball seat is formed in a depending cup that is selectively rotated to align with any one of a plurality of chambers through which the yarn travels to a common outlet. The chambers contain different size or weight ball combinations so that alignments can be selected to provide a desired tension. In addition to a preferred embodiment in which the cup rotates under the chambers, the device may be formed for sliding of the cup longitudinally under a straight line arrangement of the chambers.
