ABSTRACT:
In a tensioning device of the seated-ball type, an annular ball seating member is mounted in vertically adjustable spaced relationship to a tubular ball retaining member disposed thereabove and in axial alignment therewith. A ball element supported upon the seating member projects upwardly therefrom into the tubular member and is thereby restrained against excessive lateral movement during operation of the device, at which time the yarn undergoing tensioning passes upwardly through the seating member and then laterally therefrom through the space between the seating member and the overlying tubular member. The vertical adjustability of the seating member permits various changes to be made in the operating characteristics of the device, including variation of the degree of lateral constraint imposed upon the ball element.
