Abstract
A thread drawn upwardly from a stationary yarn package into the top of a hollow spindle, exiting from a payoff disk on that spindle below the yarn package and then rising along the inner wall of a balloon-limiting cylinder, is wetted by water entering the top of the cylinder through several peripherally spaced radial wall apertures or through an overhanging spout. An annular trough at the bottom of the cylinder intercepts excess water and returns it to a reservoir for recirculation to a supply channel.
