Abstract

A method for depositing high-speed yarns by means of withdrawal nozzles actuated by means of a gaseous propellant, characterized in that the yarns, after passing the withdrawal nozzles, are subjected to dispersion and, by means of, at least, a part of the propellant stream flows, between the outlet of the withdrawal nozzle acceleration zone and the dispersion, a longer guide channel, such that the speed of the propellant stream in this channel always be greater than the thread speed.
