Abstract: The invention relates to a yarn handling arrangement in which the yarn is subjected to conditioning in a humid atmosphere before and as it is drawn off for use in a textile machine. The apparatus described in an example consists of an enclosure comprising a housing, in one compartment whereof are a plurality of pairs of bobbins on support rods, another compartment being defined by a sleeve member which is kept constantly moist by a water distributing device. A flow of air is arranged to fill the sleeve member and to escape therefrom through slots provided at levels corresponding to each of the levels at which the bobbins are supported.
