Abstract
Abstract In a textile yarn processing machine, such as a twister, spinning frame or the like, having a spindle assembly for the processing of yarn which includes a carrier mechanism having a carrier member for supporting thereon a hollow supply package of yarn to be processed and a hollow yarn entry tube carried within said carrier member and extending outwardly therefrom axially of the supply package supported thereon for receiving the yarn from the supply package and providing a passageway for the yarn therethrough for processing by the spindle assembly; the improvement of a yarn wetting mechanism carried by the carrier mechanism for applying a wetting agent to the yarn as it passes in its path of travel from the supply package for processing by the spindle assembly. The wetting mechanism includes a reservoir carrying a supply of wetting agent and a porous, firm, elongate, wetting member having absorbent and capillary qualities. One end of the wetting member is positioned within the reservoir and in contact with the wetting agent for absorbing the wetting agent and passing the wetting agent by capillary action to the other end of the wetting member which is positioned away from the reservoir and in the path of travel of the yarn from the supply package to the yarn entry tube. The other end of the wetting member is in the form of a solid of revolution for contact with the traveling yarn for applying the wetting agent thereto.
