ABSTRACT:
The invention proposes an improved yarn winding arrangement including a series of bobbins and spindles. The arrangement includes a fluid operated yarn sucking and projecting unit positioned at a distance substantially above its related bobbin and in close proximity to the starting point of the yarn balloon formed directly above the bobbin. A first fluid operated, waste yarn sucker is operatively connected with the unit. A second fluid operated waste yarn sucker is positioned in proximity to the root end of the yarn for receiving the yarn projecting fluidically from the discharge end of the aforementioned unit. The unit includes a sleeve as its main body formed with a longitudinally extending slot for sucking therethrough the yarn for deviating it from its regular running course to a wasting one.
