<p>The present invention relates to a composite ring tube (100) for ring spinning machines. The composite ring tube comprises a cylindrical tube having a top end (110) and a bottom end (130). The outer diameter of top end of composite ring tube is less than the outer diameter of bottom end of the composite ring tube providing a tapered structure to the cylindrical tube. The bottom end of the cylindrical tube is reinforced with plurality of layers of prepreg for firmly fitting the ring tube into the spindles of ring spinning machine to allow high speed operation. The decreased weight of the ring tube is leads to increased productivity while saving energy.</p> |
