Abstract: A method is provided for winding an elastic yarn into a cylindrical substantially straight-ended yarn package. The method includes feeding an elastic or elastomeric yarn at a substantially constant speed to a tube core to form the yarn package. The yarn package is rotated such that the yarn package with a substantially constant surface speed. The yarn is wound to form layers of helical coils, while providing a helix angle variation of greater than zero up to +/- 80%.
