Abstract
A method and apparatus for separating and winding pre-treated yarn, for example, tire cord, the method comprising two stages. In a first stage, a coated and heat-set fabric, constituted of longitudinally running warp cords and laterally running picks interlaced with the warp cords, is subdivided into a plurality of elongate tapes, each tape having a lesser number of warp cords than the fabric and picks of reduced linear extent. The tapes are then wound into respective packages. In the second stage, the tapes are unwound and divided each into a plurality of independent warp cords free from the picks. The warp cords are then wound into respective packages.
