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.
Claims9
A method of gathering coated reinforcing cord from a fabric constituted of longitudinally running warp cords numbering in a range of approximately 6 to 30 per inch and laterally running picks numbering in a range of approximately 2 to 6 per inch and interlaced with said warp cords, said method comprising treating said fabric as a unit with a liquid whereby said warp cords and picks are coated with said liquid and dried, and then advancing the treated fabric under tension lengthwise of said warp cords, tearing said picks into substantially equal lengths while advancing said fabric to divide the latter into a plurality of tapes each having a lesser number of warp cords than said fabric and picks of reduced length, winding said tapes into respective tape packages, unwinding each of said tape packages individually while advancing the components warp cords thereof lengthwise under tension, dislodging said picks from each of said tapes while advancing the latter, and winding said warp cords freed from said picks into respective packages.
