Method and apparatus for manufacturing steel card

Abstract

The present invention relates to a method and an apparatus for manufacturing a steel cord. A method according to the present invention comprises the steps of: combining a plurality of the steel filaments supplied from the bobbin by means of the guide rollers; applying a twist pattern to the combined filaments by rotating a pair of flyers arranged between a pair of turn rollers in the counterclockwise direction, and advancing them; applying a further twist pattern to the advanced cord by rotating another pair of flyers arranged between another pair of turn rollers in the reverse direction; stabilizing the cord by means of the overtwist; and winding the resulted cord. The method and apparatus for manufacturing the steel cord have effects that productivity can be improved up to two times or six times even with the same revolution, as compared with the manufacturing apparatus of the prior art.
