In this method, an annular core is held by a core rotating means. Then a reel wound with a wire is revolved in one direction through the inside and the outside of the core by a reel revolving means by holding the reel wound with a wire alternately on one side and on the other side of the core. And a wire is wound helically around the core as the core is rotated in a circumferential direction in association with the revolving motion of the reel. ## Claims ### Claim 1 A method for manufacturing a cable bead, comprising the steps of: revolving a reel wound with a wire in one direction through the inside and the outside of an annular core by holding the reel alternately on one side and on the other side of the core; rotating the core in a circumferential direction in association with the revolving motion of the reel; and winding the wire helically around the core. ### Claim 2 (depends on 1) The method for manufacturing a cable bead according to claim 1, wherein the operation to be repeated comprises the steps of: holding the reel on a side thereof opposite from the core and swinging the reel on the other side of the core; switching the side for holding the reel after the swing motion; swinging the reel held from the switched side for holding the reel on the one side of the core; and again switching the side for holding the reel after the swing motion. ### Claim 3 (depends on 1) The method for manufacturing a cable bead according to claim 1, further comprising the steps of sliding the core, as it is rotated in a circumferential direction, in a direction from the outermost position toward the innermost position of the reel when the reel is swung from the inside to the outside of the core and sliding the core, as it is rotated in a circumferential direction, in a direction from the innermost position toward the outermost position of the reel when the reel is swung from the outside to the inside of the core. ### Claim 4 (depends on 1) The method for manufacturing a cable bead according to claim 1, wherein the reel is revolved within a plane perpendicular to a plane formed by the ring of the core. ### Claim 5 An apparatus for manufacturing a cable bead, comprising: a reel revolving means disposed on one side and on the other side of an annular core for revolving a reel wound with a wire through the inside and the outside of the core by holding the reel alternately on one side and on the other side of the core; and a core rotating means for rotating the core in a circumferential direction in association with the revolving motion of the reel, whereby the wire is wound helically around the core. ### Claim 6 (depends on 5) The apparatus for manufacturing a cable bead according to claim 5, wherein the reel revolving means further includes a first arm disposed on one side of the core to hold the reel on a side thereof opposite from the core and swing the reel to the other side of the core and a second arm disposed on the other side of the core to hold the reel on a side thereof opposite from the core and swing the reel to the one side of the core, each of the arms including a body, a first movable member rotatably connected to a body, a second movable member rotatably connected to the first movable member, and a holding member rotatably connected to the second movable member to hold the reel, the holding member provided with a switching means for holding and releasing the reel. ### Claim 7 (depends on 5) The apparatus for manufacturing a cable bead according to claim 5, further comprising a slide mechanism for sliding the core in a direction parallel to a straight line connecting a point where the reel is located at an innermost position of the core and a point where the reel is located at an outermost position of the core. ### Claim 8 (depends on 2) The method for manufacturing a cable bead according to claim 2, further comprising the steps of sliding the core, as it is rotated in a circumferential direction, in a direction from the outermost position toward the innermost position of the reel when the reel is swung from the inside to the outside of the core and sliding the core, as it is rotated in a circumferential direction, in a direction from the innermost position toward the outermost position of the reel when the reel is swung from the outside to the inside of the core. ### Claim 9 (depends on 2) The method for manufacturing a cable bead according to claim 2, wherein the reel is revolved within a plane perpendicular to a plane formed by the ring of the core. ### Claim 10 (depends on 3) The method for manufacturing a cable bead according to claim 3, wherein the reel is revolved within a plane perpendicular to a plane formed by the ring of the core. ### Claim 11 (depends on 8) The method for manufacturing a cable bead according to claim 8, wherein the reel is revolved within a plane perpendicular to a plane formed by the ring of the core. ### Claim 12 (depends on 6) The apparatus for manufacturing a cable bead according to claim 6, further comprising a slide mechanism for sliding the core in a direction parallel to a straight line connecting a point where the reel is located at an innermost position of the core and a point where the reel is located at an outermost position of the core.
