BALL SPLITTING METHOD FOR SPLITTING BALL PART FITTED ON CORD PART OF STRING MEMBER AND BALL SPLITTING TOOL
To relatively easily split different-pitch ball parts without damaging a cord part.SOLUTION: A cord part 12 formed in a string shape is connected by a connecting member 20 to make up a string member 11. A ball splitting method for ball parts fitted on the cord part of the string member includes: a step where blades 42b, 42b of a pair of ball-splitting molds 42a, 42a abut on outer peripheral surfaces of different-pitch ball parts 13 among a plurality of ball parts 13 used for a mechanism preventing the string member from falling off the connecting member; and a step where a force-applying mechanism applies a force to the pair of ball-splitting molds 42a, 42a in a direction in which the pair of blades 42b, 42b get close to each other to split the different-pitch ball parts 13. A distance between tips of each of the pair of blades 42b, 42b is formed so as to become slightly larger than a diameter of the cord part 12 when the pair of blades 42b, 42b get closest to each other.SELECTED DRAWING: Figure 5
【課題】コード部を傷付けることなく、比較的容易にピッチの異なるボール部を割ることができる。【解決手段】紐状に形成されたコード部12を連結部材20により連結して紐状部材11が構成される。この紐状部材の連結部材からの抜止め構造に用いられる複数のボール部13のうちピッチの異なるボール部13の外周面に一対のボール割り型42a,42aの刃42b,42bをそれぞれ当接させる工程と、力付与機構が一対の刃42b,42bを互いに近付ける方向に前記一対のボール割り型42a,42aに力を付与してピッチの異なるボール部13を割る工程とを含む紐状部材のボール部に嵌着されたボール部のボール割り方法である。一対の刃42b,42bが最も近付いたときに、一対の刃42b,42bの先端間の距離がコード部12の直径より僅かに大きく形成される。【選択図】図5
