Abstract (en)
[origin: WO8606286A1] The method for producing golf clubs comprises the fabrication of the club shaft from a plurality of different tubes of which one of them optionally conical is made of metal or synthesis fibres such as carbon fibres, boron fibres, glas fibres or aromatic polyamide fibres, and is nested into two other metal tubes of which one of them forms the support of club head (9, 10), and the other one forms the handle (11, 12) on lengthes respectively (l5, l6) and (l7, l8) such that the vibration frequency of the club, which depends on its flexibility, on a length (L5, L6) equal to its size minus a distance d from the top of the handle, is controlled.
