Definitions
- each of the middle layer sheets may differ from an adjacent middle layer sheet in one or more of strength, elasticity and tonnage applied thereto.
- the overlapped joint may be formed in a direction perpendicular to the longitudinal direction of the golf shaft.
- the overlapped joint may be formed in a direction inclined with respect to the longitudinal direction of the golf shaft.
- the middle layer may include a first middle layer having an overlapped joint inclined upwards with respect to the longitudinal direction of the golf shaft, and a second middle layer having an overlapped joint inclined downwards with respect to the longitudinal direction of the golf shaft.
- the inner layer may be formed by laminating double-layered sheets, each of which has grains angled at a predetermined bias.
- FIG. 5 is views illustrating a method of manufacturing a shaft for a golf club, according to another embodiment of the present invention.
- FIG. 6 is a perspective view of the shaft for the golf club manufactured by the method of FIG. 5.
