Abstract

This is an improvement to the construction of a golf club composed of a head and of a shaft. <??>The neck part (11) included between the shaft (20) and the head (10) is made stronger by moulding the shaft and the head in the same mould. As a variant, the shaft and the head may be moulded separately and the assembly join is encased in fibrous layers of material impregnated with resin which, after polymerisation with heat, provides a bond with cohesive effect.
