Abstract
A method of moulding racquets to define stringing holes in the moulded frame. The method includes forming at least one approximately ladder-shaped member having two side pieces interconnected by rung pieces, with the side pieces substantially conforming to the curved shape of at least part of the frame of the racquet; entrapping the ladder-shaped member between two mould plates defining a mould cavity; injecting a plastic material into the mould cavity to mould the frame around the rung pieces; and forming the ladder-shaped member in two parts and separating the two parts after the frame has been moulded to remove the ladder-shaped member from the moulded frame.
