The invention relates to moulded plastics shuttlecocks and aims to provide a moulded shuttlecock that resembles a Feather shuttlecock in appearance and simulates feather shuttlecock flight properties more closely than conventional moulded shuttlecocks. The visible effect is achieved by moulding a skirt structure having a diverging array of stems (5) and a vane area (4) at the outer part of the skirt, the vane area being a series of half leaves (7) and part half leaves (8), one attached on either side of each stem, the leaves being shaped to appear as overlapping feathers but without any actual overlap occurring. The desired flight properties are achieved by separating each half leaf and its associates part half leaf along part of the boundary line (10) where they would otherwise appear to overlap and forming these separated portions in different planes. |
