Abstract
1313013 Dart flights T I RIDGWELL 26 May 1971 [11 June 1970] 28337/70 Heading A6S A dart flight is formed from a square sheet, e.g. of polyester, Fig. 5, which is formed with valley folds along lines 34 and ridge folds along diagonals 32, the four half-diagonal folds 32a-d then being brought into coincidence so that adhesive, applied to the internal surface of the folded shape, holds the final form of the flight. The four vanes of the flight may be trimmed to the form shown in Fig. 1. The flight is held in slits 15 formed in the shank 13, which may be of cane or fibreglass material. Insertion of the flight into the slits 15 may be limited either by a ferrule positioned on the shank, Fig. 4 (not shown), or by a ferrule positioned in a cut-out formed in the flight, Fig. 3 (not shown).
