ABSTRACT:
A method and a spool (1, 10, 21, 22, 35) for shortening the length of a cord (14) and optionally tensioning it at the same time is provided. The spool has a shank having two ends each of which has a transverse retainer formation (4, 13, 20, 40, 51and5, 11, 25, 33, 36, 42, 49, 50, 58) adapted operatively to prevent unravelling off the shank of cord wound around the elongate shank, at least whilst it is held under tension and with the axis of the shank extending in the same general direction as that in which the cord extends. A keeper formation (4, 13, 20, 40, 51) that is preferably one in the same with the ring and a formation at one end of the shank cooperates with a cord to maintain said end in association with the cord whilst the shank is rotated to wind cord onto the shank by rotation thereof. A torque transmitting formation (5, 11, 25, 33, 36, 42, 49, 50, 58) that is preferably one and the same with the retainer formation associated with the other end of the shank enables rotation of the shank substantially about its own axis to be effected manually in the case that an integral handle is provided or by engagement thereof with a tool (44, 52). Typically, the length of the shank is from about 10 to about 50 times the diameter of the shank.
