Apparatus for delivering wire from a coil thereof to an associated machine comprises a shuttle which is driven positively around the coil to pick up wire therefrom and spring means for causing the coil to rotate as required to keep the wire taut but without undue tension therein if the demand of the machine varies. Wire W from a coil on a holder 19 passes over a shuttle roller 12 on an arm 11 on a hub 5 rotated by a shaft 1, driven by a shaft 35 driven from an automatic package banding machine which pulls the wire W under a roller 10 on the hub and over the shuttle 12. A spiral spring S1, Fig. 4A, secured to the shaft 1 and hub 5 normally holds a stop ' 2a on the shaft 1 against stop 5a on the hub 5 to rotate it. The coil holder 19 is rotatably mounted on bearings 23, 24 relative to the shaft 1 and has a collar 26 extending therefrom secured to one end of a spiral spring S2, Fig. 4B, the other end of which is secured to a boss 28 clutched by spring-loaded friction blocks 33 to the shaft 1. The spring S2 is normally loaded to hold a stop 28a on the boss 28 against a stop 26a on the collar 26. In operation as the shuttle 12 goes around the coil the coil is normally held stationary by the tension in the wire W, the clutch 33 slipping, the spring S1 unaffected, the stops 2a and 5a abutting, and the spring S2 being loaded to keep the stops 28a, 26a in contact. Should wire demand exceed supply the increase of tension in the wire W moves the shuttle 20 forward to load the spring S1 and turn the coil and its holder 19 in the reverse direction until the tension in the wire is normal again. Should the demand fall and the wire W slacken the coil holder 19 is rotated in the same direction as the shuttle by unloading of the spring S2 and by the clutch 33 until the tension is again normal.
