Abstract
A reel for use in making coils of wire and the like comprises a drum having two end flanges at least one of the flanges being detachable for removal of the coil from the drum which is itself formed of an assembly of segments radially displaceable between an expanded position for winding of a coil and contracted position for removal of the coil. The assembly includes slots in one end thereof and one of the flanges has spokes and is adjustable axially relative to the drum for setting the effective winding width to any one of a number of different sizes. The reel further comprises a support member located inwardly of the spoked flange to support each segment for radial displacement, the arrangement being such that during axial movement of the one end flange the spokes are accommodated in the slots in the assembly of segments. A modification of the reel provides also for adjustment of the effective diameter of the drum, in its expanded position, so that coils of different internal diameter can be wound using the same reel.
