ABSTRACT:
An assembly for transferring a wound coil disposed around a first mandrel onto a second mandrel. The first mandrel is radially expandable between first and second outer diameters and the coil is wound onto the first mandrel when in its larger, first outer diameter which is larger than the diameter of the second mandrel. The two mandrels are disposed in side-by-side coaxial relationship and the diameter of the first mandrel is reduced for reducing the radial stress of the wound coil against the first mandrel for facilitating movement of the coil off the first mandrel and onto the second mandrel.
