ABSTRACT:
In a core assembly, a stretchable sleeve capable of recovering toward an initial unstretched configuration is supported on a hollow core. The core includes a plurality of structural elements connected by a plurality of linking elements that extend transversely of the structural elements. A mechanism is provided and connected to the distal end of the core whereby the core can be withdrawn from the sleeve in its axial direction by manipulating the mechanism allowing the sleeve to return to the initial unstretched configuration.
