Abstract
A system for isolating each end of a cylindrical coil wall from a tensioned binding medium employed to retain the coil wall in an axially compacted state. The system includes a magazine for containing a supply of pliable inserts. A feeding mechanism advances inserts from the magazine and along a guide for successive delivery to a clamp. The clamp is operative to releasably hold an insert received from the guide. The clamp is shiftable to position the insert in a gap between the end of the coil wall and a path along which a binding medium is directed prior to being tensioned. When the binding medium is tensioned, the insert is pulled from the clamp into a protective position tightly sandwiched between the tensioned binding medium and the coil end.
