<p>A cone (8) on which thread (10) is wound has a central frangible section (12) at which it may easily be broken. The thread (10) forms a winding on the cone at each side of the section (12) leaving a space where it crosses the section (12). The cone (8) may be snapped in half to give two independent wound cone parts, each with approximately half the amount of thread. This allows the purchaser the flexibility to use the cone in various ways. In one embodiment, the cone parts may be urged axially together after the frangible section (12) has been broken, to become removably attached to one another with a reduced space between the respective windings.</p> |
