  • EXTERNAL COVER FOR A SPOOL OF THREAD TO PREVENT THREAD FROM FREELY COMING OFF AS THE SPOOL IS BEING USED
    Publication number: 20100108795
    Abstract: The invention is a restrainer for a spool (10) of thread to prevent the thread (13) from being freely drawn off of the spool (10). It comprises a resilient element (12) that extends around the circumference of the outer surface (14) of the spool (10) so that the thread (13) being drawn from the spool (10) must pass between the outer surface of the spool (10) at the inner surface of the resilient element (12) there by impeding the free removal of the thread (13). The invention prevents excessive thread being jerked from the spool.
