System for attaching the free end of a spool thread

A method for implementing a system for fastening a free end of a spool of thread, wherein the system comprises:

• a support means for the spool;
• a needle comprising at an end of the needle:
• a hook and a mechanism for opening/closing the hook, the needle being oriented along an axis substantially parallel to the axis of the spool, wherein the needle is axially pivotable and axially translatable;
• and
• retaining mechanism in position of a turn of the thread of the spool;
• wherein the method comprises:
• a hooking step, by the hook of the needle, of a turn of the thread of the spool, which precedes a turn bearing the free end of the thread;
• a step of axial pivoting of the needle so that a hooked portion of the thread forms a loop;
• a step of axial translation of the needle through the loop of thread made, the translation being carried out so that the thread is released from the hook of the needle;
• a hooking step, by the hook of the needle, of the turn bearing the free end of the thread of the spool;
• a pulling step of a portion of the turn bearing the free end of the thread of the spool through the loop of thread made by the portion of the turn of the thread of the spool which precedes the turn bearing the free end of the thread;
• and
• a releasing step of the thread hooked by the hook of the needle.
