摘要

Device and method for forming a reserve of textile thread. The device (10) is arranged between a textile machine, which feeds thread (30) continuously, and a replaceable collection element (15). The device (10) comprises accumulation means (11) on which the thread (30) is wound and on which a reserve of thread (30) is formed. The device (10) also comprises synchronization means (26) to synchronize the speed of rotation of the accumulation means (11) with the speed of rotation of the collection element (15). The synchronization allows to balance, under normal working conditions, the quantity of thread that is wound onto the accumulation means (11) with the quantity given up to the collection element (15) and, in a situation when the collection element (15) is restarted, imposes a greater speed on the collection element (15) than that of the accumulation means (11) in order to recover the reserve of thread (30).
