YARN TENSION DEVICE

摘要

The invention concerns a yarn tension device (B) comprising a brake disc (L) eletromagnetically stressed against a fixed braking surface (17), a housing (1) whereon the cover bearing the brake disc (L) is mounted such that it is capable of being lifted relative to the braking surface (17), and at least an adjusting arbor (S) controlling the movements lifting the cover, said arbor being mounted on the housing (S) in geometric coordination relative to the path of the yarn (W). The invention is characterized in that the cover is a hinged cover (K) mounted to as to be capable of being raised about the adjusting arbor (S) while releasing the braking zone (12) of the yarn tension device (B).
