Abstract (en)
[origin: EP3103749A1] The yarn tension is stabilized on a reference tension (T_ref) by a weft braking device (20) driven by a control unit (CU) that receives a measured tension signal (T_meas) from a tension sensor (22). The yarn consumption rate (YS_meas) is continuously measured and is continuously compared with a reference rate (YS_ref). If the difference between the yarn consumption rate (YS_meas) and the reference rate (YS_ref) falls within a predefined error range that indicates that the machine is operating with constant consumption, then adjust the reference tension (T_ref) so as to minimize the difference between the yarn consumption rate (YS_meas) and the reference rate (YS_ref), otherwise disable the adjustment of the reference tension (T_ref).
