Abstract (en)
[origin: EP3315442A1] In a resonance mode in which bending occurs at a bobbin holding portion 20, an increase in vibration by a mass for balancing is prevented or lessened. Positions of nodes N1 and N2 of the bobbin holding portion 20 in a predetermined resonance mode of a bobbin holder 9, in which bending occurs at the bobbin holding portion 20, are obtained. An unbalance corrector 25 for adding or removing a mass for balancing is provided at or around each node N1, N2, within a range of 10% of the length of the bobbin holding portion 20, the range being defined by taking the position of the node N1, N2 as the midpoint of the range.
