    摘要: A pre-wound bobbin for sewing, having a single flange or a pair of flanges, in which one flange of the bobbin comprises a magnetized material such that the flange magnetically adheres to the end wall of a steel bobbin case in which the bobbin is carried in a sewing machine. The flange is sized to provide a contact area with the end wall that, in relation to the magnetic strength of the magnetized material, achieves a magnetic attraction force exceeding the weight of the bobbin so that the bobbin is held in the bobbin case. The flange preferably is flexible.
