Abstract:
In combination:a) a bobbin assembly comprising: i) a core around which a supply of thread can be wrapped, the core having a rotational axis; ii) a first flange having first and second oppositely facing surfaces, the first surface bounding a storage space for thread wrapped around the core; and iii) a magnetic element; b) a support for the bobbin assembly, said support comprising: i) a third surface comprising a first metal material facing the second surface with the bobbin assembly operatively connected to the support and sufficiently close to the magnetic element so that a magnetic field is generated between the magnetic element and first metal material so as to generate a force that resists movement of the bobbin assembly relative to the support around the rotational axis of the core to a degree that the force does not significantly impede free relative rotation between the bobbin assembly and support but resists rotation to reduce the likelihood of thread backlash; and c) a loop taker for drawing thread off of the bobbin assembly by causing rotation of the bobbin assembly.
