Abstract (en)
[origin: US4646982A] A self-sustaining bobbin winding device for use in a sewing machine has a driving unit which carries the bobbin during winding of a thread onto its core, and such unit is driven by an electric motor which can be arrested in response to actuating of an electric switch. The switch is actuated by one arm of a three-armed lever another arm of which is caused to bear against the roll of convoluted thread on the rotating bobbin and initiates a stoppage of the motor when the bobbin has collected a preselected length of thread. The third arm of the lever can be depressed by hand to disengage the other arm from the convoluted thread and to actuate the switch at the will of the operator. A first thread cutting tool is provided on the third arm of the lever, and a second thread cutting tool is provided on the driving unit.
