Patent

CA 2643604

Current sewing machines use two threads to sew a lockstitch. One thread is supplied from a main thread and the other thread is supplied from a bobbin thread. In this invention, the use of the bobbin is eliminated and the second thread is supplied from a second main thread. The removal of the bobbin will allow the sewing machine to be used continuously without the time delay of having to rewind thread on the bobbin or switch bobbins.
