Sewing Machine Drive
A magnetic encoder system of a sewing machine drive comprises a magnetic, magnetised disc with alternating north and south pole elements, which are used as incremental markings. The latter are designed as a full ring-incremental track, which extends around a circumference of the ferritic disc, and as an annular section incremental track, which is designed as an annular section on the ferritic disc. The result is a magnetic encoder system for a servomotor of a sewing machine.

Hook and bobbin locator apparatus and method
A hook and bobbin locator apparatus and method consisting of a mounting plate and more than one hook and bobbin combination. Each of the more than one hook and bobbin combinations is connected with a stepper motor and each of the more than one hook and bobbin combinations are removably connected with the mounting plate. A stepper motor is also connected with the mounting plate and a controller is connected with the mounting plate stepper motor and the hook and bobbin combination stepper motors such that movement of the mounting plate and the hook and bobbin combinations are controlled by the controller.
