Abstract
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.
Claims20
A hook and bobbin locator apparatus comprising:
- a. a mounting plate;
- b. more than one hook and bobbin combination, wherein each of said more than one hook and bobbin combinations is connected with a hook and bobbin combination stepper motor, and wherein said more than one hook and bobbin combinations are removably connected with said mounting plate;
- c. a mounting plate stepper motor connected with the mounting plate;
- and
- d. a controller connected with the mounting plate stepper motor and the hook and bobbin combination stepper motors such that independent movement of the mounting plate and the hook and bobbin combinations are controlled by said controller.
In a sewing machine, a hook and bobbin locator apparatus comprising:
- a. a mounting plate connected to said sewing machine;
- b. more than one hook and bobbin combinations, wherein each of said more than one hook and bobbin combinations is connected with a hook and bobbin combination stepper motor, and wherein each of said more than one hook and bobbin combinations is removably connected with said mounting plate and wherein thread is included in bobbins in each of said hook and bobbin combinations;
- c. a mounting plate stepper motor connected with the mounting plate;
- d. a drive motor connected with said sewing machine;
- e. an encoder connected with said hook and bobbin combination stepper motors, said mounting plate stepper motor and said drive motor,
- f. a controller connected with the drive motor, the mounting plate stepper motor and the hook and bobbin combination stepper motors such that independent movement of the mounting plate and the hook and bobbin combinations are controlled by said controller, and
- g. a thread break detector connected with said controller for detection of the absence of thread in a hook and bobbin combination.
A hook locator method comprising:
- a. providing a mounting plate and more than one hook and bobbin combinations, wherein each of said more than one hook and bobbin combinations is connected with a hook and bobbin combination stepper motor, and wherein said more than one hook and bobbin combinations are removably connected with said mounting plate;
- a mounting plate stepper motor connected with the mounting plate;
- and a controller connected with the mounting plate stepper motor and the hook and bobbin combination stepper motors such that independent movement of the mounting plate and the hook and bobbin combinations are controlled by said controller;
- and
- b. operating the controller so as to move the hook mounting plate to reposition the more than one hook bobbin combinations.
