Abstract
A feed mechanism for a sewing machine, either separate from the rest of the machine or incorporated as a part thereof, to feed fabric in any direction, that is programmable, and is easily controlled.
Claims17
A sewing machine feed device to cooperate with a sewing machine and feed a fabric in a desired direction comprising:
- a) a driving means for the sewing machine feed device being separately drivable in relation to the sewing machine;
- b) a feed mechanism feeding a sewn product independently of the sewing machine;
- c) a rotational component being adapted to feed a material to a sewing in a desired direction;
- d) the feed mechanism for the sewing machine being separate from the sewing machine or incorporated as a part thereof;
- e) at least one rotational component for the feeding mechanism feeding a material in the desired direction;
- f) the feed mechanism including at least one feed dog;
- g) the at least one feed dog moving in an elliptical path to transport the material over a throat plate;
- h) the feed mechanism including a vertical drive motor, a horizontal drive motor, and a rotational drive motor;
- i) a motor controller being cooperatively connected to the vertical drive motor, the horizontal drive motor, and the rotational drive motor;
- j) a programming device being cooperatively connected to the vertical drive motor, the horizontal drive motor, and the rotational drive motor;
- and
- k) an operator control panel being cooperatively connected to the vertical drive motor, the horizontal drive motor, and the rotational drive motor.
