1. A method of controlling twisting in ribbon material fed from a coil of ribbon material into a processing machine, the coil having a central axis perpendicular to a plane of the coil, the method comprising:
- pulling ribbon material from the coil in a twist-promoting direction, and continuously rotating the coil during the pulling step at a rotational speed selected so that a number of twists in the unwound ribbon is maintained below a predetermined number, said continuous rotation of the coil being at least in part other than by pulling said ribbon material from the coil.

Abstract
A method of controlling twisting in ribbon material fed from a coil of ribbon material into a processing machine. The coil has a central axis perpendicular to a plane of the coil. The method includes pulling ribbon material from the coil in a direction having a twist-promoting axial component relative to the plane of the coil and continuously rotating the coil during the pulling step at a rotational speed greater than zero so that a number of twists in the unwound ribbon is maintained below a predetermined number.

9. A method of controlling twisting in ribbon material fed from a coil of ribbon material into a processing machine, the coil having a central axis perpendicular to a plane of the coil, the method comprising:
-
pulling ribbon material from the coil in a twist-promoting direction, and continuously rotating the coil during the pulling step at a rotational speed selected such that the number of twists in the unwound ribbon is maintained sufficiently low so that the material is substantially untwisted at a downstream portion of an intake feed mechanism of the processing machine, said continuous rotation of the coil being at least in part other than by pulling said ribbon material from the coil. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A feed system of a processing machine for continuously feeding a coil of ribbon material thereto, the coil having a central axis perpendicular to a plane of the coil, the system comprising:
-
an intake feed mechanism for pulling the ribbon material into the processing machine, the intake feed mechanism being adapted to pull the ribbon material from the coil in a twist-promoting direction, and a turntable positioned upstream from the intake feed mechanism for supporting the coil, said turntable being driven continuously at least in part other than by said intake feed mechanism while the intake feed mechanism pulls the ribbon material into the processing machine. - View Dependent Claims (17, 18, 19, 20, 21)

22. A feed system of a processing machine for continuously feeding ribbon material thereto, the system comprising:
-
a turntable, a coil of said ribbon material mounted on the turntable, the coil having a central axis perpendicular to a plane of the coil, means for pulling the ribbon material from the coil into the processing machine, the pulling means being adapted to pull the ribbon material from the coil in a twist-promoting direction, and means for continuously rotating the turntable and coil to reduce twisting in ribbon material pulled from the coil. - View Dependent Claims (23, 24, 25, 26, 27, 28)

29. A method of controlling twisting in ribbon material fed from a coil of ribbon material into a processing machine, the coil having a central axis perpendicular to a plane of the coil, the method comprising:
-
applying a pulling force to the ribbon material of the coil to pull ribbon material from the coil in a twist-promoting direction, and applying a rotating force to the coil separate from the pulling force applied to the ribbon material to rotate the coil during the pulling step at a rotational speed selected so that a number of twists in the unwound ribbon is maintained below a predetermined number.
