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.
Claims26
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.
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.
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 powered turntable positioned upstream from the intake feed mechanism for supporting the coil, said turntable continuously turning while the intake feed mechanism pulls the ribbon material into the processing machine.
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.
