Abstract

A winding system contains a let off stand, a winding coordinator, and a wind-up stand. The left off stand contains a tape holder and a generally planar base which rotates in a first direction. The winding coordinator contains a generally planar section having an opening for an elongated element and rotates in a second direction opposite to the first direction.

First claim

What is claimed is:

1. A method of winding comprising:
unwinding a single elongated element off a let off roll, wherein the let off roll is located in a let off stand comprising a roll holder and a generally planar base, wherein the roll holder is configured to hold a roll, wherein the let off roll has a generally cylindrical shape, a central axis, and a first and second parallel annular base perpendicular to the central axis, wherein the roll holder comprises a first leg configured to engage the let off roll at the first annular base and a second leg configured to engage the let off roll at the second annular base such that the let off roll is able to rotate circumferentially about the central axis of the let off roll, wherein the base is generally perpendicular to the first leg and second leg and is generally parallel to the central axis of the roll, wherein the base rotates in a first direction within the plane of the base with respect to the central axis of the let off roll:
passing the single elongated element through a winding coordinator comprising a generally planar section, wherein the generally planar section has an entrance side and an exit side, wherein the generally planar section comprises an opening which the single elongated element passes through, and wherein the generally planar section rotates in a second direction opposite to the first direction as viewed from the entrance side of the generally planar section, wherein the let off roll and the winding coordinator rotate at approximately the same frequency;
circumferentially winding the single elongated element on a wind-up stand comprising a spool core forming a hollow cylinder having a central axis, the hollow cylinder being a three-dimensional region bounded by inner and outer concentric cylindrical sections and two parallel annular bases perpendicular to the central axis, wherein the single elongated element comprises a plurality of twists, approximately one twist for each full circumferential winding rotation of the single elongated element within the hollow cylinder.

2. The winding system of claim 1 , wherein the plane of the base of the left let off stand is generally parallel to the floor.

3. The winding system of claim 1 , wherein the opening in the winding coordinator has a slit shape.

4. The winding system of claim 1 , wherein the elongated element is a tape element.

5. A method of winding comprising:
unwinding a single elongated element from a tape holder stand, wherein the tape holder stand comprises a tape holder and a generally planar base, wherein the tape holder is configured to hold elongated elements, wherein the base rotates in a first direction within the plane of the base with respect to the central axis of the let off roll;
passing the single elongated element through a winding coordinator comprising a generally planar section, wherein the generally planar section has an entrance side and an exit side, wherein the generally planar section comprises an opening which the single elongated element passes through, and wherein the generally planar section rotates in a second direction opposite to the first direction as viewed from the entrance side of the generally planar section, wherein the let off roll and the winding coordinator rotate at approximately the same frequency;
circumferentially winding the single elongated element on a wind-up stand comprising a spool core forming a hollow cylinder having a central axis, the hollow cylinder being a three-dimensional region bounded by inner and outer concentric cylindrical sections and two parallel annular bases perpendicular to the central axis, wherein the single elongated element comprises a plurality of twists, approximately one twist for each full circumferential winding rotation of the single elongated element within the hollow cylinder.

6. The winding system of claim 5 , wherein the opening in the winding coordinator has a slit shape.

7. The winding system of claim 5 , wherein the elongated element is a tape element.

8. The winding system of claim 5 , wherein the elongated element is a pull tape.
