embodiment 1

[0053]Embodiments of the invention are directed to a method and apparatus for cutting one or more grooves into an outer surface of a cylindrical element. A specific embodiment, which can be referred to as Embodiment 1, involves:

[0054]rotating a cylindrical element about a longitudinal axis of the cylindrical element;

[0055]where, while rotating the cylindrical element about the longitudinal axis, further incorporating:

[0056]moving a rough cutter and the rotating cylindrical element with respect to each other in a direction parallel to the longitudinal axis, where the rough cutter moves from a rough start position to a rough end position, wherein the rough start position has a rough axial start position along a length of the cylindrical element and a rough rotational start position about the longitudinal axis, where the rough end position has a rough axial end position along a length of the cylindrical element and a rough rotational end position about the longitudinal axis; and

second embodiment

[0063]In a specific embodiment, which can be referred to as the second embodiment, wherein the rough rotational end position is the same as the rough rotational start position, wherein the finish rotational end position is the same as the finish rotational start position, wherein the finish rotational start position is the same as the rough rotational start position, where while moving the rough cutter from the rough start position to the rough end position, the rough cutter is maintained at the rough rotational start position, where while moving the finish cutter from the finish start position to the finish end position, the finish cutter is maintained at the finish rotational start position, where rotating the cylindrical element comprises rotating the cylindrical element at a constant speed of rotation, where moving the rough cutter from the rough start position to the rough end position comprises moving the rough cutter from the rough start position to the rough end position at ...

fourth embodiment

[0070]In a further specific embodiment, which can be referred to as the fourth embodiment, incorporating the limitations of Embodiment three, the second finish axial start position is axially separated from the second rough axial start position by m leads, where m is an integer having a value of 1 or greater. In this way the second finish cutter follows in the groove started by the second rough cutter. In a specific embodiment, m=1.

[0071]In a further specific embodiment, which can be referred to as embodiment five, incorporating the limitations of Embodiment four, where the second rough axial start position is axially separated from the finish axial start position by (p+½) leads, where p is an integer having a value of zero or greater, where p=0.

[0072]In a further specific embodiment, which can be referred to as Embodiment six, incorporating the limitations of Embodiment 1, while rotating the cylindrical element about the longitudinal axis, further incorporating:

Abstract

Embodiments of the subject invention relate to a method and apparatus for cutting one or more grooves in a cylindrical element. In specific embodiments, the one or more grooves are cut into an outer surface of the cylindrical element. The cylindrical element can be solid, or can have one or more hollow portions. In a specific embodiment, the cylindrical element is a hollow tube. Embodiments also pertain to a cylindrical element having one or more grooves cut in an outer surface of the cylindrical element. Further specific embodiments are directed to cylindrical elements having one or more grooves that can be utilized as a drapery or curtain tube, where the one or more grooves, in combination with rotation of the cylindrical element, can be used for moving the drapery to one or more positions along the tube, such as from an open position for the drapery or curtain to a closed position for the drapery or curtain, by engaging an interconnecting element between the drapery or curtain and the one or more grooves while rotating the tube.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]The present application claims the benefit of U.S. Provisional Application Ser. No. 61 / 702,093, filed Sep. 17, 2012, which is hereby incorporated by reference herein in its entirety, including any figures, tables, or drawings.BACKGROUND OF INVENTION[0002]Embodiments of the invention relate to cutting one or more grooves in a cylindrical element.[0003]U.S. Pat. No. 4,125,057 (Cox) teaches a motor driven milling and boring machine used primarily for forming screw threads of any selected pitch, external to cylindrical or conic projection or within similar-shaped bore of workpiece, particularly workpieces such as are too large or irregular-shaped to be themselves rotated. A tubular housing, upstanding or tiltably disposable, journals a longitudinally displaceable and rotatable hanger which in turn axially journals a power-driven spindle having a selectively offset-positionable stub portion, terminally carrying a thus radially extensible drive ...
