Abstract
The invention concerns a method of SZ stranding into one strand a bundle of two or more flexible micromodules, each micromodule comprising one or more optical fibers. A first pulley is located with its winding surface adjacent to a longitudinal axis of a cabling line. The bundle of micromodules is guided over the winding surface of the first pulley, the first pulley being rotating around the longitudinal axis of the cabling line. The rotational speed, or the rotational direction of the first pulley, is alternating.
Claims15
A method of SZ stranding into a one strand bundle at least two flexible micromodules, each micromodule comprising an optical fiber, the method comprising:
- providing a device configured to SZ strand the at least two flexible micromodules into the one strand bundle, the device having a longitudinal axis and a first and second pulley positioned along the longitudinal axis of the device;
- the first pulley is located with its winding surface adjacent to a longitudinal axis of a cabling line;
- the second pulley is located with its winding surface adjacent to said longitudinal axis of the cabling line, upstream said first pulley and on an opposite side of said longitudinal axis, and
- guiding the bundle of micromodules along a longitudinal axis of the device between the first and second pulley and winding the bundle of micromodules around the winding surface of said first pulley and subsequently guiding over and winding the bundle of micromodules around the winding surface of said second pulley, while said first and second pulleys are simultaneously rotating around said longitudinal axis of the cabling line, wherein:
- the rotational speed of said pulleys, or the rotational direction of said pulleys around said longitudinal axis, is alternating thereby forming the SZ stranded micromodules into the one strand bundle, and
- including holders attached to a hollow crossbar that position the first and second pulleys outside of the hollow crossbar such that the hollow crossbar is in between the first and second pulleys.
A device for SZ stranding into a one strand bundle at least two flexible micromodules, each micromodule comprising an optical fiber, wherein it comprises:
- a first pulley, which is located with its winding surface adjacent to a longitudinal axis of a cabling line and which rotates around said longitudinal axis of the cabling line;
- a second pulley, which is located with its winding surface adjacent to said longitudinal axis of the cabling line, upstream said first pulley and on an opposite side of said longitudinal axis;
- a guide that guides said bundle of micromodules in between the first and second pulley along a longitudinal axis of the device, first over the winding surface of said first pulley, and subsequently over the winding surface of said second pulley, so that said bundle of micromodules winds around the winding surface of said first and second pulleys, while said first and second pulleys are simultaneously rotating around said longitudinal axis of the cabling line;
- and
- a motor configured to alternate the rotational speed of said pulleys, or the rotational direction of said pulleys to produce SZ stranded micromodules into the one strand bundle, and
- including holder attached to a hollow crossbar that position the first and second pulleys outside of the hollow crossbar such that the hollow crossbar is in between the first and second pulleys.
