Title:

TORQUE CAPSTAN THAT IMPROVES REVERSE OSCILLATING LAY(ROL) CONSISTENCY DURING OPTICAL FIBER CABLE MANUFACTURING PROCESS

Document Type and Number:

Japanese Patent JP2003021762

Kind Code:

A

Abstract:

To provide a method for ensuring that ROL is consistently maintained during a manufacturing process, thereby decreasing or eliminating cable failures that often result from ROL inconsistency.

The rotation of at least one of drive pulleys causes respective drive belts to rotate in a direction parallel to, or substantially parallel to a direction in which an optical fiber cable being manufactured in the optical fiber cable manufacturing process is being pulled. Contact between the drive belts causes the drive belts to rotate in the same direction. At least one of the first and second drive belts has a longitudinal groove formed therein in a direction parallel to, or substantially parallel to, the direction in which the optical fiber cable is being pulled. The belts grip and pull/push the cable in such a way that the ROL length is maintained over the entire length of the optical fiber cable, thus improving the quality of the manufactured optical fiber cable.
