  • Torque capstan that improves reverse oscillating lay (ROL) consistency during an optical fiber cable manufacturing process
    Patent number: 6575346
    Abstract: A torque capstan is provided for use in an optical fiber cable manufacturing process which enables reverse oscillating lay (ROL) length to be maintained. The torque capstan comprises a first portion having at least two pulleys rotationally mounted thereon, a second portion having at least two pulleys rotationally mounted thereon, and first and second drive belts mounted on the pulleys of the first and second capstan portions, respectively. Rotational motion is imparted to the first and/or second drive belts through a drive system that is coupled to a drive pulley of at least one of the first and second capstan portions. Rotation of at least one of the drive pulley(s) causes the respective drive belt 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.
