This invention relates to a tension buffer system for multi-wirepay-off system. The tension buffer system comprises guiding pulleys () adapted to guide wires () being paid off, and reversing pulleys (). Each reversing pulley () is adapted to guide a wire () from the guiding pulley () and back to the guiding pulley (), two reversing pulleys () are rotatably mounted on a first support (), the first support () is pivoted around first support axis () lying between the two reversing pulleys () so that pivoting brings one of the two reversing pulleys () closer to the guiding pulley () while the other of the two reversing pulleys () more remote from said guiding pulley (). This invention provides a mechanical device to balance the tension difference between multiple wires in the pay-off system to produce a steel cord with constant tension and satisfactory quality.

Tension buffer system for multi-wire pay-off system

A system () for winding multiple elongated elements () simultaneously under a substantially same tension on a single spool () comprises one pendulum arm () and one set of actuators () acting on the pendulum arm () and balancing with the sum of tensions of each elongated element (). The system () further comprises one or more balancing arms (): A first balancing arm () is attached to the pendulum arm (), the other balancing arms (if any) are attached to the first balancing arm (). Each balancing arm () is pivotable upon a balancing arm axis (). A first set of one or more reversing pulleys () is positioned at one side of the first balancing arm axis () and a second set of one or more reversing pulleys () is positioned at the other side of said balancing arm axis (). Each of the reversing pulleys () guides an elongated element () to be wound.
