摘要： A multi-spindle fiber pay-out apparatus (5) having a plurality of fiber spools (9) with each spool (9) having a fiber tension controller. The spindles (21) are in rotational supporting relation to the spool (9) of fiber and operatively engaged with a plurality of magnetic particle brakes (31) which are in communication with an electronic controller (99). A fiber take-up system (29) is mounted upon the frame (6) in cooperative relation to the spool (9) of fiber (7) and is arranged so as to compensate for changes in the fiber pay-out rate from the spool (9) of fiber (7) that are caused by activation/deactivation of the magnetic particle brake (37). A load cell transducer (13) is mounted on the frame adjacent to the fiber take-up system (29). The load cell transducer (13) is at least partially engaged by a fiber (7), and is arranged in electrical data communication with the magnetic particle brake (37) so as to (i) activate the magnetic particle brake (37) when a tension in the fiber (7) is detected below a predermined magnitude, and (ii) deactivate the magnetic particle brake (37) when the tension in the fiber (7) is at or above the predetermined magnitude. A method is also provided for monitoring and adjusting the length of a fiber (7) via monitoring of the tension of the fiber (7).
