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