Abstract
A self-compensating tension control device for regulating the payout of filamentary material from a spool includes a fixed support and a spindle assembly pivotably mounted to the fixed support, wherein the spindle assembly rotatably carries the spool of filamentary material. A pull-off force imparted by the filamentary material causes angular movement of the spindle assembly and rotation of the spool. A braking assembly mounted to the fixed support and coupled to the spindle assembly applies a braking force corresponding to an angular position of the spindle assembly.
