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.

A self-compensating tension control device for regulating the payout of filamentary material from a spool, comprising:
- a fixed support;
- a spindle assembly pivotably mounted to said fixed support, said spindle assembly rotatably carrying the spool of filamentary material, wherein a pull-off force imparted by the filamentary material causes angular movement of said spindle assembly and rotation of the spool;
- and
- a braking assembly mounted to said fixed support and coupled to said spindle assembly, wherein the amount of braking force applied by said braking assembly corresponds to an angular position of said spindle assembly;
- and
- a band having one end fixed a first distance from said fixed support in a first direction and an opposite end biasingly fixed at a second distance from said fixed support in a second direction substantially opposite said first direction, said band engaging said spindle assembly and applying a braking force thereto when said spindle assembly is in an angular position directed toward a shorter of said first and second distances.
A self-compensating tension control device for regulating the payout of a filamentary material from a spool, comprising:
- a fixed support;
- a spindle assembly pivotably mounted to said fixed support, said spindle assembly rotatably carrying the spool of filamentary material, wherein a pull-off force imparted by the filamentary material causes angular movement of said spindle assembly and rotation of the spool, said spindle assembly having a brake drum rotatable therewith;
- and
- a band mounted at both ends to said fixed support and contacting said brake drum, said band having one end fixed a first distance from said fixed support and an opposite end fixed at a second distance from said fixed support in a direction substantially opposite said first direction, said band engaging said brake drum and applying a braking force thereto when said spindle assembly is in an angular position directed toward a shorter of said first and second distances.
