ABSTRACT:
A strand tension controller which has an elongate strand sensing lever arm having a strand guiding input end and an opposing strand guiding output end with a tension shoe positioned between the input end and the output end of the lever arm for applying tension between a range of zero and a preset maximum tension on the strand. The lever arm is pivoted adjacent the strand engaging output end pivotal movement responsive to strand tension sensed at the opposing strand engaging input end of the lever arm and for subtracting from the tension applied by the tension shoe. The tension is sensed on the strand at the input end of the lever arm. The tension shoe engages a first surface of the lever arm and the strand passes along the top surface of the lever arm from the input to the output end of the lever arm. A pressure responsive expandable fluid reservoir in the form of an air tube controls the force applied to the strand.
