ABSTRACT:
A tape supply for supplying tape under constant tension is disclosed. The tape supply includes a mechanism for mounting a reel of tape. The reel rotates as tape is withdrawn therefrom. The tape supply also includes a roller mounted on a lever. The tape passes over the surface of the roller as the tape is withdrawn. The lever is pivoted to move the roller in opposite directions.
The tape supply also includes a torsion spring having two ends. One end of the spring is fixed against movement. The second end is coupled to the lever by a coupling mechanism so that: (a) the spring urges the lever in a first of the opposite directions to apply tension to tape passing over the roller; (b) the lever moves in the second of the opposite directions in response to an increase in tension on the tape, thereby torsioning the spring; and (c) the lever moves in the first direction in response to a decrease in tension on the tape, thereby relieving the torsioning of the spring.
In a range of torsioning of the spring, the coupling means compensates for the increase in torque produced by the torsioning of the spring, whereby the roller applies a constant tension to the tape in a given range of pivoted positions of the lever.
