ABSTRACT:
Apparatus for measuring peel force exerted on optical fiber being pulled m a bobbin upon which it is wound, the pull being in the direction of the longitudinal axis of the truncated-conically-shaped bobbin. One end of an elongaged lever arm holds the bobbin cantilevered from the bobbin end opposite that from which the optical fiber is pulled so that the bobbin is positioned generally horizontally over a horizontal base to which the opposite end of the lever arm is pivotally attached. An intermediate point on the arm beneath the bobbin is in contact with a load measuring device so that as the fiber is pulled any reaction by the arm upon the device provides a measure of the peel force upon the fiber.
