Abstract
A regulated length take-up device characterized by its substantially reduced width to be compact and simple structure, offering accurate regulated length take-up operation. A rotating lever is connected to the shaft of a take-up roll via a one-way clutch. Connected to the rotating lever is a cylinder mechanism which allows the take-up roll to rotate for the take-up operation along with the cylinder pull-in action. A sensor lever 32 capable of oscillating in accordance with variations in the take-up diameter of the take-up roll, is disposed in a manner that the orbit of the oscillation of the sensor lever agrees with the direction of the stroke of the cylinder mechanism. Along with a stopper disposed on the sensor lever to face the restoring action of the rotating lever, a cam curvature portion is formed on the rotating lever so that the cylinder stroke is constrained to keep constant the take-up length at every position over the orbit of the stopper regardless of variations of the take-up diameter of the take-up roll.
