Abstract
A stock advancing apparatus for advancing stock to or from a stock processing machine. The stock advancing apparatus includes a drive motor for driving the stock advancing apparatus and a stock loop control arm mounted for swinging movement and adapted to engage a stock loop intermediate the stock advancing apparatus in the stock processing machine, and mechanism responsive to swinging movement of the control arm controls operation of the drive motor to maintain a loop in the stock between the stock advancing apparatus and the stock processing machine. A control arm cam is mounted for movement with the stock loop control arm and a cam follower is pressed into engagement with the control arm cam by a spring. The control arm cam and cam follower and spring are constructed and arranged to apply torque to the control arm in a direction to oppose upward movement of the control arm and which increases as the control arm moves upwardly and decreases as the control arm moves downardly. Manually adjustable means are provided for adjusting the minimum deflection of the spring.
