Abstract
A drive assembly for a stalled roll sheet feeding device is illustrated. It comprises a registration roll and a feed roll driven in timed sequence each with a control collar comprising a clutch to engage and disengage the respective shaft and each collar having control stops positioned to interact with a control arm pivotally mounted between them which with a solenoid actuator selectively pulls one end of the control arm down releasing the other and, when the solenoid is deenergized a spring positively retracts the control arm from engagement with the control collar. In a preferred embodiment the sheet feed roll comprises a segmented feed roll and a cam actuated spring is used to multiply the positive retraction force supplied to the control arm when it is retracted from engagement with the control collar.
