ABSTRACT:
The stack of sheets is moved towards the distributor at a control velocity corresponding to the distributor operation. If the stack in the operative vicinity of the distributor becomes too low, indicating too slow a stack advance, a mechanical sensor sensing the position of the top of the stack rotates to a position interrupting the signal furnished by the first and second inductive input signal generator. The interruption of the signal results in the furnishing of a second sensor output signal which, at a time determined by a synchronizing signal sets a monostable multivibrator whose output then energizes a relay which in turn applies voltage to a winding of a servomotor moving the arm of a potentiometer in a direction for increasing the speed of advance of the stack. Similarly, when the stack is too high, neither of the signals from the inductive generators is interrupted and a third sensor output signal generated in response to the presence of the two signals similarly causes the servomotor to drive the potentiometer in the opposite direction thereby retarding the speed of transport of the support means carrying the stack. Since the feeder system has first and second support means so that sheets are continuously available to the distributor means, the system also comprises a number of control switches and an additional sensor for connecting the different support means to corresponding motors and for switching the first support means from an induction motor effecting a rapid transport to a DC motor effecting the controlled transport when the stack is within a predetermined distance of the distributor means.
