Abstract
An apparatus adapted to be used for the automatic handling of sheets from which leaflets are formed and which includes a transfer unit for conveying sheets, an accumulator station disposed adjacent the transfer unit and being adapted to receive sheets from the transfer unit and to accumulate the sheets in a stack, a sensor associated with the accumulator station and being adapted to generate a signal indicative of whether the height of the stack of sheets in the accumulator station is at least equal to a minimum height, a sheet feeder adapted to periodically remove sheets from the stack of sheets at a substantially constant rate and a control mechanism operatively coupled to the sensor and the sheet feeder. The control mechanism is adapted to cause the sheet feeder to remove the sheets from the accumulator station as long as the height of the stack of sheets is at least the minimum height as determined by the sensor, and the control mechanism is adapted to cause the sheet feeder to cease removal of the sheets from the accumulator station if the height of the stack of sheets falls below the minimum height as determined by the sensor.
