Abstract
Sheet counting apparatus includes a set of rotatably mounted suction spindles mounted for movement past a stack of sheets to be counted. A vacuum is connected to the spindles. As a suction spindle passes the stack, the vacuum is supplied to the spindle so that the topmost sheet is deflected from its initial position. A monitor monitors the number of deflected sheets by monitoring the degree of vacuum within the suction spindle passing the stack. The monitor increments a count on each occasion when the monitored vacuum exceeds a predetermined level threshold for a predetermined time.
