ABSTRACT:
Method and apparatus for calibration and adjustment of an inserter working with air suction for picking up a sheeted or folded material one at a time from a bundle for insertion in a machine, wherein an inserter includes a variable air suction source to pick up a sheeted or folded material one at a time from a bundle for insertion of the picked up sheeted or folded material into a machine. A sensor (24) positioned adjacent the inserter transmits different output signals which correspond respectively to no sheet of material picked up, one sheet of material picked up or several sheets of material picked up. The variable air suction source of the inserter is controlled responsive to the output signal from the sensor such that the air suction source produces increased suction of the sensor output signal corresponds to no sheet of material picked up or decreased suction if the sensor output signal corresponds to more than one sheet of material picked up.
