Abstract

The directional guidance mechanism alters the travel direction of sheets of paper etc. It has a box (9) into which the sheet, travelling in a first direction (40) is guided. An air current is generated inside the box, driving the sheet out in the opposite direction. A suction device can also be provided in the box, drawing an edge of the sheet against the rear wall as it moves in the first direction by means of a second current. The two currents can be arranged to function alternately for controlled periods. A third current can be provided, driving the sheet against a narrow sidewall of the box as it moves in the second direction.
