ABSTRACT:
An apparatus for reversing an orientation of flat items includes a first conveyor driven with a first speed; a second conveyor adjoining the first conveyor such that items discharged by the first conveyor are introduced into the second conveyor; a third conveyor driven with a second speed and adjoining the second conveyor such that items discharged by the second conveyor are introduced into the third conveyor; a sensor for determining a moment when a trailing edge of an item leaves the first conveyor; and a control arrangement connected to the sensor and the second conveyor for driving the second conveyor with the first speed as an item enters the second conveyor from the first conveyor, for decelerating the second conveyor when the sensor determines the moment when a trailing item edge passes by, for reversing a direction of motion of the second conveyor after deceleration and for accelerating the second conveyor to the second speed as an item enters the third conveyor from the second conveyor.
