A right angle turn module having a first transport that transports side-by-side sheets in a first direction. Downstream of the first sheet transport a barrier (42) is positioned to stop the sheets. A sensor device (62) detects an arrival of the side-by-side sheets at the barrier (42). Then, an actuated second sheet transport, triggered by the sensor device (62), is activated to transport the sheets serially in a second direction substantially perpendicular to the first direction. In a preferred embodiment, a horizontal guide plate (16) is positioned at a downstream end of the first sheet transport. With the guide plate (16) thus positioned, a sheet traveling in the first direction and a sheet traveling in the second direction can temporarily be overlapped and a collision can be avoided. In a further preferred embodiment, the first transport further comprises overhead belts to urge the side-by-side pair of sheets in the first direction. The overhead belts may be tensioned so as to slip over a top surface of the side-by-side pair of sheets while urging the pair of sheets towards the stop arrangement.
