<p>The assembly to form a flow (5) of partially overlaid printed sheets (4), especially folded sheets, has a feed wheel (1) after the folder to lay them in sequence on a conveyor belt (2). At least one electronic camera (6) checks the alignment of the sheets on the conveyor, with images taken at time intervals.

The control sets the conveyor and wheel speeds to maintain a constant sheet overlay gap (a).</p> |
