Abstract
An adjustment method for adjusting the heights of the nipping belts in a transport conveyor that moves flat articles in series and on edge, so that a transport height is substantially constant for the flat articles. The method causes the conveyor to operate empty in such a manner that the nipping belts of heights that are to be adjusted run without any flat article in the conveyor, emits two parallel and superposed light beams towards a belt of height to be adjusted, spaced apart by a certain distance equal to the width of the belt between the two opposite edges of the belt to be adjusted, the light beams emitted from a portable tool, and manipulate a tensioner adjusting the belt so as to move the belt heightwise while it is running empty until the two light beams intersect respective ones of the two opposite edges of the belt.
