DLD 400-400 at customer

The video shows a sortation line with multiple DLD 400-400 diverters.
The video also shows Pre-Sorting:
Pre-sorting means that a diverter is used at the beginning of the conveyor line (i.e. before the sorting points) to move the products already to the correct side of the conveyor belt.
Pre-sorting is mainly required when very narrow products are to be sorted on wide conveyor belts. So that the products have already covered a large part of the conveyor width before the exit points.
