Overview
The folding process can also be carried out on already folded leaflets. The use of pre-folded leaflets entering the machine is used to process leaflets that would have been too large to be loaded. The folded leaflet, made by folding a sheet spread twice on itself in order to obtain a sheet divided into 3 parts with 6 sides, is one of the types of pre-folded leaflets that are loaded and folded in parallel by the in-line machine.
