Abstract (en)
[origin: EP0313039A2] In the folding of a paper web (3), to which a fold-assisting liquid is applied along the fold line before the folding operation, a precise, sharp fold can be achieved and, at the same time, the risk of tearing and damage can be avoided by a method whereby the fold-assisting liquid is preferably water which is warmed by means of a flow heater to a temperature of the order of magnitude of 30 DEG C to 60 DEG C, depending on the paper type. <IMAGE>
