The invention relates to a process for manufacturing a laminated material (S) comprising a fibrillated cellulose layer, characterized in that it comprises the following steps: (a) depositing a suspension () of fibrillated cellulose on a filtration membrane () and draining the suspension through that membrane so as to form a wet layer of fibrillated cellulose (A) having a dryness, that is to say a ratio between the mass of dry matter and the total mass of the fibrillated cellulose layer, of between 5% and 18%; (b) transferring the wet layer (A) under pressure to an at least partially hydrophilic surface of a substrate (B), so as to form the laminated material (S); (c) drying the laminated material. The invention also relates to a device for implementing the process.
