Improvements in the manufacture of cardboard sheets, which essentially consist of obtaining these sheets by means of the cross-linking of their component layers, using simultaneously flat formats, at the end of which, in one of the planned executions, at the exit of the press from the plowing roller and round sieve the endless felt is arranged in such a way that it continues its march horizontally, acting on flat formats that during its course are passed together under the action of a roller that works with sufficient pressure to detach the layer of paste that carries the felt and so that it is adhered on the flat formats.
