Abstract (en)
An apparatus for manufacturing multiple-ply paper products by knurling, having a knurling wheel unit constituted by one or more knurling wheels (4), each of which cooperates with a contrast roller (5) in order to decorate by knurling at least one paper ply and in order to decorate and join at least two paper plies. Each knurling wheel is provided with relief patterns (7) arranged so that despite appearing to be separate they allow the knurling wheel to have a continuity of contact with the paper and the contrast roller. <IMAGE>
