Method for the manufacture of products made from fibrous material

A method for manufacturing plastic-free products, the method comprising:

• feeding raw fibrous material including fibers as a material flow, wherein the raw fibrous material is a cellulose fiber material containing cellulose fibers and a binding agent, the binding agent being a natural substance, and wherein the feeding of the raw fibrous material includes feeding the fibrous material as a combination of a plurality of material bands;
• roll forming the material flow including binding the fibers of the fed raw fibrous material into a coherent profile, and molding a cross-sectional profile of the profile into a blank with a desired cross-sectional profile by displacing the coherent profile between at least one roller pair or drum pair to form molded profiles of the plastic-free products, wherein the roll forming comprises pressing the material flow of raw fibrous material between successive ones of the at least one roller pair or drum pair, wherein the plurality of material bands are bound into each other during the roll forming;
• cutting products of a desired shape from the molded blank by aligning a cutting geometry of the products at a desired place on the blank and cutting the molded blank along an entire outline of each of the plastic-free products, each entire outline fully enclosing a corresponding one of the molded profiles,
• wherein the roll forming is implemented as hot pressing whereby the rollers or drums used in roll forming are heated and kept at a desired temperature during the molding,
• wherein the roll forming implemented as hot pressing comprises molding a surface structure of the profile at desired locations of the cross-section of the profile,
• wherein the method is free of any molding step that is performed both downstream of the roll forming and upstream of the cutting.
