Abstract
A method of manufacturing laminated plates, pencil boards or shafts for utensils for writing, drawing or painting, wherein the method includes initially producing in a container a pulp essentially composed of raw material powder and/or fibers and water, wherein the pulp is essentially free of binding agent, applying the pulp onto a screen and predrying the pulp in layers in the form of webs or foils so as to form a non-woven fabric, rolling the fabric onto a roller, applying between the material layers a connecting layer of binding agent, adhesives and/or other additives and cutting, dehydrating and drying the resulting plates and subjecting the plates to further processing.
