Abstract

The invention relates to a method for producing a sheet of fibrous material, comprising the step of producing thin elements (5, 10) of fibrous material and of combining the thin elements with one another in order to form a sheet in which one of at least the thin elements (5) is discontinuous and forms isolated portions of fibrous material.
