description The invention comprises a modular pattern roll for embossing a cellulosic fibrous structure. The pattern roll is made by assembling separate components, rather than being one piece and chemically etched according to the prior art. The pattern roll comprises a cylindrically perforate outer shell having radially extending protuberances inserted through the holes in the cylindrical shell. The protuberances are provided with an interference fit and/or, if desired, a shoulder at the proximal end to prevent the protuberances from being extruded and expelled through the hole and creating a missile hazard during operation. The center of the hollow cylindrically perforate shell is filled with a base roll and a radially expanding internal locking assembly, to prevent the protuberances from moving radially inwardly under the compressive forces which occur during operation.
