WEB EMBOSSING MACHINE ABSTRACT The web embossing machine of the present invention has two embossing cylinders brought close to one another for combining two paper webs by the pressure contact between mutually corresponding protrusions on the two cylindrical surfaces. The protrusions are in rows which present a pattern inclined relative to the axes of the respective cylindrical surfaces, i.e., in a helicoidal fashion and relative to a plane passing at right angle through said axes, and thus achieve a subsequent and progressive contact instead of a simultaneous contact throughout the row. The inclination relative to a plane passing at right angle through the cylinder axis avoids repetitive pressure actions on the pressure rollers cooperating with the embossing cylinders.
