摘要

An apparatus for emboss bonding two or more lightweight cellulosic webs 64 to form a multi-ply article, the apparatus including a first cylindrical roll 20 having preferably a metal surface and being disposed for rotation about a cross machine rotation axis 24 an etched area 26 of the surface of the first roll defining a pattern having predetermined dimensions for forming proximate the perimeter of the article an emboss bond, the etched area comprising a plurality of truncated right rectangular pyramidal cavities in the roll surface disposed in adjacent relationship in the machine direction and the cross machine direction, and a second cylindrical roll 60 disposed to cooperatively rotate with the first roll and to define therewith a nip 62 for engaging the webs, the second roll having an impressionable surface capable of confirming under pressure to the etched area or having an etched area defining a complementary pattern for meshing engagement with the etched area on the first roll. <IMAGE>
