A method is provided for forming a paper web having both bulk and smoothness. The method involves forming an embryonic web of papermaking fibers on a foraminous forming member, providing a web support apparatus having a web facing side comprising a first web contacting surface and a continuous macroscopically monoplanar second web contacting surface, wherein the web support apparatus provides a difference in elevation between the first and second web contacting surfaces which is less than the thickness of the embryonic web, partially drying the web to a consistency of between about 50 percent and about 70 percent and imparting a predetermined pattern to a first surface of the web while maintaining a second surface in a substantially smooth, macroscopically monoplanar configuration.
L'invention concerne une bande continue de papier et un procédé de fabrication de ladite bande. Dans l'une des formes d'exécution, la bande continue de papier comprend une zone continue relativement plus mince et une pluralité de zones distinctes relativement plus épaisses. Ces zones relativement plus épaisses sont disposées dans le plan de la zone relativement plus mince. La bande de papier peut présenter une face à motifs et une face relativement lissée. Les structures du papier peuvent être séchées relativement rapidement et efficacement et présenter un pouvoir absorbant et une masse volumique apparente améliorés, tout en ayant une face relativement lissée.
