<p>A method and apparatus for embossing elongated fibrous webs such as paper towels or toilet tissue, in which the longitudinal tensile strength is reduced by embossing such that after embossing it is more nearly equal to the transverse tensile strength. During embossing, selected portions of the embossed pattern are embossed more deeply to fracture fibers extending longitudinally. An improved paper product is thereby formed having a longitudinal transverse tensile strength ratio which is closer to 1:1.</p> |
