Abstract
An embossing system is provided for embossing at least a portion of a web comprising a first roll and at least a second roll. The first roll and second roll may define a first nip for embossing the web. At least one of the first roll and the second roll has elongated embossing elements extending substantially in the machine direction and optionally at least one of the first and second rolls has elongated embossing elements extending substantially in the cross-machine direction. At least one of the first roll and the second roll may also have perforate embossing elements extending substantially in the cross-machine direction that may or may not be elongated. The embossing elements are capable of imparting one or both of a cube embossing pattern or a perforate emboss on the web. The web may be a cellulosic fibrous web, a portion of which is lignin-rich, high coarseness fiber having generally tubular fiber configuration. In addition, the web may be creped with an undulatory creping blade.
