ABSTRACT:
High bulk tissue webs are processed sequentially through separate calendering and embossing units to optimize the balance between sheet caliper for winding tension and embossing element height for pattern definition, resulting in embossed, high-bulk tissue products with improved embossing pattern clarity. The multiple step converting process enables the use of male embossing elements having a height of about 0.04 inch or greater. The tissue webs have a Residual Waviness value of 12 micrometers or greater, which is attributable to average surface waviness values for the spot embossments being about 30 micrometers or greater.
