ABSTRACT:
A method and apparatus for embossing paper products, such as paper towels or toilet tissue, in which the tensile strength extending in the machine direction is modified such that after embossing, the tensile strength in the machine direction is more nearly equal to the tensile strength in the cross-machine direction. During embossing, selected portions of the embossed pattern are embossed more deeply to fracture fibers extending in the machine direction, thereby modifying the tensile strength in the machine direction. An improved paper product is thereby formed having a machine direction:cross-machine direction tensile strength ratio which is more closer to 1:1.
