surface to thereby form raised portions (embossments 26) and
corresponding recessed portions in the second ply, positioning
the first and second pairs of rolls such that the rigid
embossing rolls are adjacent one another forming a nip region
between the protuberances on each, applying an adhesive (via
adhesive applicator 23) to the web carried by the first
embossing roll and adhering the first ply and the second ply
to one another in the nip region wherein at least a portion of
the raised portions of the first and second plies are adhered
to one another and the recessed portions of the first and
second plies are spaced from one another.
