Dual ply cellulosic fibrous structure laminate
Abstract:
An embossed paper laminate having two laminae. The laminae are embossed so that each embossed site of one lamina is adhesively joined to the nonembossed region of the other lamina. The laminate is made by two close tolerance pattern rolls juxtaposed to form a nip. Each pattern roll has radially extending protuberances which contact the periphery of the other pattern roll intermediate its protuberances. The laminae are fed through the nip in face-to-face relationship and are embossed and adhesively joined to the other lamina by the radially extending protuberances.
