Patent ID: 7220331

Claim:
A device for binding a multilayer cellulose fiber material band using ultrasonic wave emissions, said device comprising: a first in-feed apparatus comprising a source of a flat first individual cellulose fiber material band; a second in-feed apparatus comprising a source of a flat second individual cellulose fiber material band, said second in-feed apparatus being capable of profiling said flat second individual material band; means for aligning said first and second cellulose fiber material bands in direct contact without an intervening material as said bands travel in a running direction; an application apparatus for application of a liquid devoid of adhesive onto at least one of said first individual material band or said second individual material band to moisturize at least one of said material bands; and means for ultrasonically bonding said first and second cellulose fiber material bands directly together by inducing splicing together of fibers from said bands without an intervening adhesive material between said bands.
