Patent ID: 6976651

Claim:
A method of affecting the transfer of an advancing tissue web from one take-up reel to another in a winding unit of a paper machine utilizing a tissue transfer device comprising an adhesive source, at least one adhesive manifold, and a plurality of valves coupled to the adhesive source via the adhesive manifold, each of said valves in communication with a corresponding atomizing nozzle arranged across a widthwise dimension of said advancing web, said method comprising: providing an adhesive in said adhesive source; heating said adhesive in said tissue transfer device to at least about 150° F.; pressurizing said adhesive in said tissue transfer device so as to supply adhesive to said valves at a pressure selected from a value between about 1000 psi and about 2500 psi; accumulating a sufficient amount of said pressurized adhesive in at least one accumulator coupled to said manifold to reduce undesirable pressure drop from said adhesive source and said manifold so that adhesive may be supplied through said valves at said selected pressure over a duration of between about 100 ms and about 500 ms; transferring said pressurized and heated adhesive to said plurality of valves to enable airless dispensing of said adhesive there from; and controlling said plurality of valves so as to dispense said adhesive from said atomizing nozzles across said widthwise dimension of said advancing web in an airless manner in intervals characterized by a duration between about 100 ms and about 500 ms.
