Abstract
The present invention relates to a system and method for transferring tissue reels. The system preferably incorporates nozzles that spray an adhesive directly onto moving tissue paper substrate, as opposed to applying adhesive directly to the reel, independent of machine speeds and basis weights of the substrate. Alternatively, the system of the present invention may also apply adhesive directly to the new reel as opposed to the tissue paper substrate. In the preferred embodiment, the new core or reel is brought up to substantially equivalent speed as the moving tissue paper substrate and placed into contact with the moving web of tissue. When the new reel is in place, the valves are activated thereby spraying adhesive across the width of moving tissue. The newly coated substrate sticks substantially immediately to the new core and cleanly tears away from the completed roll.
