A process and system for applying an adhesive to a core during the production of rolled paper products is disclosed. The system of the present invention is generally directed to the use of pumping devices that meter out constant volumetric amounts of an adhesive onto a core through a plurality of adhesive applicators simultaneously. The systems includes, for instance, a positive displacement pump system in which a fluid at substantially constant pressure is fed to a pumping device for dispensing the adhesive to a plurality of adhesive applicators in constant volumetric amounts.

System and process for dispensing an adhesive onto a core during the formation of rolled products

An apparatus and method for cleanly breaking a continuously advancing cellulose web includes a transfer fabric which supports and advances the cellulose web to a wind up zone. The transfer fabric forms a closed loop and is driven at a desired speed by a drive roll. At least two spray nozzles are arranged transversely across the advancing cellulose web as it is carried on the transfer fabric. The spray nozzles are capable of emitting a liquid under high pressure against the advancing cellulose web to form perforations across the width thereof. A plurality of hollow cores are independently and sequentially moved into position at the wind up zone to receive the advancing cellulose web. The hollow cores are located downstream of the spray nozzles and each hollow core is capable of accumulating a predetermined amount of the cellulose web. The apparatus further includes controls for activating the spray nozzles in timed sequence to the speed of the transfer fabric such that a predetermined amount of cellulose web can be accumulated on each hollow core to form a finished roll having a predetermined diameter. An assembly is also present for moving each of the finished rolls away from the advancing cellulose web while simultaneously moving a second hollow core into contact with the advancing cellulose web upstream of the finished roll. The contact by the second hollow core and the employment of vacuum increases the tension on the advancing cellulose web and causes the advancing cellulose web to cleanly break at the perforations and form a leading edge. A vacuum is then applied to the second hollow core which causes the leading edge of the advancing cellulose web to wrap onto it. The method encompasses the sequential steps required to break the advancing cellulose web using the above-identified apparatus.
