Abstract:
An apparatus for directing a fluid in a selected pattern onto a moving substrate, said apparatus comprising:a nozzle connected to a rotatable servo arm and configured to direct said fluid on said moving substrate;supplying means for providing said fluid to said nozzle at a pressure which provides for a selected fluid flow rate from said nozzle;designating means for identifying a plurality of selected article lengths along said substrate;transporting means for moving said substrate at a predetermined speed along a machine direction past said nozzle during said directing of fluid onto said substrate;an actuating servo having a servo motor connected to rotate said servo arm, said servo arm transmitting a rotation of said servo motor to said nozzle to move said nozzle along a selected delivery path, and said servo motor including a passageway which allows a transport of said fluid through an interior of said servo motor; andregulating means connected to said actuating servo to control said servo motor by employing a selected, electronically stored data set which has a sequence of numbers with each number representing a desired motor angle provided for by said actuating servo motor, said data set configured to move said actuating servo motor to provide a selected sequence of rotational movements of said servo arm in a predetermined correspondence with movement positions of said substrate to thereby direct said nozzle along said selected delivery path and provide said selected pattern onto each selected article length of said substrate.
