    摘要: A glue delivery system and method for providing precise application of glue on a substrate. A bead of glue is extruded from a first glue chamber through a gun to a leading edge of the substrate. A trailing edge of the substrate is blown off and over to the nozzle to receive a smear of glue from a second glue chamber. A gear pump is controlled by a servo drive that is connected to a servomotor utilizing a gear reducer. The pump regulates the extrusion of the glue onto the substrate that is programmed with empirical data of gear reducer ratio at which the glue flows within a constant speed, torque, current, speed and position of the glue. The empirical data is provided to a programmable logic circuit to achieve a precise pressure related to volume of a glue deposition and speed of the substrate onto which the glue is applied.
