A glue delivery system for extruding glue onto a moving substrate, the glue delivery system comprising: at least one glue holding container adapted to hold glue; a first glue applicator having a gun attached to a first glue chamber that is connected to the at least one glue holding container utilizing a first hose; wherein the glue delivery system is configured to extrude a controlled amount of glue from the at least one glue holding container through the first hose to the first glue chamber and to the gun and through the gun to a leading edge of the moving substrate placed in a leading edge pad of an applicator drum; and, a second glue applicator having a nozzle attached to a second glue chamber that is connected to the at least one glue holding container utilizing a second hose; wherein the glue delivery system is configured to extrude a controlled amount of glue from the at least one glue holding container through the second hose to the second glue chamber and to the nozzle, and to blow off a trailing edge of the moving substrate, placed in a trailing edge pad of the applicator drum, over to the nozzle to receive a smear of glue on the trailing edge of the moving substrate; and, wherein the glue delivery system further comprises: a servo drive, a servomotor comprising a main motor shaft, a gear reducer and a gear pump connected to the at least one glue holding container, the gear pump being precisely controlled by the servo drive, via the servomotor, utilizing the gear reducer; wherein the gear pump is configured to regulate the extrusion of the glue onto the moving substrate, the glue delivery system being characterised by the gear pump being programmed with data representative of gear reducer ratio at which the glue flows within a constant speed, torque, current, speed and position of the glue at a desired temperature, the gear pump being programmed to reference a data matrix including data representative of gear reducer ratio as a function of pressure applied to the glue as the glue is provided to the gun and nozzle to be extruded, said data matrix being created by recording data during an empirical data acquisition process representative of a measured amount of a calibration glue deposited onto the moving substrate, information relating to a signal indicating glue pressure drop, a torque and current empirical data related to the main motor shaft of the servomotor, a gear reducer ratio empirical data, and a speed of movement of the moving substrate relative to the applicator drum; wherein the glue delivery system is configured such that, when the glue pressure drops due to the extrusion of the glue onto the moving substrate, the torque and current on the main motor shaft of the servomotor drop, and the gear reducer ratio of the gear pump is changed to maintain a required torque and current on the main motor shaft of the servomotor, whereby the glue delivery system is configured to measure the glue pressure drop and to modulate the glue pressure based upon a differential between the changed gear reducer ratio and a predetermined gear reducer ratio, thereby achieving a precise pressure of glue deposition related to a volume of the glue deposition and speed of the moving substrate onto which the glue is applied. at least one glue holding container adapted to hold glue;
