Abstract: 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 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.

Abstract: A linear stream of articles is conveyed to a processing station, a first one of said articles positioned in front of and in physical contact with a second one of said articles and the second one of said articles positioned in front of and in physical contact with a third one of said articles. A motor-driven rotary star wheel moves one-by-one said articles from a conveyor to a downstream processing station and is assisted in separating adjacent articles by a passive star wheel with a plurality of contoured arms separated by concave pockets. The passive star wheel receives one-by-one said articles in adjacent pockets and the contoured arms of the passive star wheel separate each article from the next following article. A guide section causes each article being separated to more along a generally tangential path relative to both star wheels as they rotate.
