ABSTRACT:
A control system for an elastomer extrusion and application apparatus (10,16) including an extrusion rate measuring device (60,200) for receiving a ribbon (12) of extruded elastomer and for providing a signal representing the rate of extrusion, a drive (18) for moving an article (14) to have the ribbon of extruded elastomer applied thereto in a predetermined path, an applicator (16,20,22) along the path for receiving the ribbon and applying the same to the article, a resolver (176) connected to the applicator for providing a signal representative of the rate of application of the ribbon to the article, and a control (FIG. 5) for controlling the speed of the article drive including a circuit for receiving the signals and adjusting the speed of the drive to match a desired proportion between the rate of extrusion and the rate of application.
