The Wald-Utal Applicator system utilizes servo-controlled nip rollers to drive the substrate, providing precise motion control and eliminating unnecessary drag on the substrate. The precision servo drive control and photo sensor registration automatically compensates for registration drift in real time without the need for user intervention or manual adjustments. Using a series of highly accurate sensors, the applicator system checks each printed graphic for the proper pitch (length) and automatically adjusts the web tension and other system variables on-the-fly to compensate for any detected variance. This system incorporates automatic edge-sensing and web guiding to ensure acurate sheeting placement on the aluminum substrate. The Wald-Utal Applicator system utilizes industry strandard web-guiding units to ensure optimal performance.
