The nozzle bar applicator has been designed especially for the DVD application tower for roof vibration and sound damping mats. With the aid of the ATN-designed nozzle bar, a linear, comb-shaped material block can be applied to a workpiece. The nozzle block applies material to roof vibration and sound damping (DVD) mats in motor vehicles. Up to four application nozzles can be supplied with material by one dosing device. The diameter of the nozzles fitted is tailored to the customer’s needs. The integrated dosing units allow the material flow rates to be infinitely adjusted through speed-dependent control of the higher-level system. A connection to the higher-level control system allows individual control of the application nozzles and of the material heating.
