Publication number: 20090220703Abstract: The invention relates to an operating method for an atomiser (1) for the coating of structural components, particularly of vehicle body parts, with the following steps: Application of a spray jet of a coating agent through the atomiser (1); discharge of a first guide air flow (11) for the formation of a spray jet; determination of at least one application parameter (?, ?, T, BC/CC, Qvarnish, n, U,) which reproduces a property (?, ?, T, BC/CC) of the applied coating agent or an operating variable (Qvarnish, n, U) of the atomiser (1) as well as influencing of the first guide air flow (11) as a factor of the application parameter (?, ?, T, BC/CC, Qvarnish, n, U,). Within the framework of the invention, there is the alternative option that fluctuations of the application parameters and, based thereon, variations of the spray jet width are taken into account by means of an adaptation of the path spacing (d) between the adjacent coating agent paths for the purpose of keeping the path overlapping constant.Type: ApplicationFiled: September 19, 2007Publication date: September 3, 2009Inventors: Benjamin Wöhr, Hans-Jürgen Nolte, Andreas Fischer, Peter Marquardt, Frank Herre, Marcus Frey

Publication number: 20070082143Abstract: A coating means supply device, in particular for a paint facility, having a coating means meter that meters coating means to be applied to application equipment. The coating means supply device includes a coating means reservoir for holding the coating means and for supplying the coating means meter with the coating means. During application of coating material to equipment, the coating means reservoir is at ground potential and is located upstream from the coating means meter, which is at high-voltage potential. The reservoir is connected via an insulating path to the coating means meter.
