Patent number: 8020784Abstract: A coating material supply device is disclosed, such as for a paint facility. An exemplary coating material supply device may include a coating material reservoir and a coating material meter. During application of coating material, the coating material reservoir may be at ground potential and may be located upstream from the coating material meter, which may be at a high-voltage potential.

Patent number: 7213290Abstract: The invention concerns a pig scraper for cleaning the inside wall of a coating agent conduit. The pig scraper includes a body insertable in the conduit and at least one sealing lip that seals against the inside wall of the conduit and extends parallel to a longitudinal axis of the body. A space is defined between the sealing lip and the body to form a pocket for enhancing the sealing of the sealing lip with respect to the conduit. The length of the sealing lip substantially prevents the lip from folding over on itself in response to a change in the direction of movement of the pig scraper in the conduit.Type: GrantFiled: May 15, 2006Date of Patent: May 8, 2007Assignee: Durr Systems, Inc.Inventors: Herbert Martin, Werner Schwager, Martin Stiegler, Andreas Collmer, Manfred Michelfelder

Publication number: 20060254510Abstract: The two sealing lips of a pig, which is driven by a pushing medium for delivering a coating material for the mass-production coating of workpieces, have a self-sharpening sealing edge contacting the inner wall of the piggable line. Flat outer surface parts of the sealing lip formed ahead of and behind the sealing edge are angled against the inner wall of the line for an unloaded pig, while the inner surface part in the axial direction is pressed flat against the line under loading by the pushing medium. The production of the pig is realized through turning and subsequent shaping of the sealing lips in a transport sleeve in which the pig is kept and brought to its insertion location.Type: ApplicationFiled: May 15, 2006Publication date: November 16, 2006Inventors: Herbert Martin, Andreas Collmer, Martin Stiegler, Manfred Michelfelder
