<p>PCT No. PCT/EP90/00941 Sec. 371 Date Dec. 13, 1991 Sec. 102(e) Date Dec. 13, 1991 PCT Filed Jun. 15, 1990 PCT Pub. No. WO90/15670 PCT Pub. Date Dec. 27, 1990.A booth for the spray coating of workpieces with a powder coating material has a cleaning device for cleaning the interior of the booth. The walls, ceiling and floor constitute the interior contour of the booth and the cleaning device is dimensioned so that a working gap exists between the cleaning device carrier and the interior contour of the booth. The working gap is bridged elastically by cleaning elements that scrape the booth interior to dislodge powder material that has settled. A vacuum source connected to the cleaning device then sucks the powder material released from the interior surfaces for recycling of the powder and cleaning of the booth.</p> |
