Abstract:
A method and apparatus for inverting planate articles, such as door and window assemblies, which are supported from below in the horizontal plane, such as at a workstation for carrying out fabrication procedures from above the article. The article is tilted to a near vertical position at a tilting station, moved horizontally away to provide clearance from the tilting station, rotated a half turn about its vertical axis, returned to the tilting station and tilted back to the horizontal attitude with the original underside now on top. A tilt table that rotates around a transverse axis intermediate its length supports the article at the horizontal and tilts it to the near vertical attitude. A carriage receives the tilted article from the tilt conveyer and supports it at the near vertical by a turntable on the carriage having supports that engages the leading end and back side of the article. The carriage is movable to and from a location a distance from the tilt table for rotating the turntable a half turn at that location.
