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. The carriage is returned to the tilt table location for transfer back to the tilt table for tilting back to the horizontal in the inverted mode.
