Abstract
A machine for stacking mesh reinforcement grids alternatingly in initial and reversed orientations includes a frame on which the grids to be reoriented are held during the reversing operation. The frame is mounted on swivelling arms for swivelling therewith and for turning relative thereto between two positions, and the frame is turned through 180.degree. relative to the arms during their swivelling to one of such positions and held stationary relative thereto during the swivelling toward the other position. Guide rails are retractably positioned along the feed path of the grids to support those grids which are not to be reoriented, prior to the retraction of such rails which takes place before the release of the reoriented grid from the frame.
