ABSTRACT:
The invention concerns a triple mirror wheel. The construction steps consist in first making the individual parts of a triple mirror wheel, namely a core with ridges rotated by 180.degree. and each time adjacent to one mirror facet. Then two polygon rings are made, which as polygonal surfaces always evince the third facet of the triple mirrors. The core is moved concentrically between two polygon rings and the three parts are rigidly joined so that a triple mirror wheel with adjacent triple mirrors rotated by 180.degree. and with exceedingly sharp edges is formed in the individual triple mirrors.
