摘要

Improved plane-map, which being of the type comprising a folded sheet in successive folds to obtain a rectangular format, is characterized in that the first fold is longitudinal and forms an overlapping dihedral that presents transversely and centrally a fold line that determines two wings, in which, parallel to the central pre-ply line, they present other pre-ply lines that determine successive enveloping folds in the same direction and from the end towards the center, so that after folding the ends, the folds on one side, fold towards those of the other, bending over the central pre-line line and also characterized by the impression of the face opposite to that of the map-plane, inverted in one of the parts of the dihedral overlapped with respect to the other, so that after successive folded part and part of the dihedral are in the same sense of reading.
