| 摘要 |
The invention refers to a book structure (1) or other publishing product comprising a plurality of pages enclosed in a cover (2), two or more of which are formed by a folio page (3) having an extension larger than that of the area defined by the cover and subdivided by a first fold line (5) coinciding with the back, that is, with the central fold line of the cover (2), said folio page (3) being reversibly foldable to take up a format of minimum extension in which its area results included in the one defined by the cover (2), and a format of maximum extension in which it extends beyond the area defined by the cover in correspondence of one or two opposite edges, at least one portion of the outer face of said folio page (3) being glued to an immediately adjacent page; the folio page (3) exhibits at least a second fold line (4, 6) parallel to said first fold line (5) and at least a third fold line (7, 9) orthogonal to the preceding one, said lines coinciding with at least two edges of the area defined by the cover (2) beyond which edges said page (3) extends when the same is in open or not folded format. <IMAGE>
