Abstract: Of the type of those which incorporate a portfolio (1), with its front wall (2), its rear wall (3) and its spine (4), to which is coupled a plurality of sheets or documents (9) provided with holes (10) next to one of their edges, it incorporates a narrow plate (5) joined to the internal face of its rear wall (3), next to its spine (4), from which plate (5) emerges a plurality of narrow toothed strips (6) of which are complementary respective headers (8) joined in turn to a second strip (7), physically independent of the portfolio (1), so that after coupling the sheets or documents (9) to the toothed strips (6), by passing these through the holes of the former, said toothed strips (6) are finally coupled to the headers (8) of the moveable plate (7), whereby the sheets (9) are definitively fastened and it is possible to proceed to the cutting of the surplus segment of said toothed strips (6).
