Cardboard folder

摘要

The file cover (1) is wider than the back (2) by a strip (3) separated by a first fold (4). The tongue (6) pierces the side of the strip facing the rear of the file. The file rear is stuck directly to the cover and covers the tongue and has one edge (2a) next to the first fold. At least a second fold (5) is parallel with the first fold. A dispersion glue is used for sticking over the entire surface of the strip or in strips.
