Research of durability of Braille formed in paper
Keywords:Braille, durability of Braille dots, properties of paper.
In the present work, the change of the height of a Braille dot is studied by imitating the usage process of a Braille. An analysis of the change of a Braille dot under a load action that occurs (or may occur) during storage in pallets, stocking, transportation, as well as actual use is performed. A simple Braille strengthening technology is suggested.
