Abstract
A form of perforation of the sheets intended to be part of files, books or other couplings, so that they are likely to be easily separated from the set formed by the plurality thereof, characterized essentially by the fact that the line of holes made in each sheet in the suitable place for the separation does not reach the opposite edges of the sheet, between the said line of perforations and said edges remaining free portions of all perforations that prevent the involuntary initiation of the tearing of the sheets when turning.
