The invention concerns a device used for the formation of a thumb index in the side of a predetermined insert (4) of one or more sheets included in a volume (1). In order to simplify the formation of a thumb index, a base (15) extending into a space formed between the insert and associated identifying sheet (7) defining the bottom of the thumb index comprises a first stop (16) included in the base to support one main side of the insert, a pressure device (17) with which the insert is clamped to against the first stop, a second stop (25) included in the base to support one main side of the identifying sheet, a cutting unit (10) exhibiting principally a circular cutting head (11) that at its free end pointing towards the insert has a cutting edge (12) and which cutting edge can rotate around and move along an axis (14) towards the clamped insert, a means (18) of receiving the rotating cutting head included in the base after it passes through the insert. |
