Abstract

La présente invention concerne une perforatrice comportant un socle (10), au moins deux unités de perforation (20) à distance réglable, ainsi qu'un levier de pression (18) pivotant ou mobile sur le socle (10) pour assurer le déplacement des poinçons (56) disposés dans les unités de perforation (20). Pour pouvoir régler de manière simple et stable une pluralité d'écartements entre les perforations rencontrés habituellement dans la pratique, le socle contient un évidement (22) qui s'étend sur la longueur de fonctionnement de la perforatrice et dont le bord est ouvert vers le haut; cet évidement comporte un support de règle graduée (24) tournant autour de son axe longitudinal et présentant plusieurs échelles (24') visibles à travers l'ouverture du bord en différentes positions de rotation. Le porte-règle graduée (24) a la forme adéquate d'une barre ronde qui peut être verrouillée sur le socle (10) dans des positions de rotation prédéterminées.
