A perforator for paper or similar thin sheets, comprising at least one punch (14) arranged on a movable limb whereby said punch cooperates in the direction of perforation with a second punch hole (16) arranged on a second limb (12), whereby the first limb (10) is movably mounted on said second limb. The invention is characterized in that at least one of the limbs (10,12) is embodied as an elastic hollow profiled section (20) which, when seen on the plane of the direction of perforation (S), has a rectangular shape, and at least the longer delimiting walls (22) of the hollow profiled section (20) are made of elastic material. |
