Abstract
Normalized adaptive punch, composed of a hollow base, equipped with a lower cover, through which the small paper cutouts eliminated in the formation of the holes are removed, and actuated by a fork lever, articulated at its ends and featuring a bar transverse joint of the lateral arms and acting on the heads of the perforating elements, characterized by presenting a plurality of these elements, formed by as many parallelepiped pieces, with a lower flange horizontally projected forward, which serves as a guide for the introduction of the paper in the corresponding groove inside which each perforating or cutting element descends, as its upper head is pushed by the descent of the aforementioned transverse bar, all of these drilling units being slidably fitted on the outer upper face of the base body, for what has been foreseen in the same a recess of the appropriate all of these features are associated units on an axis that facilitates the sliding of the same without losing the convenient alignment, so that they are arranged on the same base at variable distances, which can be appreciated on a fixed strip.
