Abstract
An improved file for punched cards, constituted by a metallic parallelepiped box with top cover, and whose box has the front longitudinal side folding. The bottom of the box presents a series of parallel transverse rods that constitute the sliding and guiding rails of the lower teeth of the chips. Below the rods there is a suede fabric that decreases the wear by friction of the tops of the toothing of the chips. (Machine-translation by Google Translate, not legally binding)
