Abstract
Improved demountable reel, which is constituted essentially by two twin discs, provided with a series of opposite holes, equidistant from the center of said disks, through which they are joined together by means of slightly curved plates, provided with fins in its ends, by which they fit into those holes, bending over the discs to strengthen them, thus preventing the recoil of these and constituting the set of the sheets the core of the reel.
