Abstract
Improved clipboard, which is characterized by the fact that present in its rectilinear branches, both those that define the upper and lower plane in its support on the paper, a matching transverse inflections, obtained by die-cutting or other system appropriate to the material and constitution of the paper clips, which are alternately applied on both sides of the piece and determine the adoption by these branches of a sinuous profile whose undulations, while increasing the grip coefficient by increasing the useful contact surface with the paper without this has an impact on the length of the paper clips, they are constituted by their inclined, concave or convex sections, opposed to the mouth of the former, in as many stops or brakes that are antagonistic to any force tending to slide the subject paper towards said mouth.
