<p>The use of a re-usable contact adhesive or gum strip (1) is based on the attachment of the latter on a briston board (2) or similar laminate, to form a binding folder for any type of documents, prior insertion and pressing of those documents or sheets (4) to bind them against the spine which constitutes the surface of the adhesive or contact gum strip. These bound sheets or documents may be freed and reattached as many times as desired, without the intersention of mechanical elements, or damage to the documents. The binding system which defines the new referred use, provides great cold adhesion strength, versus the traditional systems which require heat fusion gums which have been previously heated by means of a machine or apparatus. <IMAGE></p> |
