摘要
Universal binding element for binding loose documents in a file, characterised in that it principally consists in an inner cover formed of a first part (2) that is intended for forming a front sheet; a second part (3) that is intended for forming a back sheet; and a third part (4) that is intended for forming a spine, which includes adhesive means (5) which are formed of glue (9, 10, 23) meltable under the influence of heat and which, when heated and subsequently cooled off can provide for an adhesive connection on both the inside (6) and the outside (7) of the formed spine.
