Method for the realization of binding elements Method for the realization of binding elements, characterised in that one starts from a synthetic tube (4); the lengthwise cutting of this tube (4); the feeding through a mould (6) of the cut tube (4) in order to obtain a cylindrical element (7) with overlapping edges (8-9); the heating of the thus obtained cylindrical element (7) to fix it in the latter shape; the reshaping of the cylindrical element (7) to a flat strip (13); the making in this strip (13) of teeth (3) and the eventual release of the above mentioned flat strip (13), so that the latter automatically returns to the above mentioned fixed condition.
