Abstract
Method of attaching by crimping sheets of paper, especially a sheet of paper folded on itself, characterised in that it consists of producing on each edge two series of parallel tongues which interpenetrate in respect of thickness and are offset relative to each other so as jointly to provide an approximately continuous crimping, with the edges of these tongues, parallel to the edges of the sheets, resulting from a clean cut, whereas their end results from a tearing of the paper. <IMAGE>
