Abstract

Set of continuous documents, of the type consisting of several bands or sheets of continuous paper superimposed, all of them appropriately preprinted, of which the intermediate ones are letters or documents and the external ones, upper and lower, appropriately glued, make up the envelope of shipping, counting each band with a plurality of trailing holes disposed at the longitudinal edges and whose holes correspond to each other when the bands are superimposed, as well as another series of perforations in the transverse and longitudinal directions that define the height and width of each unit. On forming, essentially characterized in that the intermediate bands constituting the inserted documents have been subjected to a pouring operation that causes the elimination of transverse tabs, equidistant from each other, leaving gaps slightly wider than the width determined by two adjoining or contiguous gluing lines, and to a deburring operation that causes the detachment of the right longitudinal margin, in such a way that the internal document is only joined to the envelope by the longitudinal gluing line of the left margin, that is, by the margin that must be torn when the envelope is opened and likewise, characterized in that in order to facilitate the extraction of the inserted documents, there have been placed notches or weakening on both sides of the envelope, whose notches are preferably semicircular in shape and centered at the midpoint of the perforation line that tears when opened the envelope, which notches are adhered to the tongue that comes off when opening the aforementioned envelope.
