摘要

Double set of documentation of commercial correspondence that being of the type of those that are constituted by at least three paper bands superimposed the interior of which functions as a letter, while the two external ones form the envelope by means of peripheral lines of gluing that do not affect the inner band by virtue of the smaller width that it presents in the area defined between its ends, which are of equal width as the formative bands of the envelope, existing, tear lines to separate shipping units to different recipients, essentially, is characterized in that each double set is transformable into two shipping units, by tearing and dividing the primitive unit through central weakening line according to its transverse axis, and separation, also by tearing, of each extreme marginal zones belonging to each one of the obtained charts, whose marginal zones have drilling holes for the trawl set of continuous bands of the paper during the manufacturing process of the letters-envelope having been foreseen that the opening of the envelope and extraction of the letter is effected by detachment, by tearing another extreme marginal zone adjacent to that eliminated prior to the sending of the letter- on.
