Abstract

On letter with copy matrix, perfected, that being of the type that is materialized from two overlapping sheets wound in coil and provided with two side alignments of holes in which connect the means of dragging office machines, the holes being parallel to internal tear lines and the bands affected by transverse tear or precut lines that determine detachable units that are provided with bending signals, essentially characterized in that one of both sheets, preferably the upper one, has one of the zones that defines the fold line a rectangular opening near one of its corners that is covered, by the side where data and text are inscribed, with a transparent sheet while in the other area and in the part where the opening is superimposed. Provides a marked area for the registration of the recipient, the upper sheet being affected by s tear or precut lines near or parallel to the tear or precut lines conventionally provided in the coil, determining strips in which gluing points are located, which are also repeated in parallel alignments provided on both sides of the lines cross-sectional pre-cut, by means of contact of some points with the opposites closing the envelope when both parts overlap, the envelope of which is tear off at either end by the pre-cut or tear lines provided behind the gluing points.
