Abstract

A module for postal transmission, particularly for confidential information such as bank statements and the like, according to the invention has at least four sections (13, 15, 17, 19; 313, 315, etc.) defined by parallel fold lines (7, 9, 11; 331, 332, etc.) for repeated folding; on one of the external sections (13; 313) of the module, in the fully-folded configuration, a window (F, F1) is provided for the address; the useful face of these sections is surrounded by a perimetrical strip for permanent sealing (23A, 23B, 23C; 623) to assure the inviolability of said face, while on the reverse side of it a non-permanent glueing (25B, 25C; 125B, 125C, etc.) is provided. With respect to the known cross-folding modules, the module of the invention has a larger useful surface available, assures a higher production rate and is more easily handled.

Dependent claims

A postal module, of the foldable and sealable type, separable from a continuous strip of modules suitable to be passed through a printer and then through a cutting unit in which individual modules are separated from the strip comprising:

a sheet having longitudinal and transverse axes of symmetry and including at least four substantially equal sections delimited by corresponding, preformed, parallel fold lines, said sections having a front face, usable for reporting confidential information, and back face,
one of said fold lines corresponding to the transverse axis of symmetry of said sheet and facilitating a first fold in which the front faces of said sections are disposable adjacent each other, the section delimited by one end of the sheet and the closest fold line parallel to it being provided with a window for visualizing an address correspondingly printed on the front face of a symmetrically disposed section delimited by an opposite end of the sheet and the closet fold line,
the remaining fold lines facilitating at least one further fold of the sheet in which the back faces of two adjacent sections are disposed adjacent to each other, the section with said window being kept visible on the folded sheet;
permanent sealing means provided on a perimetrical band of said face usable for reporting information for securing the inviolability thereof;
non-permanent glueing means provided on the back face of the sections to be disposed against each other so as to allow opening of the sheet for control;
and tearing means provided along said perimetrical band for complete opening of the sheet following its mailing and receipt.

Postal modules carried contiguously by a continuous strip adapted to be passed in one direction successively through automatic machinery including a printing means, a cutting means, a folding means and a sealing means, said postal modules each comprising:

first and second ends, and sides extending between said ends in said one direction,
a front face adapted to display information printed thereon by said printing means and a back face,
a predetermined length adapted to be cut from said strip by said cutting means,
a first axis of symmetry parallel to said one direction and a second axis of symmetry disposed transversely of said first axis,
a first preformed fold line formed at said second axis and at least one additional preformed fold line formed equidistantly between said first fold line and each of said first and second ends, whereby said fold lines delimit therebetween at least four substantially equal sections, one of said sections between one of said first or second ends and the fold line closest thereto including a window for viewing an address printed by said printing means on the section located between the other of said first or second ends and the fold line located closest thereto, said first fold line facilitating a first fold of said module by said folding means after said module has been cut from said strip in which the front faces of said sections are disposed adjacent each other, and said additional fold lines facilitating at least one further fold of said folded module by said folding means in which the back faces of two adjacent sections are disposed adjacent to each other,
permanent sealing means disposed in a perimetrical band about said front face for sealing facing adjacent sections by said sealing means after said first fold is carried out by said folding means,
non-permanent glueing means provided in a perimetrical band on the back face of said two adjacent sections whereby said two adjacent sections may be opened after being sealed by said sealing means,
and tearing means provided along said perimetrical band inwardly of said sides and the included end for completely opening said module following its mailing and receipt.
