Description

[Detailed Description of the Invention] (a) Industrial Application Field The present invention relates to an apparatus for manufacturing windowed envelopes, and in particular, it relates to a manufacturing device for envelopes with windows, and in particular, to produce envelopes that are horizontally folded in half by bursting one continuous paper for forming an envelope body. In connection with the sealing process of this envelope body, an insert piece burst from another continuous paper and pre-processed with information is enclosed in a non-adhesive state between the horizontal folds of the envelope body. The present invention relates to an apparatus for manufacturing envelopes with windows.

(b) Prior Art Conventional continuous envelopes consist of multiple continuous sheets of paper, e.g.
The continuous paper for the front layer, the continuous paper for the back layer, and at least one sheet of continuous paper for saddle stitching are stacked one on top of the other, and each envelope unit is adhesively sealed along its edges, and then each unit is A burst was generated in each envelope area to create a sealed envelope. However, in this conventional envelope, the exterior of the envelope body and the saddle binding piece on which information is to be processed are glued together, so a part of the finished envelope body must be opened. However, the inner saddle binding strip cannot be immediately removed, and the bag must be opened along at least three sides in order to view the information on the saddle binding strip. Further, in this conventional envelope, since an adhesive layer is provided on the saddle-stitch continuous paper to be subjected to information processing, thermal printing such as non-impact printing processing by a computer is not possible. Furthermore, since conventional envelopes burst after each continuous sheet is sealed, they are not suitable for envelopes that enclose a single-piece saddle-stitched piece in advance.

Furthermore, conventionally, the continuous paper for the front layer and the continuous paper for the back layer are adjusted so that their respective envelope body unit areas are aligned, and then the envelope body unit area between the two layers is filled with an insert that is not adhered to both layers. 2. Description of the Related Art Sealed envelopes configured to enclose paper are known, and manufacturing equipment therefor has also been provided. However, this sealed envelope manufacturing device requires at least three sheets of continuous paper and a means for supplying them, and the continuous paper for the front and back layers are fed out after being aligned for each envelope unit area. The device becomes complicated in that it requires adjustment means and timing means for inserting the insert paper in alignment with the envelope unit areas of both layers.

A series of continuous papers for forming insert paper, which have no adhesive layer at all and are subjected to computer printing processing, are prepared in advance, and the former continuous paper is burst to form an envelope body folded in two horizontally. In connection with the sealing process of this envelope body, after bursting the latter continuous paper,
This is a manufacturing device for enclosing the envelope in a state in which it is not glued between the horizontal folds of the envelope. According to this device, the insert paper, which has undergone intensive information processing using a high-speed computer such as a non-impact printing processing machine, can be immediately printed by opening one side of the envelope while leaving it free inside the envelope. It is possible to continuously and mechanically form sealed envelopes that are reliably sealed in a manner that allows them to be taken out, and it can be said that this type of device is extremely effective.
