Description

DETAILED DESCRIPTION OF THE INVENTION The present invention has a structure in which a window is cut out in the address area on the surface of the envelope from a continuous roll of paper, which is the material for the pricks, and transparent paper such as cellophane, vinyl, or polypropylene is pasted to that area. This book describes a method for continuously manufacturing window-perforated envelopes, which speeds up the cutting process of envelope base paper (window cutting, edge cutting), as well as speeds up the pasting of transparent paper. The purpose is to improve the efficiency of manufacturing and significantly reduce product costs.The method of the present invention will be explained in detail below using an example of an apparatus shown in the drawings.

Winding m Window-cutting blade type (
4), and has an air intake hole and an air supply hole (5) connected to an air pump (not shown) on the inner surface of the blade mold, and transfers the air between the anvil roll (8) that receives the rotating part, and removes the window. Production envelope cutting length interval (stop) on the base paper (1) using the blade type 14)
This forms a window (9) as shown in Figure S. At this time, the base paper 0) has a suction effect on the inside surface of the window cutter mold 14) which acts as an intake hole and an air supply hole. The anvil roll (8) and the window cutting blade IJ 14 are in a chipped state.
) and the cutting is carried out quietly.

The cutout piece rotates with a cutter roll (nK) until the intake hole/air supply hole (5) connects from the intake path (a) to the air supply path (1), and is discharged at a predetermined position and sucked. It is discharged to a predetermined position by the suction gamma connected to the fan.Meanwhile, at regular intervals the base paper (υ) in the form of a window (9) passes through a set of gluing rollers installed on its transfer path. window(

(If υ is horizontal (advanced, it becomes republic).

A film-like transparent sheet made of vinyl, polypropylene, etc. is fed from the feeding roller device OAK to the seven rolls wrapped above the base paper (1), and then Attach the tip to the air intake hole and air supply hole (to) of the outside mtii of the pressure roll (to), which is provided to rotate in contact with the upper surface of the jI paper (phantom), and also clamp it to the connection with the feed roller (b). At the same time, feed the base paper (υ) onto the transparent sheet (
Rotating blade (to) and fixed blade (to) installed above and below the feeding path of (to)
Cut into transparent paper pieces of specified length by interlocking with the paper.

Apply 1 layer to the glue surface (2) around the window (-) of the base paper (υ) using a pressure roll.The air intake hole connected to the oart air pop (not shown) is an air intake hole and air supply hole of the pressure roll (2). Road (
) and the air supply path @ as it rotates, so after the air intake hole/air supply hole (A) reaches the base paper (1), the air intake hole/air supply hole (■) becomes the air supply path. (2), the absorbing action is released, and the transparent paper strips are sequentially and smoothly adhered to the upper surface of the window (9) with the pressure roll (to).

The base paper (1) with the transparent paper strips stuck to the windows (9) cut out at regular intervals in this way is enveloped by each roller of the roller set printing device @d installed at one to several locations in the transport path. Postal code frames and other appropriate printing are applied to the surface of the base paper at intervals of 1. Next, the base paper is passed through a cutting device installed in the transport path, and the base paper is stamped at regular intervals on both sides of the base paper (1). A chevron-shaped notch is formed. As an example, the die cutting device for this base paper (1) is protected by the applicant's rights (Patent No. 97).

In other words, the base paper (1) is passed between l pairs of feed rolls @ (2) provided in the transport path, and further spaced at intervals of circumferential length equal to the envelope forming length and cutting amount). The left and right tc ('Il-shaped blade types (to)) on the roller surface are attached, and each blade type is inwardly connected to the air supply path (to) and intake path connected to an air pump (not shown). A cutter roll (2) is provided with an intake hole and an air supply hole (to) and is provided so as to locally perform air intake and air supply during one rotation.

The blade m- of the cutter roll (2) and the anvil roll (2) are fed by feeding the base paper (1) through the anvil roll (2) which is provided to rotate together with the roll. ) and KN paper (υ) are pressed together, and ^-shaped notches (to) are cut out at intervals equal to the amount of molding on both sides of the base paper (1). While the continuous folding piece (2) is formed, the cutout piece rotates to a predetermined position while being sucked by the cutter roll.

The intake hole and air supply hole communicate with the air supply path, and when the air is discharged, it is collected at a predetermined place through the suction duct of Ka puller 77/.

A base paper with chevron-shaped notches am cut out on both sides at regular intervals (υ is a linear gluing device, i.e., the right of the applicant (Patent No. 81)
713//), the base paper is passed through the gluing device (gluing device) that applies glue from the gluing elastic cord C11lIK of the process/dress that rotates through the gluing tank (gluing tank) and the lower nozzle (gluing)'. After attaching the glue line in a straight line to (1), fold both sides of the base paper (1) inward through the folding #@ (to) of a known bag making machine. After polymerizing and adhering, the middle of the continuous folding pieces (1) and 2 is crossed by a cutting roll (B), and the bottom folding piece (B) is bent and pasted to sequentially and continuously manufacture the window-perforated side part. It is.

In the envelope manufacturing method of the present invention, the I''!-shaped notch formed on both sides of the JI paper (1) is divided into two parts: a chevron-shaped part and a C-shaped part. It is also possible to place the rollers on the left and right sides of the roll surface and make two cuts at the same time to make an N-shaped cut.In this case, the corners that are easily worn out can be removed.
Overall, the life of the blade can be extended to the maximum.

As explained above, the continuous manufacturing method of the window-perforated side part of the present invention not only allows the roll paper and transparent sheet of the envelope to be consistently and continuously fed by the feed roller device, but also enables the continuous manufacturing method of the window-perforated side part of the present invention. The various processes of cutting and pasting the transparent paper pieces to the punching section, cutting the base paper into shapes, printing, folding, and manufacturing envelopes are all carried out by roller rotation, so there is no need to stop the base paper and transparent paper. It is also possible to simultaneously speed up the production of window-perforated envelopes automatically and continuously with high efficiency compared to conventional methods that had difficulties in transporting transparent paper, cutting it to the appropriate size, and pasting it. However, since the processing means provided in the feeding path of the paper and transparent paper is a set of rotating rollers, there is no obstacle to their progress.

In particular, there is no risk of trouble or wrinkles occurring with film-like transparent paper (it has the characteristics of being able to significantly increase production speed, greatly reducing costs, and being able to provide inexpensive Km).
