Then, if the envelope sheet Pe is sent to the adhesive attaching section 3 and the path sensor 31 detects the leading end of the envelope sheet Pe, the feed roller mechanism 27 is set after a lapse of a set time.
Stop d and 32. As a result, the leading end of the envelope paper Pe is positioned on the pedestal 36 in the front adhesive applying mechanism 5 and stopped. Thereafter, the front adhesive applying mechanism 5
Is operated to provide the front adhesive portion Jf on the envelope paper Pe (see FIG. 1). Next, the feed roller mechanism 32 is operated to transfer the envelope paper Pe forward. Then, when the path sensor 54 detects the leading edge of the envelope sheet Pe, the feed roller mechanism 32 is stopped after the set time has elapsed. As a result, the leading end of the envelope paper Pe is positioned on the pedestals 36... Of the left adhesive applying mechanism 6 and the right adhesive applying mechanism 7 and stopped. Thereafter, the left adhesive applying mechanism 6 and the right adhesive applying mechanism 7 are operated synchronously to provide the left adhesive Jp and the right adhesive Jq on the envelope paper Pe, respectively (see FIG. 1).

In this case, the attaching operation by the left adhesive applying mechanism 6 is as follows. In addition, the other adhesive bonding mechanism 5
And 7 are basically the same as the left adhesive applying mechanism 6.

First, the adhesive dispenser 15 at the home position indicated by the solid line in FIG.
If it is moved to the right in the middle, the regulating roller 46
8, the adhesive supply unit 45 moves to the other end of the guide rail 47 while being separated from the envelope paper Pe. Adhesive applicator 1 in this state
5 is indicated by reference numeral 15m. When the regulating roller 46 comes off the other end of the guide rail 47, the regulating roller 46 is moved in the opposite direction, so that the regulating roller 46 is guided by the lower surface of the guide rail 47. The adhesive applicator 15 in this state is indicated by reference numeral 15n. At this time, the adhesive supply unit 45 supplies the envelope paper P
e, the tip of the double-sided tape supplied from the adhesive supply unit 45 is stuck to the envelope paper Pe,
In addition, since the double-sided tape moves while being pressed, the double-sided tape is attached to the envelope paper Pe according to the movement of the adhesive supply unit 45. Then, the adhesive supply section 45 is connected to the guide rail 47.
When it returns to one end and comes off the guide rail 47, the pressure on the adhesive supply section 45 is released, so the double-sided tape is cut and the bonding is completed, and the adhesive applicator 15 is returned to the home position. At this time, the switch 48 is pushed upward by the regulating roller 46. As a result, the left adhesive portion Jp is provided on the upper surface (back surface Pei) of the envelope paper Pe.

Next, the suction transport unit 49 is operated to feed the envelope paper Pe into the paper folding unit 4. At this time, as shown in FIG. 6, the gate mechanism 71 shuts off the transport line R, and the gate mechanism 88 is located above and the transport line R

... lightly contact the envelope paper Pe. As a result, the envelope paper Pe is conveyed while being sandwiched between the conveyor 66 and the drive rollers 82, and the drive rollers 82 are prevented from contacting the front adhesive portion Jf. When the path sensor 73 detects the leading end of the envelope paper Pe, after the set time has elapsed, the press board 81 is raised to the first release position Ym, and the rotation of the conveyors 66 is stopped. The set time in this case is set to the time until the leading end of the envelope paper Pe contacts the gate mechanism 71. In addition,
After the press board 81 has been raised to the first release position Ym, if the rotation of the conveyors 66 is continued for a predetermined time, the leading end of the envelope paper Pe contacts the gate mechanism 71 and the skew is corrected. Also, the rear end of the envelope paper Pe (one end P
es) is a position slightly past the first step portion 68f of the guide plate 68. Thereby, the envelope sheet Pe is positioned at the envelope sheet setting position Xe.

Specifically, one document sheet Pd is taken out by the pickup roller 22d, and the document sheet Pd
Is the first-stage feed roller mechanism 24d, the first-stage guideline 2
3d, the second-stage feed roller mechanism 27d, and the second-stage guide line 26d are sent to the adhesive adhering section 3. In addition,
The path sensor 25d detects the leading end of the sent document paper Pd, and after a lapse of a set time, the subsequent feed roller mechanism 27d.
Is rotated to correct the skew on the document paper Pd in the same manner as on the envelope paper Pe. Further, in the adhesive application section 3, the suction conveyance section 49 operates, and the document paper Pd is sent to the paper folding section 4. At this time, the path sensor 54
Detects the leading end of the document paper Pd, the press board 81 is moved to the set position Ys indicated by a virtual line in FIG.
To bring the drive rollers 82 into contact with the document paper Pd. As a result, the document paper Pd is driven by the drive rollers 82.
Is transferred by the rotation of. The transport conveyors 66 are stopped. When the second set time has elapsed after the detection by the path sensor 54, the press board 81 is raised to stop the rotation of the drive rollers 82. The second set time sets the time until the leading edge of the document paper Pd contacts the gate mechanism 88. As a result, the skew of the document sheet Pd is corrected similarly to the above-described envelope sheet Pe, and the document sheets Pd are positioned at the document sheet setting position Xd on the envelope sheet Pe. When the number of document sheets Pd is plural, the same operation is repeated.

The envelope sheet P in the sheet folding section 4
When the positioning of e and the document paper Pd is completed, the press boards 81 and 86 are lowered to the lowermost press position Yp as shown in FIG. Thereby, the driving roller 82

Displace downward. Therefore, the envelope paper Pe and the document paper Pd are bent at substantially right angles at the positions of the first folded portion K1 and the second folded portion K2.

Next, as shown in FIG. 9, only one press board 81 is raised to the upper limit second release position Yua. Then, the bending arm mechanisms 74p and 74q located on the rear side in the transport direction are rotationally displaced, and the rotating rollers 74pr and 74qr at the leading end portions are brought into contact with the left and right edges on the rear side in the transport direction of the envelope paper Pe. With the envelope paper P
e and the document paper Pd are folded back from a substantially right angle position to an acute angle, and in this state, the press board 81 is lowered again to the press position Yp. As a result, the envelope paper Pe is completely folded back at the first folding section K1, and bonding is performed.

Similarly, only the other press board 86 is raised to the upper limit second release position Yub. Then, the bending arm mechanism 75 located on the front side in the transport direction
p, 75q are rotated and displaced, and the rotating roller 75p at the tip end is rotated.
r and 75qr are brought into contact with the left and right edges of the envelope paper Pe on the front side in the transport direction, so that the envelope paper Pe and the document paper Pd are folded back from a substantially right angle position to an acute angle, and the press board 86 is folded in this state. Then, it is lowered again to the press position Yp. As a result, the envelope sheet Pe is completely folded at the second folding section K2, and bonding is performed.
On the other hand, in this state, after the press board 81 alone is further raised to the upper limit second release position Yua and then lowered again to the press position Yp, the other end P of the envelope paper Pe is obtained.
The et side is pressed, and in particular, the front bonding portion Jf is bonded. Therefore, the sealed letter F of FIG. 14 is created.

Next, as shown in FIG. 10, one press board 81 is at the first release position Ym, and the other press board 86 is at the set position Ys where the idle rollers 87... Then, the transport conveyor 66,..., And the feed roller mechanism 69 and the press roller mechanism 70 are operated. As a result, the gate mechanism 71 opens the transport line R, and the sealed letter F is sent out forward, is completely pressed by the press roller mechanism 70, and is then discharged from the automatic letter-seal creating device 1.
