no. 2 Embodiment approach

[0150] 2. The second embodiment ( Figure 14 ~ Figure 17 )

[0151] Figure 14 It is a figure showing the surface (the side on which the addressee's name is printed) of the envelope paper 200 used in this embodiment, figure 2 It is a figure which shows the back side. The envelope paper 200 is a rectangular paper in which three paper pieces, namely a first paper piece 201 , a second paper piece 202 , and a third paper piece 203 , are connected by creases.

[0152] Such as Figure 14 As shown, the surface of the first sheet of paper 201 is equivalent to the back of the envelope, and the sender's name, address, etc. are printed. In addition, two perforation lines 204 are formed on the first sheet 201 from the long side parallel to the crease to both edges in the width direction. What is necessary is just to peel off the center part of the 1st paper sheet 201 along this perforation line 204, when opening the sealed envelope. The surface of the second sheet 202 corresponds t...

Abstract

In a sealed letter producing device which folds and seals, with a content, an envelope sheet on which pressure-sensitive adhesives are provided, sealing with pressure rollers smaller than in conventional rollers is achieved. Pressure-sensitive adhesives 106 are provided in both edge portions in the width direction of an envelope sheet 100, and remoistening paste 107 is provided inwardly of both edge portions. The remoistening paste is moistened when the envelope sheet wrapping a content is bent and formed into an envelope 50, the entire surface of the envelope is pressurized by low-pressure rollers and adhered with the remoistening paste, and further only both edge portions of the envelope 50 are pressurized by an upper and lower set and a left and right pair of the pressure rollers 80, 80 having a small width to adhere the pressure-sensitive adhesive 106. High pressure required for adhesion of the pressure-sensitive adhesives is only necessary in both edge portions of the envelope, and therefore small pressure rollers 80 will suffice.

Description

technical field [0001] The present invention relates to a sealed letter making device capable of printing envelope paper and content paper with a simple structure, and enclosing sealed content in the envelope by folding the envelope paper, and Envelope paper (paper folded into envelopes) suitable for such devices. Background technique [0002] Patent Document 1 below discloses an invention related to a method of producing a sealed letter by folding it in three. exist Figure 31 and Figure 32 The middle represents envelope paper substantially the same as the sealed letter form used in this invention. Such as Figure 31 As shown, the envelope paper 300 has a structure in which three paper sheets, the upper paper sheet 301 , the middle paper sheet 302 , and the lower paper sheet 303 , are connected by perforated lines. The addressee's name is recorded on the surface of the upper paper sheet 301 , and the content is recorded on the surfaces of the middle paper sheet 302 and ...
