Description

[Detailed Description of the Invention] This invention relates to a device for pasting a thin layer of gold leaf on the opening of an envelope.

Today, envelopes with a thin layer of gold leaf pasted around the edges are widely used to send wedding invitations.

By the way, in order to paste the gold leaf, as shown in Fig. 6, a large number of sheets of envelope paper 30 (paper with unfolded envelopes) are made with sloped edges, and are tightened from above and below using a tightening frame. After carving the sloping surface with a plane to make it smooth, glue was applied to the entire surface, and gold leaf was pasted on top.

However, this method requires a lot of work and requires only a slight slope on the side of the opening, and the gold leaf is pasted on that slope, making the gold leaf extremely thin and difficult to notice. Furthermore, because glue was used, product deterioration such as discoloration due to changes in humidity and temperature was inevitable.

The main purpose of this invention is to eliminate the above-mentioned drawbacks by using a transfer machine that transfers metal foil deposited on a synthetic resin sheet by heat and pressure bonding.

If a transfer machine is used here, the metal foil will be transferred to the straight part of the sealing opening of the envelope paper without any problem, but there is a risk that the metal foil will not be transferred sufficiently to the concave part at the edge of the sealing opening. There is.

The second purpose of this invention is to prevent the defective transfer in the recess at the end of the gutter as described above.

As shown in FIG. 1, the transfer machine has a pressing plate 20 disposed above a suppressing table 10, and the pressing plate 20 is attached to the tip of a pressing rod 21 that moves up and down by hydraulic pressure or the like. It has a built-in heater.

This idea is that after the above transfer, a convex strip 1 of a constant height is formed on both ends.
The main feature is that a mold table 1 having an inclined surface 11 with a slope 2 is mounted on a press table 10, and will be explained in more detail below based on the drawings.

FIG. 1 is a schematic diagram of the above-mentioned transfer machine used in this invention.

A mold stand 1 is mounted on a suppression stand 10.

The mold table 1 has an inclined surface 11 of a certain angle as shown in FIG.
As shown in FIG. 3, protrusions 12 of a constant height are provided on both ends of the inclined surface 11.

In addition, this mold table 1 has a suppression plate 20 so that the inclined surface is downward in the front.
It is installed directly below.

A transfer machine equipped with a die table 1 having such a shape is used in the following manner.

First, the envelope paper 30 has a shape as shown in FIG.

31, 32, 33, and 34 are the parts that should become the stanchions.

(2) With a large number of stacked envelope sheets 30, the inclined surface 4 is formed so that, for example, the opening 31 of the complete collection is exposed on the surface.

This inclined surface 4 has substantially the same slope as the inclined surface of the mold table 1.

0 Next, a large number of sheets of envelope paper stacked and tilted in this way are set on the mold base 1 in accordance with the slope of the inclined surface 11 of the mold base 1. are arranged horizontally on the inclined surface 11 of the mold base 1, and the grooves of the recesses 31' at the end of the gutter are arranged in parallel along the longitudinal direction of the protrusion 12. let

The half of the envelope paper 30 opposite to the opening 31 protrudes outside the mold table 1.

■Finally, the pressing plate 20 is strongly pressed against the inclined surface 4 to apply strong pressure to the metal foil film A placed on the inclined surface 4, and the metal foil (gold leaf) is transferred to the fencing opening 31 in a thin line. be.

The following steps (■■■) are one step, and by repeating this step four times, the gold leaf can be transferred to the cap body.

As can be seen from the above method of use, by applying the protrusions 12 to the recesses 31', 32', 33', and 34' at the ends of the gutter, the entire inclined surface 4 becomes horizontal.

Further, the pressure when the pressing plate 20 is pressed against the pressing table 10 is quite strong, and if metal or wood is used for the molding table 1, the pressing plate 20 will be damaged quickly.

Therefore, it is preferable to place a cushioning material 15 such as rubber on the mold stand 1, and then place the envelope paper 30 on top of it.

As mentioned above, since this invention uses a transfer machine, it is possible to transfer metal foil to the sealing openings of multiple sheets of envelope paper at the same time, significantly improving work efficiency compared to conventional manual methods. Can be done.

Moreover, if a transfer machine is simply used, there is a risk that transfer defects may occur due to the recesses at the edges of the envelope paper, but with this invention, protrusions are provided at both ends of the slope of the mold table, so this problem can be avoided. If you align the groove-like strands of the concave part at the end of the gate,
When strong pressure is applied by the transfer machine, the concave part at the end of the seal opening is pushed up and floated by the protrusion relative to the straight part of the seal opening, and both the straight part and the concave part of the seal opening are exposed to the transfer machine. The metal foil is flat and flush with the pressing plate 20, so that the metal foil is beautifully transferred even to the concave portions at the ends of the stitches.
