Description

[Detailed explanation of the idea] The present invention relates to a glue applicator for printing and the like.

In offset printing, gum arabic liquid is commonly used as an image protection film for printing plates.

Usually, a 15% to 20% aqueous solution of gum arabic is prepared and applied with a sponge or cloth.

However, it is a criminal offense to create an aqueous solution of gum arabic during work, so the reality is that the aqueous solution is purchased and used.

For this reason, from the perspective of the supplier of the aqueous gum arabic solution, it must be transported by weight, and from the perspective of the user, space is required for storage.

Also, when using this aqueous solution, it was quite time-consuming because the appropriate amount was poured into a dish or the like and the solution was adsorbed onto a sponge or the like.

Therefore, in the present invention, we propose a gluing tool that can be made extremely lightweight and compact without the need to prepare an aqueous solution, is convenient for transportation and storage, is easy to use, and can perform an efficient gluing action. The method is characterized in that a sponge formed into an appropriate shape and size is impregnated with an arbitrary amount of water-soluble glue and dried.

The embodiment shown in the drawings will be described below. Reference numeral 1 is a sponge constructed into a size and shape convenient for use.

A water-soluble glue material such as gum arabic powder 2 is applied to the sponge 1.
2. Impregnate with...

This impregnation method involves passing air through which the gum arabic powder 2 is mixed into the sponge 1, allowing some of the gum arabic powder to accumulate, or reducing the pressure inside the sponge 1, and in that state, adding the gum arabic powder 2, 2. Further, dissolve gum arabic powder in water, immerse the sponge 1 in the aqueous solution, and impregnate it with the aqueous solution by expanding and contracting an appropriate number of times.
Next, by drying the sponge 1, the sizing is allowed to accumulate in the fiber gaps within the sponge 1, or any other suitable method may be used.

It is preferable that the adhesive is accumulated evenly within the sponge 1, but there is no difference if it is unevenly distributed.

Next, to explain how to use it, after soaking the above item in water and impregnating it with ice, when the sponge 1 is rubbed or pressed, the water impregnated in the sponge 1 comes into contact with the gum arabic powder 2, and it is immediately glued. to become

At the place where the gum arabic powder 2 has gelatinized, the printing plate surface is slightly
Press down and wipe away.

At this time, the gum arabic liquid oozes out onto the surface of the sponge 1, and adheres to and adheres to the printing plate surface.

By repeating this operation, if the gum arabic liquid no longer oozes out, a new sponge is used, and the used sponge is used for other purposes such as wiping.

Even if the sponge 1 is stopped and dried while the gum arabic remains in the sponge 1, it can be used again by soaking it in water.

According to the present invention as described above, a sponge formed into an appropriate shape and size is impregnated with an arbitrary amount of water-soluble glue and dried, so it can be formed into an extremely small and lightweight structure, which is convenient for transportation and storage. It can be used simply by soaking it in water, can be used without applying any liquid, can be used for gluing efficiently, and can be used not only for printing but also for other purposes, and has a wide range of uses.
