Description

[Detailed Description of the Invention] The present invention relates to an apparatus for applying an adhesive substance to an object to be coated, and is particularly characterized in that unevenness can be easily formed at required intervals on a layered coating surface.

The object 1 to be coated is continuously fed and supported by a table 3 at a position where the adhesive substance 2 is applied. The knife 4 is positioned above the table 3 so as to sandwich the object 1 to be coated, extends substantially perpendicularly to the object to be coated, and supplies the adhesive substance 2 to the intersection of the knife and the object to be coated. I'm accumulating it. When the object 1 to be coated is moved in the direction of the arrow in this state, the adhesive substance is leveled with a knife 4 into a layer 5 of a constant thickness and applied to the object.

The rotor 6 has a circumferential portion 7 with the same radius on its outer circumferential surface.
and a raised part 8 having a radius larger than the circumferential part, and is located below the table 3 on the opposite side from the adjusting knife 4. The outer circumferential surface of the rotor 6 may be brought into direct contact with the object 1 to be coated by looking into the hole 9 of the table 3 (FIG. 1), or may be brought into indirect contact via the driven body 10. Good (Figure 2). The flat plate portion 11 of the driven body 10 contacts the outer peripheral surface of the rotor 6, and the upright portion 12 penetrates through the hole 9 of the table 3 and contacts the object 1 to be coated.

As the rotor 6 rotates, while its circumferential portion 7 is in contact with the object to be coated, the distance from the tip of the knife 4 is constant, the thickness of the coating layer 5 is constant, and the raised portion 8 is formed. Upon direct or indirect contact, the object 1 to be coated is lifted in the direction of the knife 4 and the distance between them narrows, and the rotation of the rotor creates a depression 1 in the coating layer 5.
3 are formed at equal intervals.

The recesses 13 in the coating layer may be made one step lower (Fig. 3), sloped into a concave curved surface (Fig. 4), or sloped into a convex curved surface (Fig. 5).
), it may be formed into an appropriate shape and raised on the outer circumferential surface of the rotor according to the shape. Note that the protuberance is not limited to one location, but may be provided in a plurality of locations.

The coating layer of the adhesive substance and the object to be coated are cut at the recesses 13 of the coating layer using cutting means of a fixed blade 14 and a movable blade 15 (the fixed blade and the movable blade may be reversed, or both may be movable blades). In this case, the adhesive substance does not adhere to the cutting means, and continuous cutting can be performed smoothly. In addition, the adhesive layer becomes thinner at the cut surface, preventing adhesive substances from flowing out from the cut surface, and when stacked with release paper, they do not adhere to each other and retain their commercial value well. can.

Application examples of the products obtained with this device include cockroach catchers, poultices, poultices, patches, stickers, and protective papers. To explain about cockroach catching tools, there are various ones on the market.One example is the bottom wall 1 of the box body 16 that is assembled into a tunnel shape.
7 is provided with an adhesive layer 18 and covered with a release paper 19. The manufacturing method is to apply the adhesive layer 18 to a release paper 19 so that there are depressions at predetermined intervals, and to cut the bottom wall of the box body along the depressions.
Glue it to 7 and remove the release paper, leaving behind the adhesive layer.
If the cut end surfaces of the adhesive layer 18 and release paper 19 are located inside the end surface of the bottom wall 17, even if some of the adhesive on the cut end surface of the adhesive layer leaks out from the cut surface of the release paper, it will not reach the margin of the bottom wall. It is absorbed and does not flow out from the end face, and therefore, even when the deployed catching tools are stacked, they do not stick to each other. The cut ends of the adhesive layer 18 are formed into various shapes including those shown in FIGS. 8 to 10.

As described above, the present invention includes a knife 4 which is provided on one surface of a moving object 1 and is involved in applying the adhesive substance 2 in a layer to the surface, and a knife 4 which is provided on the other surface. The rotor is provided with a rotor 6 which is involved in changing the distance between the object to be coated and the knife, and the rotor has a circumferential portion 7 having the same radius on its outer circumferential surface and a raised portion 8 having a larger radius than the circumferential portion. The distance between the object to be coated and the knife is changed at the circumferential part and the raised part, the thickness of the coated layer is constant at the circumferential part, and the depression 13 is formed in the coated layer at a constant thickness at the raised part. Because the structure is simple, it is possible to easily form depressions at regular intervals, and by cutting the depressions with a cutting blade, sticky substances do not adhere to the cutting blade. Continuous cutting can be carried out smoothly, and the adhesive layer becomes thinner at the cut surfaces, thereby preventing adhesive substances from flowing out from the cut surfaces.
