Abstract

PROBLEM TO BE SOLVED: To prevent a screen mesh and a sheet from being torn when a central part of the screen mesh is cut out along an edge part of the sheet by a method wherein the screen meshes in which directions of threads forming the mesh are different from each other are held with a screen frame material under a state wherein at least two screen meshes are piled on each other. SOLUTION: Screen meshes 2.3 braided with threads composed of polyester synthetic resin are tensed up with each other under a state of being tensed vertically and horizontally inside a screen frame material 1. The screen meshes 2.3 are superimposed on each other so that directions of the threads forming the mesh are different from each other. A sheet 4 wherein a character, a pattern, etc., are drawn by through holes is stuck to a central part of the screen meshes 2.3 via an adhesive layer 5 being a sticking margin. Thereby, when the central part of the screen meshes 2.3 are cut out, the screen meshes 2.3 can be prevented from being torn by tensile force to the frame materials 1B-1D.

The screen mesh located inside the sticking shiro of the sheet is cut out along the edge of the sheet.

[0003]

By the way, in the combination mask configured as described above, the screen mesh is held in a state of being pulled in four directions (vertical left and right) by the frame material of the four sides constituting the plate frame material. Therefore, when the central portion of the screen mesh is cut out along the edge of the sheet, the screen mesh may be torn due to the tensile force applied to the frame material. May also tear the sheet,
As a result, there has been a problem that economic loss increases.

The present invention has been made in view of the above circumstances, and it is possible to prevent the screen mesh and the sheet from tearing when the central portion of the screen mesh is cut out along the edge of the sheet. The purpose is to provide a combination mask with excellent economic efficiency.

[0005]

In order to achieve the above object, in the first invention, a screen mesh held in a tensioned state inside a rectangular plate frame material and a center of the screen mesh are provided. Which is a combination mask cut out along an edge of the sheet, wherein the screen mesh is attached to the sheet and has a sheet to be a printing surface, and the screen mesh is located inside the sticking white of the sheet. The screen mesh is characterized in that at least two screen meshes are held by the plate frame material in a state of being superposed on each other.

In a second aspect of the invention, the screen meshes are overlapped so that the yarns forming the meshes have different directions.

The present invention having the above-described structure has the following operations. That is, in the combination mask shown in the first invention, at least 2
Since the screen meshes are held by the plate frame material in a stacked state, when the central part of the screen mesh is cut out along the edge of the sheet, the screen mesh is torn by the tensile force to the frame material. This prevents the screen mesh and the sheet from being wasted as in the conventional case. Further, when the central portion of the screen mesh is cut out, if the screen meshes are sequentially cut out one by one, in the step of cutting out the screen mesh, the tensile force on the frame material is concentrated at the cutout portion of the screen mesh. It is possible to prevent the breakage of the screen mesh more effectively without causing any damage.

In the combination mask according to the second aspect of the present invention, the plurality of screen meshes are stacked so that the directions of the yarns forming the meshes are different from each other, so that the central portion of the screen mesh is aligned with the edge of the sheet. When cutting out, when the screen mesh is about to tear due to the tensile force applied to the frame material, the tearing direction will be different depending on the screen mesh, which can effectively prevent the screen mesh from tearing. .
