Abstract

(57) [Summary] [PROBLEMS] To provide a single-layered sheet in which corrugated sheets are interleaved without being fitted in a wave and reducing the thickness. SOLUTION: By using a corrugated plate 1 and a large corrugated plate 2 having different wavelengths of corrugated plates 4, even if the corrugated plates 4 are bonded to each other, the wavelength does not tune, so that the waves do not get stuck and the thickness is reduced. You can insert single-stage corrugated sheets without any paper.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an interleaf sheet which has a thickness increased by interleaving (attaching) one step (corrugated paperboard in which a flat plate is stuck to only one side of a corrugated sheet).

[0002]

2. Description of the Related Art In a conventional interleaf sheet, a flat surface serving as a liner is bonded to the corrugated surface without bonding the corrugated plates to each other. In the case where the corrugated sheet surfaces are bonded together, a flat plate is sandwiched between the corrugated sheets so as to prevent the corrugations from being fitted together, or a two-stage structure (both sides of the corrugated sheet). Corrugated paper with a flat plate attached to the corrugated paper) and a single-stage corrugated sheet.

[0003]

The interleaving paper sheet with the flat surface bonded to the corrugated surface has a problem in that one surface becomes a corrugated plate, so that a clear printed surface is not obtained, and dust easily adheres. was there. Further, in the case of a structure in which a flat plate is sandwiched between corrugated plates or a structure in which both stages and one stage are interleaved, it is necessary to prepare an extra flat plate. In the present invention, in order to solve the problems of the prior art, there is provided an interleaf single-stage which can interleave corrugated surfaces without using an extra flat plate to fit the corrugations of the corrugated plate. Aim.

[0004]

[Means for Solving the Problems] By not matching the wavelengths (the size of the crest width) of the corrugated sheets of the single step to be bonded, the crests of the crests sometimes collide with each other, so that the creases do not fit into each other and the thickness is reduced. You can insert it without letting it go.

BEST MODE FOR CARRYING OUT THE INVENTION The product of the present invention may be manufactured using paper as a material, and thick paper may be used. However, a packaging material having a cushioning function, such as a cushioning packaging sheet made of artificial resin and having air bubbles, may be used. It is preferable to use thin paper having no stiffness as the material because it is used in a rolled shape, and the edge of the corrugated sheet in the ridge direction is the side, that is, the side.

In FIG. 1 which is a perspective view of a single-stage separation, two single-stage plates 3 having different wavelengths of a corrugated plate 4 are prepared, and the corrugated plates 4 are opposed to each other. Of the corrugated plates 4 having different wavelengths, the smaller wavelength plate is referred to as the small corrugated plate 1 and the longer wavelength plate is referred to as the large corrugated plate 2.
The interleaving paper between the corrugated sheets 4 may be applied by applying glue to the entire ridge of the wave, but it is preferable to apply the glue on a line extending in a direction perpendicular to the ridge of the wave. It is also possible to use a rail in which the glue is applied in a convex shape, but it is desirable to apply glue from a thin nozzle to apply it on a line. The interleaving paper of the flat plate 5 and the corrugated plate 4 forms the corrugated plate 4 In the process of performing, a conventional method may be used in which one side 3 is formed by applying glue with a glue roller in a state of being wound around a step rolling roller,
Further, similarly to the method of interleaving the corrugated sheets 4 described above, a method of extruding glue from a nozzle, applying glue on a line, and interleaving may be employed.

In FIG. 2 which is a perspective view of a single-stage interleaving paper, if the corrugated plates 4 of the single-stage 3 are joined together, the corrugated plates 4 are small corrugated plates 1 and large corrugated plates 2 having different wavelengths. If the valleys do not synchronize, they will not fit together, forming a collision portion 6 where the peaks of the corrugated sheet 4 collide with each other, and at the location of the collision portion 6, the corrugated plates 4 are interleaved, and the outer (top and bottom) surface is flat. 5 makes it difficult for dust to be attached. If printing is performed, the printed surface becomes clear. If the glued portion is on a line, the non-bonded area is large, so the whole sheet is easy to bend, and as a cushioning wrapping sheet. It becomes easy to handle.

In FIG. 3, which is a side view of the single-ply paper, when the state of the single-ply paper 3 is viewed from the side, the corrugated sheets 4 have different wavelengths, such as a small corrugated sheet 1 and a large corrugated sheet 2. Since the wavelengths are not synchronized, they do not get stuck, and they are bumped and glued at places where they hit each other, so that the corrugated sheets 4 of the single step 3 can be interleaved without reducing the thickness without sandwiching the flat plate 5 therebetween. As a result, the flat plate 5 is projected on both outer surfaces.

[0009]

By combining a small wave plate and a large wave plate having different wavelengths, the wavelengths of the wave plates are not tuned, so that the waves do not fit into each other. Even if a flat plate is not sandwiched between corrugated plates, it can be interleaved without reducing the thickness.
