Description

[Detailed Description of the Invention] The present invention relates to a pretreatment device for a core material used in manufacturing a stretchable lattice body.

In this specification, the stretchable lattice-like body A is shown in FIGS. 1 and 2, and is a rectangular shape in which glue margin pieces 2a and 2b are provided on the outside of the folds 1a and lb on both sides so as to be bendable. A large number of core materials 3 made of sheets of kraft paper or the like are provided, one side of the core material 3 is glued to one of the mounts 4, and the other side of the other adhesive material 2b is glued to the other side. A large number of sheets of the core material 3 are successively provided at regular intervals between two or more sheets of mount 5, and are normally compressed into a plate shape, but when expanded, the core material 3 is It is used to create a grid pattern.

Hereinafter, in this specification, the term "stretchable end-shaped body A" is as defined above.

The stretchable lattice body A (hereinafter simply referred to as the lattice body) is composed of the mount 4 and the core material 3 as described above, but the mount 4
It is not easy to adhere the core material 3 to the substrate in an orderly manner.

The state in which a large number of core materials 3 are adhered to the mount 4 in an orderly manner is the third state.
As shown in the figure, when bonding only one side of the glue margin piece 2b on one side of a large number of core materials 3 to a mount 4, a large number of core materials 3
The glue margin piece 2a on the other side is the glue margin piece 2a on one side of the adjacent core material 3.
b and the core material 3 is on the −・ side of the adhesive piece 2b.
must be polymerized by the width of the

Therefore, in order to manufacture the lattice-like body A, as described above, a device is required for arranging a large number of core materials 3 by shifting their positions by a distance corresponding to the width of the adhesive strip 2b on one side.

In addition, the core material 3 between the mounts 4 and 5 of the grid-like body A has folds 1a and 1.
Since it can be folded and folded freely through the lattice-like body A, the third part is provided with pre-folding lines 1a and 1b, as well as the adhesive pieces 2a and 2b. In order to make it easier to bend 2b in different Jj directions, a "fold crease" is provided in advance.

Therefore, as a pretreatment for adhering the core material 3 to the mount 4, in addition to arranging the core material 3 as described above, in order to make it easier to adhere the core material 3 to the mounts 4 and 5, the core material 3 with the "crease texture-J" It needs to be stretched horizontally.

The main idea is based on the above points, and its purpose is to write tJ? The eyes and
When adhering the core material that has been given a crease pattern,
As pre-treatment, stretching is performed in conjunction with positioning of the core material.

The details of the present invention will be described below with reference to the accompanying drawings, in which five core materials are bonded between mounts.

The one shown in FIG.
'f, This is to position the five core materials 3, as well as to correct the "crease curls" and stretch the core materials 3 to restore them horizontally. These holes 7 have a width corresponding to the width of one core material 3, and are shifted in one side direction by the width of the glue allowance piece 2b on one side of the core material 3. It has been established in stages.

Guide plates 8 are installed at both ends of the through hole 7 in a direction perpendicular to the horizontal through hole 7, and the guide plates 8 are provided slightly outward, so that when the core material 3 is inserted into the through hole 7, the core material It is easy to pass through the through hole 7 without damaging both ends of the wire.

Although the present invention has the above configuration, the width by which the positions of the through holes 7 are shifted may be smaller than the width of the glue margin piece 2b on the - side of the core material 3.

In other words, if the width is made smaller than the width of the adhesive strip 21, the distance between the horizontal part between the folds 1a and lb of the core material 3 between the mounts 4 and 5 and the adjacent horizontal part in FIG. 1 will become larger. by.

In other words, the only difference is that the square y1 of the grid body A changes to a rectangle.

Furthermore, although the explanation has been made regarding the case where the through hole 7 is provided in the plate body 6,
The through hole 7 may be provided in a three-dimensional object or an irregularly shaped object.

Since the present invention has the above-mentioned configuration, it is possible to correct the "fold crease" of the core material by adding the "first crease crease" in which it passes through the through hole, and also to easily align the core material. The core material can be adhered to the paper in its original state.

Moreover, since guide plates are attached to both ends of the through hole, the ends of the core material will not be damaged when the core material is passed through the through hole.
