Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a method for producing an imitation tree suitable for use, for example, as a small indoor artificial Christmas tree.

``Conventional technology'' Imitation trees, which are often used for Christmas trees, are generally imitations of fir trees, and most of the tree's components (branches, leaves, etc.) are etc.) are made of synthetic resin. When producing this imitation tree, in-jection molding is used, especially for branches and leaves.

``Problems to be solved by the invention'' By the way, natural fir trees are so-called coniferous trees and have countless needles.
In order to make such an imitation tree that resembles a natural fir tree by injection molding, an extremely complicated mold is required, which inevitably results in an expensive product. Moreover, even when manufactured using such a complex mold, there are limits to the naturalness of the branches, especially those with countless needles, due to molding considerations. It still had the feel of plastic and was far from a natural fir tree.

Therefore, the present invention is easy to manufacture and can be provided at low cost.
Furthermore, the present invention aims to provide a method for producing an imitation tree that closely resembles a natural coniferous tree.

"Means for Solving the Problems" In the present invention, a leaf material having a filamentous piece or a plurality of filamentous pieces serving as one needle leaf is sandwiched between two or more linear core materials, twisted and bundled, and the A method for producing an imitation tree whose main components are a plurality of branches each having countless needles extending radially around a core material, the method comprising: using each branch material as a core material for a trunk; A step of tying the dry core material at intervals in the length direction and in a form that crosses the trunk core material, and dividing the dry core material into two pieces from a position in the middle part in the length direction. A step of overlapping the folded branches of the trunk core material so that they do not interfere with each other;
By cutting each branch material to the desired length, and by grasping both ends of the trunk core material that has been folded in half and twisting the trunk core material around its axis, each branch material is circumferentially cut. The branch material is swung out in a direction to form a three-dimensional structure of the branch material, and further includes a step of adjusting the direction of the branch material and the swinging of the branch material, and a step of adjusting the direction of each of the branch material.

"Example" Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 shows a schematic perspective view of an imitation tree resembling a fir tree created by applying the method of the present invention. It is constructed using the branch material 1 shown in the figure as the main component.

The branch material 1 has a structure having countless needles 3 extending radially around a linear core material 2, for example, a leaf material having a thread-like piece formed to resemble a single needle or a plurality of thread-like pieces. It is made by twisting and binding two or more linear core materials while continuously sandwiching them between them. Here, the manufacturing method of sandwiching the leaf materials between linear core materials, twisting and bundling can be carried out continuously by using a conventionally known automatic twisting and bundling machine. In this case, a material with sufficient stiffness, such as wire, is used to allow at least one linear core material to hold the swing of the branch material 1. The leaf material for forming the needles 3 may be colored resin filaments cut to the required length, or colored resin sheets, films, or tape-like materials with appropriate cutting lines. A device formed by integrally forming a plurality of filamentous pieces is applicable. Of course, the intended imitation tree,
For example, in the case of the fir tree in this embodiment, it is not limited to resin but may be made of other materials as long as it has a shape and color similar to the needles of the fir tree.

Next, an example of a method for manufacturing the imitation tree A using the branch material 1 having such a structure will be described with reference to FIGS. 3a, b, c, and d.

First, prepare a large number of branch materials 1 cut to approximately twice the length of the longest branch (generally the lowest branch) of the imitation tree A of the desired size, and each of these branch materials 1 As shown in FIG. 3a, two or more trunk core materials 4 are arranged so that they intersect with the trunk core materials 4 at intervals in the length direction of the trunk core materials 4. Bind sequentially. At least one of the two or more trunk core materials 4 used in the process of tying the branch materials 11 is made of a material with a certain degree of flexibility and stiffness.
For example, use wire. In this way, core material for trunk 4
If wire or the like is used for the trunk, not only will this provide the necessary strength for the trunk, but it will also improve workability since the branches 1 can be sandwiched between the trunk core materials 4 and the branches 1 can be continuously twisted and tied. desirable.

As described above, each branch material 1 is made of core material 4 for the trunk.
After completing the binding work, next fold the trunk core material 4 in two from the position of the longitudinal middle part P, as shown in Fig. 3b.
Overlap as shown. At this time, it is desirable that the branches 1 folded in half are stacked on top of each other at approximately equal intervals as shown in the illustrated example.

After superimposing them in this way, next
As shown in the figure, the left and right ends of each branch material 1 are cut using a cutter or the like in accordance with the outline of the longitudinal section of the fir tree. After this cutting operation is completed, both ends of the trunk core material 4 which has been folded in half are grabbed and twisted together to form a single trunk body. Here, when the trunk core material 4 is twisted around the axis, each branch material 1 is swung out in the circumferential direction, and is structured three-dimensionally as shown in FIG. After this, by adjusting and positioning the branches and leaves to a desired branching pattern, an imitation tree A as shown in FIG. 1 can be obtained. In addition, in FIG. 1, reference numeral 5 indicates a hole 5a for holding the imitation tree A.
It shows the base with attached.

According to the manufacturing method described above, leaf material having a filamentous piece or a plurality of filamentous pieces resembling one needle of a fir tree is manufactured in advance and these are bundled with the linear core material 2. Branch material with 3 needles and countless needles 1
By making it possible to obtain the same amount of needles as possible, it is possible to easily produce countless needles that have the texture of a very natural fir tree. In particular, since the leaf material itself that makes up the countless needles is a single piece, it is very easy to create a more natural texture by, for example, mixing leaf material with the color tone of dead leaves.
Furthermore, in order to make the entire imitation tree A, a large number of branches 1 having the above structure are twisted and tied together using a core material 4 for the trunk.
The work process is simple, such as adjusting the length of the branch material 1 and the direction of the branch (direction of the branch), and since there are very few components as a whole, the product is inexpensive.

In the above example, the length of each branch material is adjusted by cutting the tip of each branch material 1 after spreading it out into a flat shape after binding each branch material 1 with the trunk core material 4. However, the cutting process for length adjustment can be arbitrarily selected in terms of timing and cutting method. For example, Figure 3b
Each branch material 1 in the planar state shown in FIG. 4 is vertically bent as shown by the imaginary line in FIG. Also good. Alternatively, each branch 1 in the planar state shown in FIG. 3a may be cut along the positions shown by dashed lines G in FIG. 5a or b, respectively. Furthermore, each branch material 1 in the planar state shown in FIG. 3a is vertically folded around the trunk core material 4, and then
Alternatively, a method of cutting along the position indicated by the dashed line G at point b may be adopted. Moreover, it is also possible to cut each branch material 1 to a desired length in advance before binding it to the trunk core material 4.

"Effects of the Invention" As explained above, the present invention comprises sandwiching a leaf material having a filamentous piece or a plurality of filamentous pieces between two or more linear core materials, twisting and binding,
A method for manufacturing an imitation tree whose main components are a plurality of branches each having countless needles extending radially around the linear core material, the method comprising using each branch material as a trunk core material. , a step of tying the trunk core materials at intervals in the length direction and in a form that crosses the trunk core materials; A step of stacking the branches of the core material for the trunk that have been folded back to prevent them from interfering with each other, a step of cutting each of the branch materials to the desired length, and a step of cutting the branches of the core material for the trunk into two, and a step of cutting the branches into the desired length, and By grasping both ends of the core material and twisting the core material around its axis, each branch material is swung out in the circumferential direction to form a three-dimensional structure, and the direction and swing of the branch material can also be adjusted. Since the imitation tree is manufactured through this process, the following excellent effects can be achieved.

(b) Leaves with needles resembling needles or a plurality of threads are produced in advance and then bundled with a linear core material. Since the trunk core material is bound at intervals in the length direction of the trunk core material and in a form that crosses the trunk core material, countless branches with needles can be bound at adjacent positions. This can be easily carried out without interference with the bundled branches, and as a result, the workability of binding the branches and the trunk core material can be improved.

(b) Moreover, in the present invention, in the next step, the core material for the trunk, in which the branch materials are bound at intervals, is bent in two from the intermediate position in the longitudinal direction. The wood is made to be dense, so even if you leave space between the branches when tying them to the trunk core material, the manufactured imitation tree will have coarse branches. When the core material for the trunk is twisted around its axis to form each branch material three-dimensionally, each branch material closely overlaps in the vertical direction, creating a structure that closely resembles that of a natural coniferous tree. This has the effect of making it possible to create imitation trees that look very similar to natural coniferous trees.

(c) Furthermore, in the present invention, in order to create such an imitation tree with densely packed branch materials, it is necessary to bind the branch materials and the trunk core material, bend the trunk core material, cut the branch materials, and core material. Since it can be done through simple work processes such as twisting the wood and adjusting the branching, it has the effect of being able to manufacture imitation trees at low cost.
