Description

[Detailed Description of the Invention] The present invention is a method for reinforcing the end surface of a veneer veneer, in particular, a process for reinforcing the end surface of a veneer veneer. This is related to the method number.

Conventionally, veneer ft& (hereinafter referred to as 41t)

Does the present invention overcome the drawbacks of such conventional methods? This was developed to solve the problem, and the basic structure of the invention 15M is to stack the assembled boards once with their butt ends aligned, and in the stacked state, attach a sleeve glaze to the end of the board. The point at which each veneer of the bond is taken out (this is a very convenient and cheap method for quick reinforcement and treatment) is shown below.
I will explain based on y + mouth.

The #1 invention of the present invention is to deposit single pieces with their butt sides, layer the aligned butt ends of the pieces, and then peel off the pieces by fourteen pieces each. As shown in Figure 1, the veneer 1 is deposited on the desired side with the end direction 1a aligned, and then the reinforcing material is applied to the end surface 1a, and each grafting agent is applied to the end surface 1a. 2 is applied by brushing or spraying the adhesive 2, and after the adhesion agent 2 has hardened, the valley copying plate 1 is peeled off one by one and rl.
It takes out the l1 order.

It is possible to deposit veneers using the techniques disclosed in Japanese Patent Publication No. 25959 and Japanese Patent Publication No. 56-156113.

Of course, the gi root deposited here is not limited to a single piece of fixed length, but it can also be a small width A&, or a Q'ffi contact or a horizontal contact without sprouting. The temples that are placed in parallel in a close state are also meant to be worshiped, and it is true.
A similar effect can be achieved for i as well.

In addition, the process ship which removes the acid roots one by one from the ψ11 distance L/manufacturer has to do it easily by hand θ). If you have [subspecified monosaka automatic ejection device] 4 times a month,

6 inversions for 11 ml. The contact agent is N to the wood end surface.
The rubbing from the surface st can be achieved by simply applying it beforehand, making it extremely easy and convenient to use as a reinforcing material. In addition, on the other hand, polyurethane, vinyl acetate, and other adhesive agents, which have some elasticity even after hardening, can be used to easily break up the contact layer 1-, but are not soft in the layer 4i. Q) that does not impair the quality is preferable. In addition, we added the short mechanical fiber test material consisting of glass fibers, 8-goku fibers, etc., and added the ml recorder.
4'+, 412's 617ii and 40 pieces in a row make it easier to handle. Here, it may be difficult to reduce the number of contact layers to one layer, but if fJ does not splash when touched by hand, it can be considered that it has hardened. It is also possible to peel it off.G
If you rub it, you can also reinforce it by pasting a non-soft plastic film over it.

Next, we will discuss an example using Kameya Kono as a lantern, focusing on the adhesive.

Then, apply or impregnate the end surface of the acid root with the undiluted solution or one diluted with water to an excess of 100% (Shigenobu') as required, until the minimum enclosing agent completes gelation. is allowed to cure until semi-hardened or becomes fecalized. Usually the curing time is
When used as a liquid, the temperature is about 1 to 1 () minutes at 81f, and when diluted, it is 5 to 60 minutes at 8 degrees, and of course it can be cured for longer than that and then peeled off.

As mentioned above (reinforcement of the end face of the veneer with the ends aligned and piled up) will not only prevent the occurrence of black distortion when reinforcing the raw wood, but also prevent the reinforcement from occurring. In addition to making the layering uniform, it is possible to give the necessary amount of hardening time for reinforcement, and as a whole, stable reinforced ripened eggs can be produced with oT.
NI;

In addition, since the reinforcing material is attached only to the butt end surface of the nail plate, there is no possibility of poor adhesion due to uneven thickness during molding of the nail plate, and instead it is possible to reinforce the acid roots of young fruits.

The second invention will be briefly explained.

The invention of the second blue eye is an improvement of the first invention described in 1j, and when depositing turtle 4#i & its end surfaces with the edges aligned, at least one end is placed between the surfaces of the porcelain plates as a veneer. The pressure of the wire protruding from the electric board fiber is divided in the direction across the electric board fibers, and the end surface of the wire rod (f?Mfl) is temporarily attached. It is characterized by taking out the valley μ plates one by one while separating them by 111 degrees while pulling in the turning direction.
Then, connect the wire 4,1' 3 protruding from the heavy plate 1 at one end to
It is deposited near the end surface 1a of the board, parallel to the end surface 1a, and then, as in the embodiment shown in FIG. Then, on the platform from which each turtle root 1 is taken out, the ends of the leg strips 5 are pulled upwards, and the legs are peeled off one by one.

The rift recording material 6 is usually natural fiber or base material,
It is preferable to use a thread made of fiber or the like, or a thin and strong material such as pure gold pI4III, or a material made of tape (tape) may also be used. In addition, from the viewpoint of preventing the reinforcing material from being used, it is desirable that the position of the wire @6 be as close to the IJiL provisional butt end surface as possible, and parallel to the butt end surface.
In experiments, effective results were obtained when the distance from the butt end surface was within about twice the length of the single root bank. In addition, the ends of the Y4tl yarn are made to protrude from the edge of the veneer so that they can be easily pulled, but when pulling by hand, it is easier to pull by holding both ends of the veneer. Therefore, it is desirable to deposit the wire with both ends protruding from Rt&.On the other hand, if we consider the collection of the wire by mechanical means, it is preferable to deposit the wire in a continuous manner. The most convenient method is to interpose the IQ while repeating and turning the numbers, and it is better to have more than one number.

This wire rod 6 is interposed to make it easier to take out the veneer 1, but it also has the effect of ensuring that the reinforcing layer is separated, so that the wire rod 6 can be moved more toward the wood end. It is possible to carry out the cutting more effectively by intervening near 1a (or by pulling the cutting board 6 diagonally upward near the end surface 1a).

In the above aspect, the second invention is to peel each veneer one by one while pulling the end of the wire with the torsion plate surface open in the direction of turning over the veneers. , without applying excessive force to the grain of the veneer, it is possible to stably eject the veneer even when the veneer is comparatively thin or on a soft lifting platform, and the effect is It will double.

rK&K congratulates you on your sixth defense.

There is a difference here. That is, the fifth invention relates to the above-mentioned removal of the wafer, and is characterized in that the end of the wire is pulled parallel to the plate surface and in a direction that assists the J- of the reinforcing material. The plan is to take out the m plate after a minute to f.

Fig. 3 shows an example of this, in which the wire rod 6 is deposited through the wire rod 6, and two supplementary forces are attached to the end surface 1a of the stop plate 1, and the end of the wire rod 6 is pulled in the direction of the arrow. By 111 S+
The reinforcing material 1-2 is assisted by L1 to take out the Toshinori knitting board 1.

In the present invention, the wire rod 6 is used only to prevent an increase in the reinforcing material 412, and the veneer 1 is taken out into the dividing portion of this reinforcing material. Therefore, at the final completion stage, the IJi root extraction process P46'--no limit is added, and it is possible to sequentially extract it in any direction.

As shown above, the sixth invention is a method in which the edge of the cut-out which is interposed between the faces of the tortoise (-!) is the board face and the end face of the board, and also includes the butt end face number. It is important to pull the force in the direction of +u+-f.

No matter which invention is made in Gakko 1, should the butt side of the 111 board be entirely reinforced with W, tlII, or locally reinforced with C2, or should the father rub one of the butt ends + 111 with ζ? Regarding the second point of reinforcing both sides, it is best to consider the quality of the veneer to be treated, the quality of the veneer, and make a decision as appropriate. Also, as a matter of course, regarding the 3 matters that are followed by Tani Invention, I will only describe them here in the 6th brother of the first defense, and the following explanation (maybe they have been omitted here, or all of them are matters a). (Regarding 3, please note that no matter what invention you come up with, you will be disappointed.)

It is clear from the above that the present invention can be carried out accurately and cheaply based on the conventional method, and the base plate work of Mizumoto 11) 4i The young fruit is extremely large.
