Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for filling cracks in veneer veneer.

Conventionally, a veneer with a crack extending in the direction of the fibers was removed by cutting 61 pieces of neighboring veneer to remove the crack.
Therefore, the resulting drop in yield is significant.

On the other hand, in the invention of Japanese Patent Application Laid-open No. 55-614098, which is the original application of the present application, a reinforced veneer configured to strengthen this type of cracking and a method for manufacturing the same are provided, and the veneer mainly expands and contracts during drying and moisture absorption. It also has extremely excellent properties against the wire coming off, which occurs twice in practice.

The present invention makes the provision of such a reinforced veneer even more effective. The A7 is designed to eliminate the above-mentioned drop in yield, and its details will be described below based on the drawings illustrating it.

In other words, as illustrated in FIG.
For example, a wire rod 4 as shown in FIG. A wire rod press-fitting knife 8, which has no cutting edge only at the abutting portion 7, is inserted into the wood 1 of the veneer 1 or the board surface to fix the wire rod 4 as shown in FIG. 3 or 4. The part that has not been replaced is distorted to its original buried state, and the front part 8 is made old.

In this way (6 [I] in the method of the present invention), since the wire rod 4 in the cut 3 is partially fixed to the veneer, the state of the unfixed part changes extremely reliably and sharply. ,
It is possible to stuff the 16th part of the veneer 1 (strain, so 11).
＼The degree of intervention is also slight.

Of course, after filling the 9 cracks 6, the unfixed portions of the wire 4 are pinched due to the restoring force of the veneer fibers, tending to maintain the strained state, and the wire rods 4 are pressed into place. Traces of knife intervention 9
There is no particular problem.

In addition, there is one application (regarding the veneer I to which the iron is applied, as follows).

An example of the manufacturing method will be explained in detail based on FIGS. 5 to 8.

The example shown in FIGS. 5 and 6 is a wood-forming cutter 3 which is formed so that each cutting edge is substantially orthogonal and has a moss pulling blade part 11 and a cutting blade part j2. (3) Direction 1, that is, the cutting edge of the cutting blade part 12, is a veneer cutting knife. 1 alloy 14 toward substantially the same direction as the cutting edge of the object jO
In preparation for the cutting head for attaching the prennoyaher etc. through the
Cut the veneer I from 4f by rotating the veneer A. Form the end of the board 1
The cutting blade part 12 is attached near the end, and the guide hole 16 of the wire rod is impregnated or coated with adhesive 5 at every arbitrary distance.
The veneer described above is produced by inserting a wire rod 4 and guiding and burying the wire rod 4 in the cut 3.

Another method, as illustrated in FIGS. 7 and 8, is that each cutting edge is formed so as to be substantially orthogonal to the moss drawing blade part 1] and the cutting blade part 12. The blade 13 for forming the book 11 has a cutting edge 11 for cutting the cutting blade 11 in a direction substantially perpendicular to the cutting blade 10 for cutting the veneer and the lace, that is, the cutting edge of the cutting blade 12 for cutting the veneer. The cutting edge of the cutter 10 is substantially the same as the cutting edge of the cutter 10 (in substantially the same direction as the blade 14). While cutting the veneer 1, a cut 3 of an appropriate depth along the end of the veneer L is also formed in the veneer wood E' section, and only the cutting blade part 12 is cut near the end. ] The wire rod 4 is inserted through the provided wire guide hole 1 (i), and the wire rod 4 is guided and buried in the cut 3 as shown in FIG.

Adhesive 5 is introduced into the guide hole 17 of the adhesive member provided near the tip of the cutting blade 12, and the adhesive 5 is intermittently discharged at arbitrary distances and embedded in the cut 3. The veneer described above is manufactured using the following methods.

In addition, whichever method is used (in this case, the adhesive 5 is a wet curing adhesive, a room temperature curing adhesive, a heat curing adhesive, etc., which is common in the plywood industry (this method is not used). Any adhesive may be used, and if necessary, two or more of the adhesives may be used in combination.

Furthermore, the curing process for this adhesive is determined depending on the type of adhesive; for example, it may be cured during transport, during deposition, or during the drying process of the next process. It is also possible to make the wire rod into a heat-shrinkable (5) wire rod, or to apply appropriate tension to the wire rod by appropriate means.

Furthermore, if the wire is a thermofusible wire and a portion of the wire is melted at arbitrary distances and fixed to the veneer using an appropriate means, the use of adhesive is not necessary in the method exemplified above.

Claims (1)

[Claims] A cut is made at the end of the veneer that has a crack extending in the direction of the fibers, and the wire is inserted at arbitrary distances into the veneer in parts of the veneer (this part is fixed while other parts are not fixed). A method for filling cracks in a veneer, characterized by intervening a wire press-fitting knife in the buried veneer to distort the unfixed portion of the wire from its original buried state to fill the crack.
