1b veneer with irregular shape before shaping, la', lb
' is the cutting scrap, 2 is the trimmed both sides 1.1.2a, 2t
The veneer after shaping has +, and 3 is adhesive applied to one side edge end surface.

To the 01:1 surface shaping section 1o of the apparatus configured as above,
When the small veneer 1 before shaping as shown in FIG. 7(I) is fed from the side edge la, the veneer is transported in the direction of the arrow by the belt conveyor 11, and first the veneer is transported in the direction of the arrow, corresponding to the leading edge in the transport direction. The side edge 1a reaches between the light emitter 15 and the light receiver 16, which are detection means, and blocks light. Therefore, a short time after all of the light emitted from each light emitter 15 is blocked by the side edge 1a, the belt converter 11 is temporarily stopped and the running saw 1
3, the side edge 1a, which is kept from escaping upward by the veneer presser 14, is cut 1j'i by the saw.
As a result, the cut 11) (cut side edge 2a) is produced, resulting in a cut shavings 1a' as shown in FIG. 7 (II). At this time,
When the starting end 12' of the bell 1-conveyor 12 in the next stage is pulled up as shown by the chain line in FIG.
' falls naturally from between the front and rear conveyors 11 and 12 and is removed from the transport path.

Next, the beginning hj'' of the heald conveyor 12, 1 part 12'
Return to the original horizontal state, and then press both controllers ＼A11, 12 again.
When the is operated -U, one of the f1'1 plates 1 whose edge has been shaped (!!
b reaches between the light emitter 15 and the light receiver 4:41G. Next, at the moment when one of the lights emitted from each light emitter 15 comes off the IUIJ edge 1b and is not received by the light receiver 16, both conveyors 11 and 12 are stopped and the running saw 13 is started. When it is run, it is kept in a state that it does not escape upward by the plate presser 14.''The two side edges 1b are cut by the saw and become the side edges 2b with one cut and one cut, as shown in Fig. 7. This produces cutting chips 11+' as shown in CIll). After that, operate both 21 and 12 hairs 11 and 12 again, and the -Y rounded saw veneer 2 on both side edges is connected to the starting end part 12 of the rear hair.
When passing through ', pull up the beginning 1'l:1 part again, and the above ? The waste I11' is sent out from the Conhair 11 and is then sent out from between the Conhair II and 12;
It fell into the transport section 1? IA is divided from δ.

O'11 and 2 thus shaped are conveyed to conveyor 1.
2 and reaches the first turning transfer section 20, and is once received by the roller conveyor 21 without changing the transfer direction, then the belt conveyor transfer direction is changed at right angles and immediately the side edges 2a, 2b are transferred. is sent out in the direction of the arrow so that it is parallel to the transport direction,
It passes through the pinch roller 23 and heads to the adhesive application section 30 .

The shaped veneer 2 thus sent to the applicator 30 is moved toward the veneer guide 32 along the transport path by the inclined rollers of the roller conveyor 31, as shown by the arrow, and is pushed to one side by the guide. The adhesive 3 is transferred in sliding contact with the side edge 2a, contacts the rotating applicator 33 with the side edge 2a, and the adhesive 3 is applied to the end face of the side edge as shown in FIG. 7(IV).

This veneer 2 then reaches the second turning transfer section 40 and
Once received by the roller conveyor 41 without changing the conveying direction, the conveying direction is changed at right angles by the claw 43 of the belt conveyor 42, that is, the side edge 2a coated with the adhesive 3 is moved forward in the conveying direction. The feeding roller conveyor 5 of the pressurizing and heating section 50
Head to 7.

On this conveyor 57, the veneer 2 coated with the adhesive 3 is moved along its transfer path toward the veneer guide 58 by the rounded rollers of the conveyor, as shown by the arrow. , is transferred in sliding contact with the guide, and is transferred to the surface plate 51 and the pressure plate 5.
It is sent between Bell I and conveyors 53 and 54, which pass between 2 and 2.

However, since each starting end of the belt conveyor 53, 54 is equipped with a disc 55.5G that rotates at a circumferential speed slightly higher than these running speeds, the veneers 2 fed as described above are first Conveyor 57 and 53.54
While sliding in the advancing direction, both discs 55.56
(After being pulled in, it will continue to be transferred by both conveyors 5.3.54.Therefore, there is a preceding veneer between conveyors 53+54, and new veneers will be added one after another afterward.) is supplied, each of these veneers will catch up with the preceding small plate one after another between the two conhairs 53 and 54, and press their respective side edge surfaces together, as shown in FIG. 7(V). They are sequentially butted against each other and bonded together with the adhesive 3 applied to the front side edge end face in the transport direction.

On the other hand, both the upper and lower belt conveyors 53 and 54 are connected to the surface plate 51.
The veneers 2, 2, .・
. . are held in a state where they are correctly abutted on their respective f>jli1 planes while being transported. In addition, the surface plate 51 and the pressure plate 5
2 also serve as high-frequency electrodes, and generate a high-frequency electric field between the two plates using high-frequency power supplied from a high-frequency generation source. Therefore, each fl:jFi, 2 being transferred by the belt conveyor 53, 54 simultaneously passes through the high frequency electric field and is heated by its own dielectric heat generation, rapidly dissolving the adhesive 3 between the butted end faces. It is solidified and firmly bonded.

The bonded plate material thus obtained into an endless hem is sent to the next regular length cutting section 60, and is sent to the roller conveyor 61, 62.
I am drawn to it. Therefore, each time the required length of this plate material exceeds the running path of the running saw 63, the roller conveyor Gl, 62 and the heald conveyor 5 are
3. Temporarily stop both 54 and run the running saw 6.
3, the endless joint plate material is pressed down by the plate control foot 6.
At step 4, the material is cut with the saw from the point where it cannot escape upward, and the material is successively divided into pieces of required length.

As shown in the following, the present invention butts and joins two or more veneers to form a joint board of a required length. Each process includes applying adhesive to the side edge of one side of the boards, sequentially butting these veneers together, rapidly solidifying the adhesive using high-frequency heating, and then cutting to a specified length. According to the present invention, it is possible to efficiently produce a bonded board material of a required length consisting of a plurality of small veneers, and each veneer is Since the joining is due to the butt of the side edges (7jii planes),
Compared to normal scarf joining, material loss due to scarf cutting is eliminated, and the amount of adhesive used can be reduced.
