Description

[Detailed description of the invention] The invention mainly relates to general construction parts, such as surroundings, edges,
How to manufacture laminated □ boards made from veneer for use as baseboards, window frames, private residences, door frames, ducks, houses, etc. is special (Nitara・Matsu・、Akamatsu□.

The raw material is a softwood veneer such as cedar, and it is not possible to use joints such as hot melt adhesive, tape, scarf, etc., that is, at least 1'□3 or more. □A single ply of the core material layer, in other words, the core □□material layer is made of a single ply of the core material layer. □Adjacent f/end section □': M match □Mata of core material layer: Padding on front and back □111
1111 As far as the inventor and applicant know, there is no method for producing such a laminate (1).
It's not fully proposed.

That is, the object of the present invention is to eliminate the conventional hot melt yarn,
□Jointing methods such as using tape or scarf

Another object of the present invention is to obtain a bonding force similar to or greater than that obtained by conventional means 1 (each core material layer structure □ -1 (II'), which is strongly integrated with the veneer of the board.

6. To provide a method for manufacturing a laminate that can produce products.

Adjacent ends/a of each veneer/ply P for the core material, Jtii lumberjack, are polymerized to a thickness of about λ~10 mm as shown in Fig. 7, and the front and back panels are each Adjacent ends 2a of the veneers are butt jointed. Then, using a desired resin adhesive, adhesive is applied from above and below under appropriate pressure (for example, !~/θKp/cm). This pressure:
As shown in Fig. 2, the end portions/a are deformed into a planar shape as shown in Fig. 2;

Since the present invention is constructed as described above, compared to conventional joining means using hot melt threads, tapes, scarves, etc., the process is much simpler, the cost is much lower, and the joint is strong. It is something that can be achieved by integrating.
