DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glue press and a method for producing a glue for the production of a large variety of small lots.

[0002]

2. Description of the Related Art Heretofore, it has been practiced to fill a laminated material press with a unit material coated with an adhesive and press it to obtain a laminated material. However, in the conventional laminated wood press, since the press cylinder is fixed to the press, the center of the unit material to be pressed cannot be pressed accurately.

[0003] Glued laminated materials having different dimensions cannot be simultaneously produced by one press. In other words, the size of the glulam differs according to the requirements of the building,
Although multi-product, small-lot production is required, the conventional laminated wood press could not meet such demands.

[0004]

When a laminated material is obtained by pressing a unit material with a laminated material press, the center of the press is accurately centered. To enable the production of glued laminated lumber according to the requirements of high-mix low-volume production with one press.

[0005]

A laminated wood press that can be filled into case 1.

(Second Invention) Unit materials 2a which can be adhered to each other by applying an adhesive 2b are stacked and filled in a press case 1, and pressed and joined by a press device 3, and the press device 3 is used alone. Using a glue press capable of moving in the width direction of the unit material 2a, the unit material 2a is stacked in the lower stage to form a unit material stack that can be bonded to each other, and the upper unit is formed from the length of the lower unit material 2a. A stack of short unit materials is placed on a unit material stack that can be adhered to each other, and a plurality of the press devices 3 are provided,

[0008] A method for manufacturing a laminated material, wherein the stacked unit materials 2a having different lengths are simultaneously pressed by the plurality of pressing devices 3 at the upper and lower stages.
