Abstract

The present invention relates to a method for manufacturing a wet glued wood article, as well as a wet glued article obtainable by said method and also uses of a wet glued artice, wherein the method comprises the following steps: a) providing two actively never-dried or slightly dried wood pieces comprising at least one surface each which has a superficial layer having a thickness of least 2 - 3 wood cells; b) drying said surfaces of said wood pieces so that the moisture content of said superficial layer is below the fibre saturation point, providing a dried surface on each of the said wood pieces; c) applying a gluing agent on said dried surface of one of the wood pieces, thus providing a glue surface; d) bringing the dried surfaces together so that said glue surface touches the dried surface on the other wood piece, thus providing a wet glued wood article.

Claims (17)

Claims
1. Method for manufacturing a wet glued wood e comprising the following steps: 5 a) ing a first actively dried wood piece, comprising at least one surface which has a superficial layer having a thickness of least 2 – 3 wood cells, wherein the wood piece is a freshly sawn wood piece, b) drying the e of said wood piece so that the 10 moisture content of said superficial layer, up to a depth of from about 0.15 mm to about 0.3 mm in said wood piece, is below the fibre saturation point, providing a dried surface on said first wood piece, wherein the drying is performed at low temperature at from about 20 15 °C to about 100 °C. c) applying a gluing agent on said dried surface thus providing a glue surface, wherein said gluing agent is a polyurethane glue (PUR), d) providing a second actively never-dried wood piece 20 comprising at least one surface which has a superficial layer having a thickness of least 2 – 3 wood cells, e) drying the surface of said second wood piece so that the moisture content of said superficial layer is below the fibre saturation point, providing a dried surface on 25 said second wood piece, f) bringing said first and second dried surfaces together, so that said glue surface of the first wood piece touches said dried surface on said second wood piece, thus providing a wet glued wood e, 30 wherein said wood moisture content of the outermost layer in step b) and e) is from about 8 to about 30%.

10. A method according to claim 9, wherein the drying time is less than 15 minutes.
11. A method according to claim 10, n the drying time is less than 10 minutes.
12. A method according to any one of claims 1 to 11, wherein said drying of step b) and e) is performed using convection drying, radiation drying, contact drying, al drying or vacuum drying or combinations thereof.
13. A method according to claim 12, wherein the convection drying involves conventional convection drying, jet drying or high ature drying or combinations thereof, and the radiation drying involves infrared drying or high ncy 20 drying, or combinations thereof.
14. A method according to any one of claims 1 to 13, wherein one or both wood pieces emanates from spruce. 25 15. A method according to claim 14, wherein the spruce is
15. Norway spruce.
16. A method according to any one of claims 1 to 15, n the gluing is performed at from about 20 °C to about 100 °C.
17. A method according to claim 16, wherein the gluing is performed at from about 20 °C to about 80 °C. content moisture
