Abstract
Method and press for producing a curved laminated wood module including a plurality of laminated veneer lumber (LVL) boards, where the press includes a convex mold, where the mold is arranged on a frame, and where the press includes an upper part adapted to be placed on the plurality of LVL boards, where the press further includes a plurality of pulling brackets and pulling means attached between the frame and the pulling brackets, where the pulling means are arranged to pull the pulling brackets towards the frame until the plurality of LVL boards bears completely on the mold.
Claims19
A press for producing a curved laminated wood module comprising a plurality of laminated veneer lumber (LVL) boards, the press comprising:
- a convex mold adapted to receive the plurality of LVL boards on an outer surface, where the mold is arranged on a frame;
- an upper part adapted to be placed on the plurality of LVL boards, such that the plurality of LVL boards are held between the mold and the upper part, wherein the upper part comprises a plurality of pulling brackets arranged at the long sides of the press;
- and
- pulling means attached between the frame and the pulling brackets, where the pulling means are arranged to pull the pulling brackets towards the frame until the plurality of LVL boards bears completely on the outer surface of the mold,
- wherein the frame comprises a plurality of beams, where each beam is provided with two extendable members arranged at each side of the beam, and where the extendable members are arranged to provide a pressure to the pulling means.
A method for producing a curved laminated wood module comprising a plurality of laminated veneer lumber (LVL) boards, the method comprising the steps of:
- placing one of the plurality of LVL boards on a convex mold arranged on a frame, wherein the frame comprises a plurality of beams, where each beam is provided with two extendable members arranged at each side of the beam;
- applying a glue layer on the LVL board before the next LVL board is placed on the previous LVL board, until all LVL boards are placed on the mold;
- placing an upper part on the plurality of LVL boards;
- pulling the long sides of the upper part towards an outer surface of the mold with pulling means until the plurality of LVL boards bears completely on the outer surface of the mold, where the extendable members are arranged to provide a pressure to the pulling means;
- holding the plurality of LVL boards pressed against the mold until the glue has cured;
- releasing the pulling means;
- and
- removing the curved laminated wood module from the press.
