Apparatus for laminating wooden strips

Claim 1

An apparatus for uniting and shaping in one operation adherent layers of freshly glued laminated wooden strips into a beam, said apparatus comprising: a base, a rigid frame mounted on said base used as a forming surface against which the layers of laminated wooden strips are juxtaposed thereto, an arcuate-shaped elastic beam mounted on said base for movement into juxaposed relationship with the layers of laminated wooden strips positioned adjacent said frame, said elastic beam being formed for engaging pressure first on a position between the ends of the laminated wooden strips and thereafter progressively toward both ends of the laminated wooden strips, and releasable clamping means extending between the ends of said frame and the ends of said elastic beam for producing clamping pressure on said laminated wooden strips, said clamping means causing longitudinal movement of said laminated wooden strips relative to each other progressively from the initial contact point of the elastic beam on the laminated wooden strips toward their ends, and said elastic beam when tightly engaging the ends of the laminated wooden strips and assuming substantially the configuration of the rigid frame applying equal pressure to the laminated wooden strips along their length.

Claim 2

An apparatus for uniting and shaping in one operation adherent layers of freshly glued laminated wooden strips into a beam, said apparatus comprising: a base, a rigid frame mounted on said base used as a forming surface against which the layers of laminated wooden strips are juxtaposed thereto, an arcuate-shaped elastic beam mounted on said base for movement into juxaposed relationship with the layers of laminated wooden strips positioned adjacent said frame, said elastic beam being formed for engaging pressure first on a position between the ends of the laminated wooden strips and thereafter progressively toward both ends of the laminated wooden strips, and releasable clamping means extending between the ends of said frame and the ends of said elastic beam for producing clamping pressure on said laminated wooden strips, said clamping means causing longitudinal movement of said laminated wooden strips relative to each other progressively from the initial contact point of the elastic beam on the laminated wooden strips toward their ends, and said elastic beam when tightly engaging the ends of the laminated wooden strips and assuming substantially the configuration of the rigid frame applying equal pressure to the laminated wooden strips along their length.

Claim 10

A method of forming laminated wooden beams comprising the steps of: juxtaposing freshly glued wooden laminated strips to form a beam, juxtaposing one surface of said beam to a rigid frame having a given configuration, moving a curved surface of an elastic beam into contact with said beam on the opposite surface to that engaging said frame, and applying pressure between the ends of said elastic beam and the ends of said frame, causing longitudinal movement of said strips relative to each other until said elastic beam applies equal pressure to said laminated beam along its length.

Claim 11

A method of forming laminated wooden beams comprising the steps of: juxtaposing freshly glued wooden laminated strips to form a beam, juxtaposing one surface of said beam to a rigid frame having a given configuration, moving a curved surface of an elastic beam into contact with said beam on the opposite surface to that engaging said frame, and applying pressure between the ends of said elastic beam and the ends of said frame, causing longitudinal movement of said strips relative to each other until said elastic beam applies equal pressure to said laminated beam along its length.
