The present invention concerns the provision of a novel glue application apparatus for controllably depositing glue on the mating surfaces of door components in a manner that provides adequate glue coverage while preventing the deposition of excessive amounts of glue. The glue application apparatus includes multiple glue dispensers having uniquely configured glue dispensing nozzles that are uniquely positioned at various angles to accommodate mating surfaces of different profiles.

A method of manufacturing a curved shaped object formed primarily of plywood, the method comprising: cutting strips from a plywood panel; and arranging and bending the strips in two different directions. The strips can have edges that have a wavy profile. The strips can be arranged in a multi-layer stack where they are staggered or crossed. The object is at least partially ovoid in shape.

A cross-laminated timber processing equipment comprises a longitudinal board loading mechanism, a transverse board loading mechanism, an adhesive spraying mechanism, laying cars, presses, a transfer car, and an unloading car. The longitudinal board loading mechanism lays longitudinal boards on a laying car at an assembly station, and the transverse board loading mechanism lays transverse boards on the laying car. The longitudinal boards and the transverse boards are perpendicularly and alternately laid layer by layer. The adhesive spraying mechanism is provided above the assembly station, and sprays an adhesive on the upper surfaces of assembled boards. The transfer car moves back and forth between a conveying station and an idle press through the assembly station, carries the laying cars and the assembled boards, and feeds the laying cars and the assembled boards into the presses for compaction. The unloading car moves back and forth between a press completing compaction and an unloading station, and conveys an idle laying car to the assembly station. Compared with other international similar equipment, this equipment can implement fully-automatic cross-laminated timber processing and production, and has low apparatus cost, high production capacity, high processing efficiency, and a great leading advantage.

A bar element as a construction element includes strips preferably produced from bamboo and is hollow at least in certain regions. The hollow interior is formed at least in certain sections as a hollow fillet achieved by a plastic and/or resin introduced into the bar elements, using a shaped body movable through the interior. Producing bar elements from interconnected strips ensures that although produced from a natural raw material, the bar elements have a reproducible outer cross section. Using a shaped body movable through the interior to produce the inner cross section also ensures a defined inner cross section of the bar elements, with the result that in turn connections between a plurality of bar elements that are defined by suitable connection elements can be formed. In this way, the bar elements make it possible to produce lattice works, grid constructions, frameworks or other desired structures and/or three-dimensional bodies.

An automatic machine for width gluing of wooden lamellas into laminated plates of optional dimensions according to the invention consists of a press and a glue application device and enables fast continuous gluing of wooden lamellas of optional lengths, widths and thicknesses into laminated plates also of optional dimensions. The press is characterized by a modular construction, which consists of innovative supporting framework segments with intermediate work modules in a sequential string, which together enable transport of wooden lamellas, their pressing and gluing in the same plane within the entire construction of the press. Each work module consists of a work table assembly, a pressure shoes assembly and a segment pushers assembly. Within these assemblies, innovative constructions of segment pushers, long pressure shoes and short pressure shoes are characteristic.

A laminated wood product comprising providing a plank presenting a pair of parallel major surfaces, a pair of minor surfaces, a pair of end surfaces and a longitudinal direction parallel with said major and minor surfaces and perpendicular to the end surfaces, said plank having a water content of more than 25% by weight, preferably more than 30% by weight. At least one of the major surfaces is laminated to a surface of a second member.

The present disclosure relates to a method of producing a laminated wood product, comprising providing a plank presenting a pair of parallel major surfaces, a pair of minor surfaces, a pair of end surfaces and a longitudinal direction parallel with said major and minor surfaces and perpendicular to the end surfaces, said plank having a water content of more than 25% by weight, preferably more than 30% by weight, initializing at least one longitudinal crack in the plank, drying said crack initialized plank to a moisture content of less than 20% by weight, and laminating said crack initialized plank by gluing at least one of its major surfaces to a surface of a second member, thus forming the laminated wood product. The disclosure also relates to a laminated wood product, which may be formed according to the method.

Embodiments of the invention are directed to systems, methods and computer program products for optimizing wood panel creation. An exemplary apparatus is configured to receive information related to a customer order; assemble, based at least partially on the received information, a plurality of wooden staves; adhere the plurality of wooden staves to one another such that a ribbon of staves is formed; position the ribbon of staves on a first conveyor belt such that it is transferred to a portion of the device for curing; cure the ribbon of staves using the fourth unit of the production device; resize such that a panel is formed, wherein resizing the ribbon of staves comprises removing an excess portion of the ribbon of staves; and return the excess portion of the ribbon of staves on a second conveyor belt to another unit of the production device.

The present disclosure provides a method of forming a laminated wood product, which is adapted for receiving a load in a direction perpendicular to a principal fiber direction of the wood. The method comprises cutting a log (2) along the principal fiber direction of the log, into a plurality of wood lamellae (20a, 20b), such that the wood lamellae are formed as radial sections of the log, forming the wood lamellae (20a, 20b) to provide each wood lamella with a trapezoidal cross section, whereby the wood lamellae present a respective planar major base surface (bs1) that is formed at a radially outer part of the log (2) and a respective planar minor base surface (bs2) that is formed at a radially inner part of the log (2), arranging the lamellae (20a, 20b) as at least one layer in which planar major base surfaces (bs1) of immediately adjacent lamellae (20a, 20b) face opposite directions, and gluing together the lamellae (20a, 20b) side surface to side surface (ss1, ss2) such that a wood billet is formed. The method further comprises arranging the wood lamellae (20a, b) such that the major base surfaces (bs1) of immediately adjacent wood lamellae taper in opposite directions, and the gluing comprises wet gluing.
