Each thread forming profile includes a radially outermost ridge connected to a first flank and a second flank, wherein a first flank of a first thread forming profile is connected to a second flank of an adjacent second thread forming profile via a thread groove. The flanks of at least one first thread groove enclose a first angle, which is smaller than a second angle enclosed by the flanks of at least one second thread groove.

One or more collars are configured to center a rod within a drilled hole in glued-in-rod (GIR) structures. The one or more collars fit over an end and/or along a length of the rod that gets inserted first into the drilled hole. The one or more collars may include splines or other features extending from a base of the collar. The features contact walls of the drilled hole to center the rod in the hole, while at the same time allowing fluid such as glue to pass around the collar as the collar and rod are inserted into the hole.

A manufacturing cell for producing a three-dimensionally deformable wood veneer, includes a receiving surface for receiving a wood veneer to be processed, and a device for partly or completely separating the wood veneer in order to form veneer strands. The cell further includes a device for pressing the wood veneer to be processed and the veneer strands against the receiving surface. The device is designed to generate a pressure difference between a first side and a second side of the wood veneer to be processed and the veneer strands.

A method of producing a core board suitable for a coated multi-ply wood panel, as well as a coated multi-ply wood panel. The method comprises the steps of providing a wood based material in the form of a plurality of layers and an adhesive suitable for bonding the layers to each other; the layers of the wood based material and the adhesive being arranged in alternating order to form a stack, the stack having two opposite faces formed by a wood based layer. On at least one of the faces of the stack there is further provided adhesive and fibrillated fibers to form a modified stack which is pressed by one-step pressing to form a multi-ply wood panel having a facing coated with a layer of fibrillated fibers. The even and smooth surface of the core panel makes it particular suitable for coating with, e.g., glossy films.

The present disclosure provides a structural member (10), such as a beam, a stud or a joist, presenting a predetermined bending direction (B). The structural member comprises a plurality of glued-together wood lamellae (20a, 20b), each having a lamella cross section which is parallel with a cross section of the structural member (10) and a longitudinal direction which is parallel with a longitudinal direction of the structural member and with a principal grain direction of the wood lamellae (20a, 20b). In the structural member, the lamellae (20a, 20b) are formed as radial sections of a log and present cross sections which are triangular or trapezoidal and present a respective base surface (bs1) that is formed at a radially outer part of the log. The lamellae (20a, 20b) are arranged as at least one layer in which base surfaces (bs1) of a pair of immediately adjacent lamellae (20a, 20b) face opposite directions. The base surfaces (bs1) are perpendicular to the bending direction (B).

The component (100) according to the invention has a first wood element (110) with at least a first main fiber direction (114) and a second wood element (120) with at least a second main fiber direction (124). At the end, and spaced apart, the first wood element (110) is adhesively bonded, on a first side cutting through the first main fiber direction (114), to a first side (121) of the second wood element (120) cutting through the second main fiber direction (124).

A system for crafting railroad crossties of compressed bamboo is described. The system employs a hydraulic press configured to effectively compress multiple stalks of bamboo into a strong unified beam within a mold. Bamboo is first mashed, dried, and treated. A resin is employed as a permanent adhesive, binding the stalks together. The bamboo is stacked within a mold and compressed under the pressure exerted by the hydraulic press. An oven is used to heat the compressed bamboo, and then the bamboo is cooled. The compressed bamboo beam may then be trimmed to remove excess bamboo, and is cut into crosstie segments if needed. The resulting crosstie is sturdy, ecologically friendly, and rapidly manufactured.

Method for connecting a first wood element (110) with a second wood element (120), wherein the first wood element (110) comprises at least one first main fiber direction (114), wherein the second wood element (120) comprises at least one second main fiber direction (124), wherein the first wood element (110) comprises a first side (111) cutting through the first main fiber direction (114), wherein the second wood element (120) comprises a first side (121) cutting through the second main fiber direction (124), the method having the following steps: arranging the first wood element (110) on the first side (111) at a distance to the first side (121) of the second wood element (120); introducing adhesive in the space between the first side (111) of the first wood element (110) and the first side (121) of the second wood element (120); and curing the adhesive.

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.

A method for mechanically producing a wood structure with a decorative pattern is disclosed, wherein partial patterns are processed onto a working face of a wood structure by moving at least one milling cutter of a processing head of a device for patterning transversely to the wood structure with the axis of rotation of the milling cutter at an inclined angle relative to the place of the working face in such a way that grooves that form the partial pattern are formed on the working face, each of the grooves having two planes set at an angle relative to each other while the depth of the groove changes in the transverse direction of the groove. In the method, the wood structure is formed of at least two or more adjacently placed pieces of wood each having two edges, wherein several successive grooves are formed onto the working face of at least two pieces of wood with a single milling movement, each single milling movement beginning or ending at an edge of the piece of wood so that the partial patterns form together the pattern of the wood structure. A corresponding device for patterning and a decorative wood structure are also disclosed.
