Building panels, such as a floor panels or wall panels. The panels include a first mechanical locking system at respective parallel and opposite third and fourth edges, such as long edges, configured to cooperate for horizontal and vertical locking between two adjacent building panels, preferably by means of a folding motion. The panels further include a second locking system at respective parallel and opposite first and second edges, such as short edges, configured to cooperate for horizontal and vertical locking of two adjacent building panels. An upper edge portion of one of the third edge or fourth edge, preferably the third edge, includes a first lower lip portion configured to cooperate with a first upper lip portion of an upper edge portion of the other of the third and fourth edge of an adjacent panel when the third and fourth edges are arranged in locking engagement.

[Problem] To address the problem of conventional old wood texture or antique taste boards which lack natural looking worn effects and present an appearance of an artificial treatment applied thereto. [Solution] Unlike a conventional configuration in which the rotary shaft of a roll brush is simply and fixedly arranged parallel to the wood grains of a board to which surface treatment is applied or the painted surface where paint is applied to the wood grains, the rotary shaft may be obliquely set to any angle including a right angle, and may be rotationally driven at high speed at a given inclined angle relative to the horizontal surface of the board along a left to right direction of the roll brush. This makes different “contact strength” of a roll brush such as a metal brush obliquely applied to each right and left end of the board, thereby causing the inclined roll brush to peel off the wood grains or the painted surface where paint is applied to the wood grains with difference strengths for each end of the board. This makes it possible to implement “uzukuri” (brushing process) with different designs presented along a left to right direction of the board.

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.

Provided is a multi-layered reinforced wood material which is excellent in fire resistance, has extremely small damages on a support wood material part, and is also excellent in strength. The present invention is directed to a multi-layered reinforced wood material A for use as a building material, the multi-layered reinforced wood material A including a support wood material part 1 for supporting load, a sheet part 3 attached to the periphery of the support wood material part 1, an inflammable wood material part 2 attached outside the sheet part 3 so as not to expose the sheet part 3, wherein the inflammable wood material part 1 is made of a wood material containing therein an inflammable agent, and the sheet part 3 is made of a fiber reinforced plastic.

A method of drying sticks, a related apparatus, resultant product and its uses where the method involves presenting a plurality of sticks in parallel as a single layer, pressing each stick with a bank of pressing members on and/or into at least one face of the sticks, each with plurality of protuberances, thereby to constrain the sticks against crook, and drying the sticks when so constrained. Preferably each bank of pressing members is an underside of a frame or lattice of a stack of such frames or lattices able to receive such a single layer of sticks between adjacent overlying/underlying frames or lattices, the protuberances preferably being only downwardly directed.

The invention relates to a method and apparatus for activating an adhesive for composing veneers. A method for activating an adhesive for composing veneers according to an aspect of the invention comprises providing the adhesive on a surface of a veneer, and radiating the adhesive on the surface of the veneer. The method may comprise providing a reinforcing material on the adhesive; or providing an adhesive tape on the surface of the veneer, wherein the adhesive tape comprises adhesive coated or impregnated with a reinforcing material. The method may further comprise radiating the adhesive between the surface of the veneer and the reinforcing material.

The invention relates to an embryo loading device used for veneer horizontal jointing machine. The embryo loading device is characterized by comprising a clutch gear wheel part (3) and a rolling wheel part (4), wherein the clutch gear wheel part (3) is formed by a left shaped box frame (3T) and a right shaped box frame (3P), a clutch wheel (3.1), two drive shafts (3.2) and pinion (3.3). The rolling wheel part (4) according to the first embodiment of the invention is formed by a pair of two double roiling wheels (4K) composed of a rolling wheel rim (4.1), a main rolling wheel (4.2), an auxiliary rolling wheel (4.3), a polycentric coupling (4.4) and a sliding rail (4.5). In the rolling wheel part (4) according to the second embodiment of the invention, two clutch rollers (4.1C) are replaced for two double rolling wheels (4K).

The present invention relates to a flexible sheet of wood strips for use in the fabrication of engineered floor boards or wood sheets and including the machine and method of manufacture of the flexible sheet of wood strips. The wood strips provide a wood floor which has much more stability than a solid wood plank which is much more affected by the temperature in a room and the moisture under the floor board. Also solid wood planks are much more expensive than engineered wood planks where only a very thin layer of quality wood material is utilized. The transverse wood strips are constructed of inferior wood material. Two or more treads of flexible material may be secured transversely to the wood strips to provide additional retention of the wood strips in the flexible sheet.
