Automatic machine for width gluing of wooden lamellas into laminated plates of optional dimensions and a method relating thereto
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.
MAKING PROFILE-EDGE CONSTRUCTION BOARD
Construction board is made by first hot-pressing particles in a continuous belt press to form a longitudinally extending, continuous and hot composite strand that is conveyed downstream from the press. Before substantial cooling of the boards and while it is at a predetermined temperature above ambient temperature, an edge of the strand is profiled into a nonsquare profiled contour. Then the strand is transversely severed to form a succession of boards.
METHOD AND SYSTEM FOR PRODUCING A THREE-DIMENSIONALLY DEFORMED PLATE
A method for manufacturing a three-dimensionally deformed plate made of a wood fiber material comprises providing a prefabricated, flat wood fiber material plate as the original plate, preheating the original plate in sections, wetting the preheated section of the original plate with an atomized liquid mixture of water and a separating agent, introducing a section of the original plate that is preheated and wetted with a liquid mixture of water and a separating agent between two rollers of a molding station, wherein the rollers respectively provide a corrugated profile in the peripheral direction of the external surface, such that the original plate is being deformed in sections into a plate with a wave shape, wherein rollers are being used, the respective profiling of which has half-waves which follow one another in the peripheral direction and which at least partially have a different extension in the peripheral direction.
COVERED PANEL AND METHOD FOR MANUFACTURING COVERED PANELS
Coated panel with at least a substrate (2) and a top layer applied thereto (3), wherein the above-mentioned top layer (3) comprises at least a decor layer (4) and a translucent or transparent wear layer (5), characterized in that the above-mentioned wear layer (5) comprises a thermally cured acrylate resin or a thermally cured unsaturated polyester resin. Preferably, wherein thermal curing partially or completely cures the resin. In particular, wherein the above-mentioned acrylate resin or unsaturated polyester resin is at least partially cured by means of a thermally initiated radical crosslinking reaction. The invention further relates to a method for the production of such coated panels (1), in particular floor panels.

BOARD AND FLOOR PANEL BASED ON SUCH BOARD
Sheet material includes at least two layers of material, wherein a first layer of material forms more than half the thickness of the sheet material and is mainly built up from wood particles glued by means of a first binder and pressed. The first binder is thermosetting, wherein the second layer of material is present on the surface of the aforementioned sheet material and is mainly built up from particulate particles glued by a second binder and pressed. The second binder is thermoplastic and/or elastomeric.
Lapper assembly
The present disclosure provides embodiments of a lapper assembly for use to overlap successive sheets of wood veneer or other materials along a conveyor. The lapper assembly may include a stop member configured to be rotatably mounted to a roller such that the stop member is pivotable around the rotational axis of the roller independently of the rotational angle of the roller. The lapper assembly may further include a lever arm coupled to one end of the stop member. An actuator may be pivotably coupled to the lever arm and the conveyor frame, and operated to pivot the stop member between a workpiece engaging position, in which the stop member extends into the path of workpiece flow, and a workpiece disengaging position below the path. Optionally, the lapper assembly roller and other rollers upstream/downstream may be operatively connected to a drive. Corresponding systems and methods are also disclosed herein.
