Building panels, especially laminated floor panels are shown, which are provided with a locking system and several core grooves at the rear side in order to save material and decrease weight. Building panels, each having a surface layer on a front side, a backing layer on a rear side and an intermediate core, wherein the intermediate core and the surface and the backing layer all comprise wood fibres and thermosetting resins, the building panels are provided with a locking system for vertical and horizontal locking of a first edge of a first building panel to an adjacent second edge of a second building panel.

The invention relates to a fitting for connecting and laying panels, boards or planks on a supporting body, having a main body and a spacer, wherein the main body has at least two fastening devices for connecting the fitting and board and for connecting the fitting and supporting surface, wherein the spacer and main body are arranged predominantly at right angles to one another in the operating state, characterized in that the main body and spacer are connectable together in a releasable manner by a third fastening device.

A faade structure is described, with a substructure formed of support profiles, which is arranged in front of a building wall and anchored fixedly in the floor and/or in the building wall, with extruded faade tiles made of ceramic material, which are fastened to the substructure via tile holders, wherein the tile holders are arranged on all or only some of the support profiles, the tile holders being fastened to the support profiles directly or via separate supports, and the tile holders having receivers, which engage with edge areas of the faade tiles to fasten the faade tiles. In order to obtain a shake-proof arrangement of the faade tiles, it is provided that press-on elements are arranged concealed behind the faade tiles supported on the substructure; and that the press-on elements are in each case assigned to only one faade tile in such a way that the press-on elements in each case grip on the back of the assigned faade tile in an area which is arranged at a distance from the tile holders gripping with their receivers on the faade tile, and the assigned faade tile is resiliently impinged on in the direction towards the front like a shake-proof receiver of the faade tile.

A faade structure is described, preferably a curtain-wall back-ventilated faade structure, with a substructure formed from support profiles which is arranged in front of a building wall and anchored fixedly in the floor and/or in the building wall, with extruded faade tiles made of ceramic material, preferably clay material, which are fastened to the substructure via tile holders. In order to be able to arrange the faade tiles in the vertical format, in addition to the tile holders which grip on the vertical edges of the faade tiles, it is provided that weight-supporting holders, which have receivers which engage in each case in a lower edge of the faade tiles, are fastened to the support profiles to which the tile holders are fastened or to further support profiles of the substructure directly or via separate supports.

A base panel suitable to be processed into a covering panel, consisting of the following layers: (i) a substrate having a top surface, (ii) a resilient layer having a top surface and a bottom surface, whereby the bottom surface is connected to the top surface of said substrate, and (iii) optionally, a contact layer between the bottom surface of said resilient layer and the top surface of said substrate. A covering panel further comprising a digitally printed decor on the top surface of the resilient layer of the base panel, and a process of producing covering panels from said base panels.

Building panels, especially laminated floor panels are shown, which are provided with a locking system and several core grooves at the rear side in order to save material and decrease weight. Building panels, each having a surface layer on a front side, a backing layer on a rear side and an intermediate core, wherein the intermediate core and the surface and the backing layer all comprise wood fibres and thermosetting resins, the building panels are provided with a locking system for vertical and horizontal locking of a first edge of a first building panel to an adjacent second edge of a second building panel.

A thermoplastic laminate plank is described wherein the thermoplastic laminate plank includes a core, a print layer, and optionally an overlay. The core includes at least one thermoplastic material and has a top surface and bottom surface wherein a print layer is affixed to the top surface of the core and an overlay layer is affixed to the top surface of the print layer. An underlay layer can be located and affixed between the bottom surface of the print layer and the top surface of the core. In addition, a method of making the thermoplastic laminate plank is further described which involves extruding at least one thermoplastic material into the shape of the core and affixing a laminate on the core, wherein the laminate comprises an overlay affixed to the top surface of the print layer and optionally an underlay layer affixed to the bottom surface of the print layer.

A structural element, including a base portion and a connecting central pin, has its base portion formed hallow, and having an internal reinforcement in the shape of WOW or MOM, to connect these elements with an insertable central pin so that the cross-section of the pin corresponds to the shape of the chamber between the reinforcements, when the upper surface of the structural element has longitudinal grooves, and is made from a modified polymer or elastomeric material comprising India rubber mixtures. The foundation is monomer ethylene propylene diene or natural rubber or styrene-butadiene rubber and/or combinations of the natural rubber/styrene-butadiene rubber, or thermoplastic elastomers, whose base is monomer ethylene-propylene-diene or polypropylene/monomer ethylene-propylene-diene or polyvinylchloride, or thermoplastic vulcanizates, whose base is monomer ethylene-propylene-diene and polyethylene or natural and/or synthetic rubber, modified by polyethylene or polypropylene.

Apparatuses and methods of operating the same are described. A plank connector that includes a body and a platform. The body may be on a first plane. The platform may be connected to the body. The platform may be on a second plane perpendicular to the first plane. The platform may include a first wing and a second wing. The first wing may extend outwardly along the second plane from the platform. The first wing may be shaped to be inserted into the groove of the first plank. The second wing may extend outwardly along the second plane from the platform. The second wing may be shaped to be inserted into the groove of the second plank.

A method or device for creating a plank. The device may include a container with an opening to receive a material. The device may also include a beam extending from a side of the container to a point in an open space of the container. The beam may have a curved shape. A portion of the material may form around the beam.
