Abstract
Floor covering, consisting of floor panels (1) based on a fiber-like material bound by a binding agent, more particularly MDF or HDF, which, at least at their edges, are connected to each other by means of a connection, more particularly a tongue-and-groove connection (2-3) which connection consists of coupling parts which are made in one piece with the floor panels and is shaped in such a manner that the floor panels (1) are locked glue-free in the direction parallel to the plane of the floor covering and transverse to the connection, as well as in a direction perpendicular to this plane, characterized in that, at least at the location where the floor panels (1) cooperate with each other, a sliding agent (12-12A) is provided at least on one of the floor panels (1).
Claims31
A flooring panel comprising a laminated panel having an MDF/HDF core material and a decorative top surface layer on a top side of the panel terminating at opposed upper edges;
- said panel including at least two opposed pairs of side edges;
- tongue and groove connector parts extending along at least one of said pairs of opposed side edges, said connector parts cooperating with each other to couple two ones of said panels to each other along adjacent side edges by means of said connector parts by a tongue part fitting in a groove part;
- said connector parts including locking portions cooperating to lock the panels against panel separation in directions parallel with the panel top side and perpendicular to the panel top side and perpendicular to the side edges, upon coupling of connected parts of a pair of panels;
- said tongue and groove coupling parts made from MDF/HDF core material;
- and a non-metallic sliding agent layer on the surface of at least a portion of a panel edge including a tongue or groove connector part.
A flooring panel comprising a laminated panel having an MDF/HDF core material and a decorative top surface layer on a top side of the panel terminating at opposed upper edges;
- said panel including at least two opposed pairs of side edges;
- tongue and groove connector parts extending along at least one of said pairs of opposed side edges, said connector parts cooperatirig with each other to couple two ones of said panels to each other along adjacent side edges by means of said connector parts by a tongue part fitting in a groove part;
- said connector parts including locking portions cooperating upon coupling parts being coupled to lock the panels against panel separation in directions parallel with the panel top side and perpendicular to the panel top side and perpendicular to the side edges, upon coupling of said connector parts of a pair of panels;
- said tongue and groove connector parts made from MDF/HDF core material;
- and an elastic coating provided on at least a portion of one of said opposed side edges including one of said tongue and groove connector parts, said elastic coating having elastic properties enabling the elastic coating to accommodate, within its thickness, slight movement between surfaces of pairs of coupled panels connected together at respective connector parts on which said elastic coating is provided without relative surface to surface motion between the surfaces and the adjacent elastic coating.
A method for making a floor covering panel comprising the steps:
- forming a flooring panel having opposed side edges;
- milling a tongue profile and a groove profile at two or more of said edges;
- applying a liquid mixture of sealing agent and sliding agent on said edges, including permitting at least part of the sealing agent to be absorbed in the material of the floor panel and with at least part of the sliding agent remaining on the surface of the edges as a solid layer.
