Patent number: 9422727Abstract: A joint for panels, the panels comprising a core, a decorative upper surface and edges provided with joining means for positioning the panels towards one another. Predetermined portions of the edges are provided with a layer of polymer. The panels are joined to one another by use of the joining means where the polymer forms a seal in the joint preventing penetration of water into the joint wherein a highly water resistant unit of a plurality of panels is formed.Type: GrantFiled: September 14, 2012Date of Patent: August 23, 2016Assignee: PERGO (EUROPE) ABInventors: Ake Sjoberg, Hakan Wernersson, Krister Hansson, Magnus Nilsson, Nils-Erik Engstrom, Sven Kornfalt

Patent number: 8448399Abstract: A thin decorative thermosetting laminate of postforming quality is glued to a longitudinal carrier to form a floor strip. The laminate has a thermosetting resin as well as hard particles impregnated therein to increase the abrasion resistance of the laminate. The carrier generally has a cross section of a dilatation, transition or a finishing profile, depending on the intended use of the floor strip. The floor strip has a tab portion on a surface that engages a channel on a floor tile or a reducer. The tab portion locks the floor strip into place and prevents movement of the floor tile or the reducer with respect to the floor strip.Type: GrantFiled: December 18, 2006Date of Patent: May 28, 2013Assignee: Pergo (Europe) ABInventors: Sven Kornfalt, Per Bengtsson, Hans Sjolin, Oliver Stanchfield
