Patent number: 6670019Abstract: In an arrangement for jointing together adjacent pieces of floor covering material, mutually facing edge portions of the pieces in a joint are profiled such that the one piece has a groove-shaped accommodation space in which a corresponding bead-shaped projection on the other piece may be accommodated. The one piece has a flocking which is disposed for holding together adjacent pieces. The profiling has, besides the accommodation space and the projection, mutually facing surfaces on both pieces, at least one of these surfaces being flocked. The flocking or flockings are located outside the defining surfaces of the accommodation space and the projection.Type: GrantFiled: May 7, 1999Date of Patent: December 30, 2003Assignee: AB GolvabiaInventor: Kjell Andersson

Patent number: 6609348Abstract: A repeating series of tiles has at least three tiles in a series. Each tile within the series has at least two sides capable of interfacing with adjacent tiles within the series. Each of the two sides of each tile within the series has a different shape in the pile direction than the other tiles within the series such that the last tile within the series is capable of interfacing with the first tile of the next series. Further, each tile within the series has at least one side capable of interfacing with at least one tile within another series in order to have adjoining rows of series of tiles. The present invention further includes both a method for producing and assembling a repeating series of tiles.Type: GrantFiled: May 8, 2002Date of Patent: August 26, 2003Assignee: Mannington Carpets, Inc.Inventor: Peter Desai
