Title
(EN) METHOD FOR PRODUCING MECHANICAL LOCKING SYSTEMS IN A BUILDING PANEL
(FR) PROCÉDÉ DE FABRICATION DE SYSTÈMES DE VERROUILLAGE MÉCANIQUES DANS UN PANNEAU DE CONSTRUCTION
Abstract
(EN)
Building panels, such as a floor panels or wall panels. The panels comprising a first mechanical locking system at respective parallel and opposite third and fourth edges (13, 14), such as long edges, configured to cooperate for horizontal and vertical locking between two adjacent building panels (10, 20), preferably by means of a folding motion. The panels further comprising a second locking system at respective parallel and opposite first and second edges (11, 12), such as short edges, configured to cooperate for horizontal and vertical locking of two adjacent building panels (10, 30). An upper edge portion of one of the third edge or fourth edge (13, 14), preferably the third edge (13), comprises a first lower lip portion (139) configured to cooperate with a first upper lip portion (149)of an upper edge portion of the other of the third and fourth edge of an adjacent panel (20) when the third and fourth edges are arranged in locking engagement.
(FR)
L'invention a trait à des panneaux de construction, tels que des panneaux de plancher ou des panneaux muraux. Les panneaux comprennent un premier système de verrouillage mécanique à des troisième et quatrième bords (13, 14) respectivement parallèles et opposés, tels que des bords longs, configurés pour coopérer pour le verrouillage horizontal et vertical entre deux panneaux de construction adjacents (10, 20), de préférence au moyen d'un mouvement de pliage. Les panneaux comprennent en outre un second système de verrouillage à des premier et deuxième bords (11, 12) respectivement parallèles et opposés, tels que des bords courts, configurés pour coopérer pour le verrouillage horizontal et vertical de deux panneaux de construction adjacents (10, 30). Une partie de bord supérieur de l'un du troisième bord et du quatrième bord (13, 14), de préférence le troisième bord (13), comprend une première partie de lèvre inférieure (139) configurée pour coopérer avec une première partie de lèvre supérieure (149) d'une partie de bord supérieur de l'autre des troisième et quatrième bords d'un panneau adjacent (20) lorsque les troisième et quatrième bords sont agencés en prise de verrouillage.
