Patent

CA 2618496

The invention relates to a method for production of panels for floor, wall or ceiling coverings, with the panels being cut from a large starting sheet and provided on their long sides (11, 12) with locking strips (15, 16). The starting sheet is hereby provided with parallel grooves (4, 5) along the topside and underside thereof, with the upper groove (4) and the lower groove (5) extending in the sheet plane (PE) at an offset in relation to one another at a distance (a), thereby forming a breaking web (6). The starting sheet (1) is then divided along the breaking web (6) such that projecting longitudinal strips remain along the long sides (11, 12) and are used for shaping the locking strips (15, 16).

L'invention concerne un procédé de production de panneaux pour des revêtements de sols ou de plafonds ou des revêtements muraux. Ces panneaux sont découpés dans une plaque de départ de grande taille et ils sont pourvus de languettes de verrouillage (15, 16) sur leurs côtés longitudinaux (11, 12). A cet effet, la plaque de départ est pourvue de rainures parallèles (4, 5) sur ses côtés supérieur et inférieur, la rainure supérieure (4) et la rainure inférieure (5) s'étendant à une distance (a) l'une de l'autre dans le plan de la plaque (PE) de façon à former une bande de rupture (6). La plaque de départ (1) est ensuite sectionnée le long de cette bande de rupture (6) de telle sorte que des languettes longitudinales faisant saillie le long des côtés longitudinaux (11, 12) subsistent et soient utilisées pour former les languettes de verrouillage (15, 16).
