Les fils longitudinaux sont acheminés (29), soumis à un avancement (20) et à un dressage (17) suivis d'une mesure de la longueur (7) et de la coupe (4) à la longueur désirée. Ainsi, les fils (1) sont acheminés à des positions de gaines (19) sur un dispositif d'alimentation approprié (2) pour des fils longitudinaux (1), lesquelles positions (19) correspondent à des emplacements des fils longitudinaux (1) dans le treillis (5) qu'il s'agit de produire ; de plus, les fils longitudinaux (1) sont transférés à partir du dispositif d'alimentation (2) et introduits dans une ligne de soudage appropriée (6) dans laquelle la production du treillis (5) s'effectue. Pendant la production du treillis (5), le dispositif d'alimentation (2) pour fils longitudinaux (1) peut revenir à sa position de remplissage pour être de nouveau regarni de fils longitudinaux (1) pour le prochain treillis (5) à produire.
