Abstract

La présente invention aborde le problème de la mise à disposition d'un procédé de fabrication d'une ailette d'échangeur de chaleur selon lequel des corps semblables à une courroie métallique ayant une largeur du produit ne sont pas emmêlés les uns avec les autres même lorsque les corps semblables à une courroie métallique ayant la largeur du produit s'affaissent vers le bas et sont fournis de manière intermittente. Comme solution, ce procédé de fabrication d'une ailette d'échangeur de chaleur comprend : une étape consistant à former un corps semblable à une courroie métallique (48) ; une étape consistant à former des corps semblables à une courroie métallique (49) ayant une largeur du produit au moyen d'un dispositif à fente entre rangées (52) et à extraire les corps semblables à une courroie métallique (49) ayant la largeur du produit au moyen d'un premier dispositif d'alimentation (50) ; une étape consistant à amener les corps semblables à une courroie métallique (49) ayant la largeur du produit dans un dispositif de coupe (60) au moyen d'un second dispositif d'alimentation (62) après avoir provoqué l'affaissement vers le bas des corps semblables à une courroie métallique (49) ayant la largeur du produit ; et une étape consistant à former une ailette d'échangeur de chaleur (30) par découpe de chaque corps semblable à une courroie métallique (49) ayant la largeur du produit selon une longueur prédéterminée par le dispositif de coupe (60), les longueurs des corps semblables à une courroie métallique (49) ayant la largeur du produit entre le dispositif à fente entre rangées (52) et le dispositif de coupe (60) étant prédéterminées de façon à être différentes entre les corps adjacents semblables à une courroie métallique (49) ayant la largeur du produit.
