Abstract (en)
[origin: ES8704571A1] A method for seaming the ends of a papermaker's fabric during installation on papermaking equipment is disclosed. The method comprising the steps of: providing a base fabric having a batt needled thereto such that one end of the batt extends beyond the corresponding end of the base fabric to overlap the opposing end of the batt when the ends of the base fabric are joined joining the base fabric to form a continuous belt overlapping the extended end of the batt upon its opposite end cutting the overlapping batt ends across the width of the fabric such that the opposing batt ends are configured to complement each other combing each of the complementary batt ends such that the fiber dispersion of the batt material is decreased and the ends of the batt are lengthened overlapping the combed batt ends and needling the overlapping combed batt ends together and to the base fabric such that the batt material of each end of the batt is interdispersed with each other and the resultant material is essentially the same as the remainder of the fiber batt.
Abstract (fr)
La présente invention permet notamment d'utiliser des feutres de papeterie à jonction, qui sont beaucoup plus commodes à installer, même dans des cas ou une feuille de papier ou analogue portée par ce feutre au cours de sa fabrication risque particulièrement d'être marqué par la jonction. Elle prévoit un aiguilletage final d'une zone de raccordement de nappe (ZR) sur une longueur suffisante pour assurer la continuité de la nappe souple (42) au voisinage de la ligne de raccordement des canevas plus raides. Application à la fabrication de papier, carton et ouate.
