Title
(EN) RING-LIKE ELASTIC BELT WITH IMPROVED SIDE SEAMS
(FR) CEINTURE ÉLASTIQUE ANNULAIRE DOTÉE DE COUTURES LATÉRALES AMÉLIORÉES
Abstract
(EN)
Disclosed is a ring-like elastic belt (104) having a longitudinal direction and a lateral direction comprising: a pair of side seams which join the lateral edges of the front belt (106) and the back belt (108) such that the front fold over (162FO) and the back fold over (162FO) cooperatively define a distal edge of the ring-like elastic belt (104), the side seam made by a hot air bond which at least partially melts material of the elastic laminate, the side seam having continuity of the melted material along the substantial entirety of its longitudinal dimension; wherein the side seam has a Belt Minimum Peel Strength of at least about 6N/25mm, a Belt Maximum Peel Strength of no more than 18N/25mm, and a Top Bottom Difference of no more than 15%, according to the measurements herein. Also disclosed is a method of manufacturing a ring-like elastic belt (104) comprising the steps of: intermittently seaming an assembly of substrates by compressing a melted portion between an outer circumferential surface (370) of an anvil roll (368) and a pressing member (380); wherein the outer circumferential surface of the anvil roll comprises a grooved region (370G) and a flat region (370F) wherein the continuous fold over (466FO) region is configured to meet the grooved region (370G) of the anvil roll upon compression. Also disclosed is a method of manufacturing a ring-like elastic belt (104) comprising the steps of: intermittently seaming an assembly of substrates by compressing a melted portion between an outer circumferential surface (370) of an anvil roll (368) and a pressing member (380); wherein the pressing member (380) comprises a regular surface (423) and an indented surface (421), wherein the continuous fold over (466FO) region is configured to meet the indented surface of the pressing member (380).

L'invention concerne une ceinture élastique annulaire (104) ayant une direction longitudinale et une direction latérale comprenant : une paire de coutures latérales qui relient les bords latéraux de la ceinture avant (106) et de la ceinture arrière (108) de telle sorte que le pli avant (162FO) et le pli arrière (162FO) définissent de manière coopérative un bord distal de la ceinture élastique annulaire (104), la couture latérale réalisée par une liaison à air chaud qui fait fondre au moins partiellement le matériau du stratifié élastique, la couture latérale ayant une continuité du matériau fondu le long d'essentiellement la totalité de sa dimension longitudinale; la couture latérale ayant une résistance au décollement minimale de ceinture d'au moins environ 6N/25 mm, une résistance au décollement maximale de ceinture qui n'est pas supérieure à 18N/25 mm, et une différence haut bas qui n'est pas supérieure à 15 %, selon les mesures de l'invention. L'invention concerne également une méthode de fabrication d'une ceinture élastique annulaire (104) comprenant les étapes consistant à : sertir par intermittence un ensemble de substrats par compression d'une partie fondue entre une surface circonférentielle externe (370) d'un contre-cylindre (368) et un élément de pression (380); la surface circonférentielle externe du contre-cylindre comprenant une région rainurée (370G) et une région plate (370F), la région de pli continu (466FO) étant configurée pour rencontrer la région rainurée (370G) du contre-cylindre lors de la compression. L'invention concerne également une méthode de fabrication d'une ceinture élastique annulaire (104) comprenant les étapes consistant à : sertir par intermittence un ensemble de substrats par compression d'une partie fondue entre une surface circonférentielle externe (370) d'un contre-cylindre (368) et un élément de pression (380); l'élément de pression (380) comprenant une surface régulière (423) et une surface dentée (421), la région de pli continu (466FO) étant configurée pour rencontrer la surface dentée de l'élément de pression (380).
