摘要： 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).
