将至少两个幅材料接合在一起的接缝
摘要：
通过超声熔接、热结合等将至少两个幅材料以重叠方式以结合图案(4)接合的一种接缝，所述结合图案(4)包括沿着并邻近所述重叠部分的至少一个侧边缘(1a，2a)的至少一部分以纵向延伸的第一结合图案(5)以及至少一个第二结合图案(6)。第二结合图案(6)的结合面积占据第一和第二结合图案总结合面积的30％以上。第一结合图案(5)的结合元件(5a)的平均面积为第二结合图案(6)的结合元件(6a)的平均面积的至少2倍。从接缝横向上看，结合图案(4)的接触面积为结合图案(4)在沿结合图案长度的任何指定点处宽度(w)的10～30％。
摘要（英）：

A seam joining together at least two web materials in an overlapped manner by ultrasonic welding, heat bonding or the like, in a bonding pattern (4) comprising a first bonding pattern (5) and at least one second bonding pattern (6) extending in longitudinal direction along and adjacent at least one side edge (1a, 2a) of the overlapped portion. The bonded area of the second bonding pattern (6) occupies more than 30 % of the combined bonded area of the first and second bonding patterns. The bonding elements (5a) of the first bonding pattern (5) have a mean area that is at least 2 times the meanarea of the bonding elements (6a) of the second bonding pattern (6). The contact area of the bonding pattern (4), as seen in transverse direction of the seam, is between 10 and 30% of the width (w) of the bonding pattern (4) at any given point along the length of the bonding pattern.
