摘要：
A method of bonding a first web of material to a second web of material to form a composite material is disclosed herein. First, a first web of material and a second web of material moving in a machine direction is provided. The webs of material pass over a first energy application device extending transverse in the cross-machine direction. The first energy application device includes a primary bonding pattern and a secondary bonding pattern. The primary bonding pattern in combination with the secondary bonding pattern extends continuously across the first energy application device in the cross-machine direction. In addition, a second energy application device is provided. The second energy application device is moved in the cross-machine direction, and thereby extending the second energy application device over the first energy application device and operating the first and second energy application devices in combination to bond a composite web.
