ABSTRACT:
Apparatus and method for ultrasonically bonding a web utilizes ultrasonic bonders having respective anvil and sonotrode components which are synchronously orbited with each other and with the rotation of a rotatable drum which carries the web of material to be bonded. One of the anvil and sonotrode components is orbited exteriorly of the drum and the other interiorly of the drum and they are brought into facing alignment through openings in the drum to clamp segments of the material therebetween during passage through a bonding segment of the travel path of the web about the drum. The bonder component orbiting exteriorly of the drum is axially translated away from the anvil along the drum in order to provide clearance for withdrawal of the bonded material from the drum. In this manner, an ultrasonic bonder may clamp the material at a single location for a large segment of its travel along the rotation path of the drum, thereby attaining a bonding time not limited entirely by the travel speed of the web.
