Abstract
Abstract An ultrasonic seaming apparatus in which rotatable anvil disks driven in unison engage one side of a flexible workpiece whose other side is contacted by a resonant horn. Means are provided for independently mounting each anvil disk and adjusting the bias which urges each disk toward the horn. Also, the minimum gap between each anvil disk and the horn is selectively adjustable.
