ABSTRACT:
A sealing apparatus includes an anvil of a sealing abutment surface, which is driven to circulate with a constant peripheral velocity, and an ultrasonic horn of a sealing abutment surface, which is driven to reciprocate with varying velocities. Since the relative velocity of a soft workpiece moving along with the anvil against the sealing abutment surface of the ultrasonic horn can be made low, a sealing energy from the ultrasonic horn may be applied to the soft workpiece sufficiently long.
