Abstract
An apparatus for manufacturing a circular bag is configured with two anvil half-sections that are movable relative to each other from an open position to a closed position. An ultrasonic sealing tool is provided that is movable towards and away from the anvil half-sections and configured to seal a lid portion to a sleeve portion of the circular bag. In the closed position, the anvil half-sections define an interior space which is at least as large as the exterior circumference of the circular bag to be manufactured.
