Abstract
An automatic form-and-fill packaging machine especially adapted for the ultrasonic sealing of food products in flexible bags from ultrasonically sealable flexible packaging material, and a method to utilize said machine. A packaging machine is provided with a first ultrasonic back seal forming unit for producing a continuous longitudinal back seal on the bag, and a second ultrasonic sealing unit provided in a pair of jaw members which are adapted to form the end seals of the bag perpendicular to the direction of travel of the packaging material. The second ultrasonic sealing unit is provided with a horn and an anvil in opposing jaw members, such that when the jaws are shut, the flexible packaging material is tensioned against sealing land areas to provide the end seals.
