Abstract
A form-fill-seal machine has an ultrasonic vibration emitter head positioned outside the tube being formed by the overlapping of the margins and of a film web, and an anvil positioned inside the tube defined by those margins, the anvil being mounted on an anvil carrier which is supported by a frame element entirely independent of the forming box used to fold the film, so as to isolate the anvil from vibrations sustained from the forming box. The anvil carrier can be mounted directly to a carrier body for the ultrasonic vibration emitter, and preferably has the shape of an inverted letter J where the anvil is positioned near the toe of the J, the mounting to the sealing machine frame is at the top of the stem of the J, with a slot between the toe and the stem
