Abstract
The present invention provides, in various embodiments, a rotary-type machine (M) for continuously sealing individual foil bags (B) by way of ultrasonic welding between an anvil (6) and a sonotrode (5) in at least one welding station (S) of a carousel (1), where each foil bag (B) can be positioned by way of holders (11). In some embodiments, the rotary-type machine (M) comprises at least one welding station (S) composed of a sonotrode (5) being located stationary at least relative to the direction of circulation (8) and anvils (6) which with intermediate spacings (7) rotate past said sonotrode (5) successively in the direction of circulation (8) of the carousel (1). According to the invention, the foil bags (B) are sealed at the stationary sonotrode (5) when the anvils (6) equipped with the foil bags (B) are rotated past.
