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.
A rotary-type machine comprising a rotary-type filler for continuously sealing individual foil bags by way of ultrasonic welding between an anvil and a sonotrode in at least one welding station associated with a rotationally driven carousel, wherein each foil bag can during circulation be positioned by way of holders, wherein said rotary-type machine has at least one welding station comprising a sonotrode positioned stationary relative to a direction of circulation of said carousel, and anvils which are with intermediate spacings rotatable past said sonotrode successively in the direction of circulation of said carousel and on which said foil bags are positioned;
A method for continuously sealing individual foil bags in a carousel of a rotary-type machine by way of ultrasonic welding between a sonotrode and an anvil in at least one welding station associated with said carousel, wherein a number of successively positioned anvils, on each of which a foil bag is positioned, corresponding to the number of foil bags in said carousel is in a direction of circulation of said carousel with intermediate spacings rotated past a sonotrode of at least one welding station positioned stationary relative to the direction of rotation, said foil bags thereby being sealed;
