Abstract: Described is a sealing and cutting device for forming bags containing products comprising; a sealing head (1) or sonotrode configured for sealing a portion (2) of a continuous tubular strip (2s), feeding along a feed direction (D2); a counterhead or anvil (3) positioned facing the sonotrode (1); a movement system (4) connected to the sonotrode (1) and/or to the anvil (3) and configured for moving the sonotrode (1) and/or the anvil (3) between a first non-operating position, wherein the sonotrode (1) and the anvil (3) are apart from each other, and a second operating position wherein the sonotrode (1) and the anvil (3) are in frontal contact for sealing the portion (2) of strip of filter material; in such a way as to simultaneously seal a head and a bottom of respective bags to be formed; a cutting element (5) comprising a circular blade 6 connected to a supporting and movement element 8 which is able to impart a translational movement to the blade (6) with a circular shape along a direction (D6) perpendicular to the feed direction (D2) of the continuous tubular strip (2s); the anvil (3) comprises a slit (7) from which the blade 6 protrudes, which is configured for cutting the tubular strip (2s), by contact with the sonotrode (1), whilst the sonotrode (1) and the anvil (3) are in the second operating position, in such a way as to separate a bag formed from the remaining continuous strip (2s).
