An anvil for forming a transversal sealing of a sleeve-shaped portion of packaging material holding a liquid product, said anvil comprising a main surface, in operation, facing the tube, and a ridge provided on the main surface, the ridge comprising a first section and a second section, wherein the first section of the ridge is placed below the second section such that, in operation, a stress in the packaging material formed by a hydrostatic pressure formed by the liquid product is shifted from a first part of the sleeve-shaped portion placed above the first section of the ridge to a second part placed above the second section.

Anvil, a transversal sealing system, filling machines, and a method for producing packages

An ultrasonic sealing device including a sonotrode for sealing a packaging material, including a piezoelectric transducer to generate ultrasonic acoustic vibrations for the sealing, a housing, a power circuit connected to the piezoelectric transducer. The power circuit is enclosed in the housing, and an absorbent arranged in the housing to absorb moisture in an atmosphere therein to lower humidity. A method of controlling humidity in an ultrasonic sealing device is also described.

Ultrasonic sealing device

An assembly for producing sealed packaging units () from a sheet packaging material, comprises: an advancement device () for advancing the sheet packaging material along an advancement direction (F), a longitudinal sealing device for sealing opposite borders of the sheet packaging material along a longitudinal sealing band arranged parallelly to the advancement direction (F), thereby forming a continuous tube (), a transverse sealing device () for sealing the continuous tube () transversely to the advancement direction (F), so as to define a sealed packaging unit (). The transverse sealing device () comprises a sealing element () and an abutment element () that are intended to mutually cooperate during sealing while being located on opposite sides of the continuous tube (). The sealing element () is so configured as to act on a side () of the continuous tube () on which the longitudinal sealing band is provided.

Assembly for producing sealed packaging units

An anvil for transversally sealing a tube having a longitudinal seam portion can include a first elongate contact surface and a second elongate contact surface. In some embodiments, the first elongate contact surface includes a first groove and the second elongate contact surface includes a second groove, each one of the first groove and the second groove being adapted to receive, in use, a respective section of the longitudinal seam portion of the tube. The first elongate contact surface can include a first seam interaction portion positioned within the first groove and having a first surface profile. The second elongate contact surface can include a second seam interaction portion positioned within the second groove and having a second surface profile. In some embodiments, the first surface profile differs from the second surface profile.
