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 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.
