Title (EN) ANVIL FOR TRANSVERSALLY SEALING A TUBE OF PACKAGING MATERIAL AND SEALING JAW HAVING AN ANVIL
(FR) ENCLUME DESTINÉE À SCELLER TRANSVERSALEMENT UN TUBE DE MATÉRIAU D'EMBALLAGE ET MÂCHOIRE D'ÉTANCHÉITÉ PRÉSENTANT UNE ENCLUME
Abstract:
(EN) There is described an anvil (33) for transversally sealing a tube (3) having a longitudinal seam portion (5) and advancing along a path (Q). The anvil (33) comprises a first elongate contact surface (48) and a second elongate contact surface (49). The first elongate contact surface (48) comprises a first groove (51) and the second elongate contact surface (49) comprises a second groove (52), each one of the first groove (51) and the second groove (52) being adapted to receive, in use, a respective section of the longitudinal seam portion (5) of the tube (3). The first elongate contact surface (48) comprises a first seam interaction portion (55) provided within the first groove (51) and having a first surface profile and the second elongate contact surface (49) comprises a second seam interaction portion (56) provided within the second groove (52) and having a second surface profile differing from the first surface profile.
(FR) L'invention concerne une enclume (33) destinée à sceller transversalement un tube (3) présentant une partie de soudure longitudinale (5) et avançant le long d'un trajet (Q). L'enclume (33) comprend une première surface de contact allongée (48) et une seconde surface de contact allongée (49). La première surface de contact allongée (48) comprend une première rainure (51) et la seconde surface de contact allongée (49) comprend une seconde rainure (52), la première rainure (51) et la seconde rainure (52) étant toutes deux conçues pour recevoir, lors de l'utilisation, une section respective de la partie de soudure longitudinale (5) du tube (3). La première surface de contact allongée (48) comprend une première partie d'interaction de soudure (55) disposée au sein de la première rainure (51) et présentant un premier profil de surface, et la seconde surface de contact allongée (49) comprend une seconde partie d'interaction de soudure (56) disposée au sein de la seconde rainure (52) et présentant un second profil de surface différent du premier profil de surface.
