Fuente: WIPO "tomato" There is described a sealing anvil device (28) comprising a main structure (35) having an engagement surface (36) extending along a longitudinal axis (A) and being configured to engage a tube (4) filled with a pourable product for compressing the tube (4) along a transversal portion, the sealing anvil device (28) further comprising a carrier device (37) carrying the main structure (35) A center portion (38) of the main structure (35) is angularly moveably coupled to a coupling group (39) of the carrier device (37) such that the main structure (35) is angularly moveable about a rotation axis (B). The rotation axis (B) is transversal to the longitudinal axis (A).
