Claim:
1. A horizontal transverse sealing station for a horizontal tubular bag machine ( 12 a ; 12 b ), for producing transverse sealing seams ( 14 a ; 14 b ) on at least one film tube ( 18 a ; 18 b ) transported in a continuous, at least substantially horizontal transport direction ( 16 a ; 16 b ), the horizontal transverse sealing station comprising a transverse sealing station base ( 20 a ; 20 b ), which is fixedly connected to the tubular bag machine ( 22 a ; 22 b ), the transverse sealing station base ( 20 a , 20 b ) including a transverse sealing unit ( 24 a ; 24 b ) having at least one sealing jaw pair ( 28 a ; 28 b ), which is movably mounted on the transverse sealing unit ( 24 a ; 24 b ) and is formed by two sealing jaws ( 26 a ; 26 b ) and the sealing surfaces ( 30 a ; 30 b ) of which, during a sealing process, come closer together in a sealing movement ( 32 a ; 32 b ) having relative to the transverse sealing unit ( 24 a ; 24 b ) at least one movement component ( 34 a ; 34 b ) in the transport direction ( 16 a ; 16 b ), in order to seal material layers ( 36 a ; 36 b ) of the film tube ( 18 a ; 18 b ) between the sealing surfaces ( 30 a ; 30 b ), under the application of at least one of heat and pressure, and to move said material surfaces apart again at the end of the sealing process, wherein the transverse sealing station base ( 20 a , 20 b ) also includes a mass compensating unit ( 42 a , 42 b ) having at least one drivably mounted compensating mass ( 44 a , 44 b ), characterized in that the transverse sealing unit ( 24 a ; 24 b ) is mounted drivably on the transverse sealing station base ( 20 a ; 20 b ) with a displacement movement ( 38 a ; 38 b ) at least substantially parallel to the transport direction ( 16 a ; 16 b ), wherein the at least one drivably mounted compensating mass ( 44 a , 44 b ), which, in a compensation movement ( 46 a , 46 b ) comprises at least one movement component ( 48 a , 48 b ) that is parallel to the displacement movement ( 38 a , 38 b ) and is driven such that the inertial forces induced by the displacement movement ( 38 a , 38 b ) and those induced by the compensation movement ( 46 a , 46 b ) are at least partially eliminated.
