  • Horizontal transverse sealing unit
    Patent number: 9266636
    Abstract: The invention relates to a horizontal transverse sealing unit, in particular for a horizontal tubular bag machine for sealing at least one tubular film around at least one object to be packaged, having a first and a second rotational axis (18a, 20a) which are parallel to each other and at least two sealing jaw pairs (26a, 28a and 30a, 32a) which are each formed by at least one sealing jaw (26a, 30a) rotating around the first rotation axis (18a) and at least one sealing jaw (28a, 32a) rotating around the second rotation axis (20a), such that, during a sealing process, the sealing jaws (26a, 28a) of a sealing jaw pair (26a, 28a) approach each other and material layers can be sealed between the sealing jaws (26a, 28a) under exertion of pressure. According to the invention, at least two independently drivable sealing drives of the horizontal transverse sealing unit are provided to drive at least two sealing jaw pairs (pair 26a, 28a and pair 30a, 32a) independently of each other.
