The invention relates to a product stacking device for forming product stacks (-) of product groups (-) consisting of products (-), which lie flatly and/or are brought into a shingled product arrangement (-), during a transportation movement (-). The product stacking device includes at least two stack contact surfaces (-), which are provided in order to form the product stack (-) by reducing a spacing (-) between the stack contact surfaces (-), the stack contact surfaces lying opposite one another in a product group direction (-).

Product stacking device

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 () which are parallel to each other and at least two sealing jaw pairs (and) which are each formed by at least one sealing jaw () rotating around the first rotation axis () and at least one sealing jaw () rotating around the second rotation axis (), such that, during a sealing process, the sealing jaws () of a sealing jaw pair () approach each other and material layers can be sealed between the sealing jaws () 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 (pairand pair) independently of each other.
