Diese Kombination ist derart in vertikaler Richtung zweigeteilt, dass jeweils eine Formschulterhälfte und eine Füllrohrhälfte eine Baueinheit bilden. Die beiden Baueinheiten können relativ zueinander in horizontaler Richtung versetzt werden, um Beutel unterschiedlicher Breite herstellen zu können.From the US 32 96 770 Such a bagging machine according to the preamble of claim 1 is known, which has a two-part combination of a forming shoulder and a nozzle connected to the forming shoulder of a filling tube. This combination is split into two in the vertical direction such that in each case one forming shoulder half and one filling tube half form a structural unit. The two units can be offset relative to each other in the horizontal direction to produce bags of different widths.

Aus der DE 26 09 168 C3 ist bekannt, einen elektrischen Linearmotor im Verpackungsmaschinenbau einzusetzen. Dieser Antrieb wird dazu genutzt, einen Auslauftrichter für Füllgut parallel zu versetzen.From the DE 26 09 168 C3 It is known to use a linear electric motor in packaging machinery. This drive is used to parallelize a discharge hopper for filling material.

Die US 5,127,212 offenbart ein vertikal geteiltes Füllrohr einer Verpackungsmaschine. Dabei kann der Querschnitt des Füllrohres in horizontaler Richtung auf die Größe abzupackender Gegenstände eingestellt werden. Die Gegenstände fallen durch das Füllrohr in einen unterhalb des Füllrohres kopfseitig offen gehaltenen Beutel.The US 5,127,212 discloses a vertically divided filling tube of a packaging machine. In this case, the cross section of the filling tube can be adjusted in the horizontal direction to the size of auszupackender objects. The objects fall through the filling tube into a bag which is kept open on the head side below the filling tube.
