ABSTRACT:
A bag filling and closing apparatus includes a filling station (10) in which the material to be filled in (22) is pushed into a prefabricated bag (24). A device (50, 52, 54, 56) is provided for pulling the bags onto the filling machine as is a device for spreading open and holding the bags. Next to the filling station (10), there is disposed at least one supply and/or intake station (12, 14) for bags, each station being equipped with a device (50, 52, 54, 56) for pulling the bags onto the apparatus. A carriage (30) is movable back and forth between the filling station (10) and the supply and intake station (12, 14) carries the spreading and holding device (28, 30, 44, 46) for the bags. The bags can therefore be picked up and spread open in the supply and intake station (12, 14) and can be transferred to the filling station (10) in that position. Preferably, two supply and intake stations are provided on opposite sides of the filling station (10 ).
