ABSTRACT:
An improved bagging machine for the packaging of powdered materials is provided which avoids soiling the lips of the bags with material which would interfere with the sealing of the bags. The bagging machine comprises a station for gripping and opening the bags having suckers connected to a vacuum source, a filling station including a product inlet chute connected to a measuring means, means for opening and closing the orifice of the chute and for inserting this orifice into the open mouth of the bags and for applying the lips of the latter sealingly against the chute. Means are provided for compacting the material and means for sucking out the air contained inside the bags being filled, a station for closing the bags by welding and/or sewing, means for holding the bags by suspension and for transferring them from one station to the next, and means for synchronizing and sequencing the various movements and operations are also provided. The bagging machine is particularly useful for the automatic filling of bags with powdered materials.
