发明名称 Bag-filling apparatus
摘要 Bag-filling apparatus comprises gripping means for gripping flat bags adjacent to their top edges and side edges, vacuum cups for engaging the bag on opposite sides near its top edges and for pulling said top edges apart, and a filling pipe, which is provided with filling hopper halves, which are adapted to be pivotally movable about parallel axes by drive means. The filling hopper halves are hinged on respective axes which are transverse to the line which connects the grippers and the spreading members of the filling hopper halves have in cross-section laterally inverted, outwardly protruding or convex shapes the apices of which are disposed on the line which connects the grippers. The arrangement may be such that the end edges and side walls of the filling hopper halves are in sealing contact with each other when the filling hopper halves are in their swung-in position.
