摘要：Apparatus for filling with loose material bags (1,1a,1b) having a mouth (1a)extending in a direction of width (L), comprising: - grippers (112,112a) for gripping

opposite sides (1b) of the bag, which are arranged opposite each other relative to avertical axis (Z-Z) of symmetry and movable symmetrically towards/away from each otherwith respect to said axis in a direction (Y-Y; X-X) parallel to that of the direction of width(L) of the bag; - suction cups (113) for gripping the side portions of the bag and movablesymmetrically towards/away from each other along a direction (X-X;Y-Y) perpendicular tothe direction of width (L) of the bag for opening/gripping the mouth (1a) of the bag (1), -valves (301) rotating from a closing position outside the bag into an opening positioninside the mouth (1a) of the bag (1), comprising: a pair of first carriages (210) arrangedopposite each other and movable, in the direction (Y-Y;X-X) of width (L) of the bag (1)symmetrically with respect to the vertical central axis (Z-Z) of symmetry, from aminimum/maximum spaced position to a maximum/minimum spaced position, the

following being fixed to each first carriage (210): - a flange (215) extending in the directionof width (L) of the bag towards the axis of symmetry (Z-Z) and designed to form anadjustable stop surface for end-of-travel of rotation for opening and entry into themouth of the bag of the valves (301) of the bag-holder device, - said grippers (112;112a)for gripping the opposite edges of the bag, and the relative distance with respect to theaxis of symmetry (Z-Z) between the end-of-travel flanges and the gripping grippersbeing constant and independent of the width of the bag, the movements for positioningof the two first carriages (210), the flanges (115) for end-of-travel of rotation of thevalves (301) and the grippers (112,112a) for gripping the edges (1b) of the bag (1) beingcoordinated and performed by means of a single start-of-cycle command depending onwidthwise dimension (L) of the bag (1).
