Abstract (en)
[origin: WO9965774A1] A bag filling machine having gusset pleat gripping assemblies on opposite sides of the filling spout. Each of the assemblies has a pair of cooperatively actuable gusset gripping members (92a, 92b, 98a, 98b) operable to selectively grip each of the two gusset pleats on opposite sides of a gusseted bag and to pull those pleats apart to fully open position to increase the material-receiving area of the bag mouth. A gusset tucker (112a, 112b) is also utilized on each side of the spout to move inwardly to engage the fold between the two gusset pleats as the bag top is flattened to a closed position. An improved cylinder structure (70a, 72a) and gusset wedge apparatus (180, 182) are used to function together to increase the reliability of the placement of the bags upon the spout of the bag filling machine at the start of the bag filling cycle.
