A device for opening a packing bag 25 folded flat comprising means for blowing air 34 in the direction of the end mouth 26 of the bag 25, and a pinching device 38 adapted to be able to pinch at a distance from the end mouth 26 an entire width of the end section of the folded bag, said end section being at least substantially impermeable to gas flows. This ensures the opening of the end mouth 26 under the effect of blowing means 34 regardless of the gas-permeability characteristics of the walls of the bag extending beyond the said end section. |
