ABSTRACT OF THE DISCLOSURE Apparatus to seal the valve of a valve bag with adhesive and of the kind where bag arrives from bagging machine standing up or somewhat reclining. The apparatus comprises adhesive sprayer over which and fitted thereto a shield with bow- shaped cross-section and rounded front is mounted so that the fronts of shield and sprayer are flush over and under each other, or so that the shield protrudes in front of sprayer. The assembly comprising shield and sprayer is suspended or has organs to move it in a way that the assembly during insertion into the valve describes a bow- shaped motion in the vertical middle of the bag valve and so that the assembly lifts up the valve when inserted. The adhesive sprayer is designed to apply adhesive onto the lower inside of the bag valve. The apparatus ensures that the adhesive sprayer is properly inserted into the valve as the valve is opened and distended by the shield prior to the process, and in addition the sprayer will be placed at exactly the same spot every time it enters a valve due to its being fixed to the guiding shield.
