Abstract
Method and apparatus for forming, filling and sealing bags from a continuous supply of bagging material, the apparatus including a pair of sealing jaws transversely movable toward each other to engage the bagging material to form a transverse seal providing the top closure for a filled bag and the bottom closure for a succeeding bag. The improvement includes stretch assemblies attached to the sealing jaws and engageable with the bagging material at opposite edges thereof to provide opposing forces in directions perpendicular to the movement of the sealing jaws to flatten the bag and remove any wrinkles therefrom prior to sealing of the bags by the sealing jaws.
