Abstract

Bags with welded edges are created by a vertical tubular bagging machine. The bags are flat on top and are relatively wide at the bottom. Only one edge-welding device to create a top seam is provided on one side of the fill pipe. Two edge-welding devices on the opposite side of the fill pipe are used to create two bottom seams stabilizing the bag.
