There is provided a method of manufacturing a string of bags from a hose-like blank. The blank is cut along a wave-shape line substantially centrally between two opposed long edges of the blank, to form two blank-halves. Welds are made adjacent selected wave-tops and wave-bottoms of the wave-shape line to form bag handles, and further welds are made perpendicularly to said wave-shape line at selected distances apart to form said string of bags. Separation lines are made adjacent said further welds to bundle a bag to be separated from the string of bags thus formed. |
