Abstract

PURPOSE: To perform seam welding of bags easily without increasing the size of a device by a method wherein when bags produced by a bag-making machine are sequentially stacked on a table, each predetermined number of the bags are pierced by heatd needles to weld them together.
CONSTITUTION: The heated needles 20 are projected above the upper surface of a receiving plate 16, and a solenoid valve for operating a vertically reciprocating mechanism 21 is actuated to lower the needles 20. A bag blank strip F sequentially fed from the bag-making machine 10 is cut to become a bag B each time a movable blade 15b descends, and simultaneously, the bag B is depressed by a pressing plate 25 and is pierced by the heated needles 20 projecting upwradly above the receiving plate 16. The bags thus pierced orderly and sequentially and stacked are welded to each other at the peripheries of holes 30 by the outside peripheral surfaces of the heated needles 20. Accordingly, the seam welding device is simple, and a bag-making machine capable of effectively utilizing thermal energy because of little radiation of heat from a welding member can be obtained.
