Description of the Related Art When packaging snacks such as potato chips with a vertical bag-filling and packaging machine, they may be piled up high so that they may be caught in a horizontal heater. It was provided. The conventional ironing device is one in which a pair of ironing rods are provided below the horizontal heater so as to project from the heater block beyond the heater surface.The horizontal heater locally seals the packaging cylinder to drop snacks into the packaging cylinder. After filling, close the pair of ironing bars so as to secure a gap of about 10 mm and lower them (lower the heater block), and the snacks accumulated in the squeezed portion of the packaging cylinder will sink into the horizontal heater. When the snacks that had accumulated at the bite-in position sank, horizontal sealing was performed and the packaging speed could not be increased.
