Definitions

  • the present invention relates to a film pulling device and a bag-manufacturing and packaging apparatus having the film pulling device.
  • a bag-manufacturing and packaging apparatus which fills and packages items while manufacturing bags, utilizes as packaging material a film roll, in which an elongated film is wound around a roll core.
  • a film is pulled out as a motor rotates a supporting shaft that supports the film roll.
  • the film is then sent to a bag-manufacturing and packaging portion.
  • the film is severed with a knife at a film joining portion that is furnished at a position apart from the film roll by a predetermined distance.
  • the finished film roll is replaced with a new film roll.
  • a predetermined length of film is pulled out from the new film roll.

  • the length of the unused portion of the film varies depending on the size of bags. Normally, such an unused portion is about the size of three to five bags. The accumulated amount of such unused portions represents a large amount of waste. Furthermore, since such unused portions are discarded, they also cause an increase in the amount of trash, which must be disposed.
  • a purpose of the present invention is to provide a bag-manufacturing and packaging apparatus that allows film rolled in a film roll to be entirely unraveled without having to waste any of the film, and that allows easy replacement of film rolls and easy joining of film.
