ABSTRACT:
Front end portions of respective bands drawn out of two band reels are guided in substantially parallel relationship by means of band guide 11. When the band reel in use becomes empty, band feeding unit 30 is driven in reverse to thereby discharge a rear end portion of the band and, further, a front end portion of other band in stand-by condition is moved to a position of use by means of band changeover unit 20. An automatic band charging device can be provided which enables rapidly replacing an empty band reel with a spare band reel and which has a simple structure and realizes a reduced number of constituent parts, thereby contributing to the miniaturization of the packing machine.
