ABSTRACT:
A bagging machine comprising a bag supply device, a bag-opening device, a bag-sealing device mounted on one side of the bag-opening device, and a bag-moving device. The bag supply device includes a mounting member and a first bag-attracting portion mounted to the mounting member that reciprocates between a bag supply position and a bag opening position. The bag-opening device has a second bag-attracting portion which faces the first bag-attracting portion when the mounting member of the bag supply device is in the bag opening position. The second bag-opening portion can move toward and away from the first bag-attracting portion. The bag-moving device has a pair of openable holding members. The holding members reciprocate between the bag-opening device and the bag-sealing device, and close the opening of a bag by holding the opening between themselves.
