A continuous bag sealing machine for heat sealable bags is provided. The machine includes a conveyor belt upon which the bag to be sealed is moved. The upper portion of the bag is gripped by a double pair of "V" belts and is moved through the machine to a hot air nozzle which fuses and seals the top of the bag. As the bag is heated, it is simultaneously stretched to more securely fuse the bag together. A cool air nozzle hardens the seal and a cutting device cuts off the top of the bag. One pair of "V" belts transport the cut-off scrap of the bag out of the device. |
