| The Vario-Seal bag sealing machine |
 |
Mode of Operation A case / tray / crate with a filled bag is fed to the motor driven infeed belt conveyor section of the Vario-Seal where it is held back by a stop gate until the case in the bag sealing position has had its filled bag sealed. There are two stop gates inside the machine. When the bag has been sealed, the second stop gate drops to let the case move out towards the case closing machine. Then the first stop gate is dropped, allowing the next case into the bag sealing position where it is held by the second stop gate and the bag sealing cycle begins. When the case / tray / crate is in position,it is lifted up towards the bag sealing assembly. The filled bag is now stretched horizontally to the acceptable limit presenting only two layers of film for sealing. The sealing bars are moved against the tightly held top side of the bag and then seal it. The bag is released and the tray lowered after which it exists the machine. Maximum speed for standard Vario-Seal is 10 cases / trays per minute. |
