1. Field of the Invention
This invention is directed to polymer film bag-handling apparatus, and particularly a vacuum conveyor which can advance the bag to a work station and release the bag at the work station for further bag operations or handling.
2. Description of the Prior Art
Common bag-making machines are supplied with polymer film which is then folded, sealed, and/or cut to provide a bag of the desired size and shape. Such bag-making machines act continually on the polymer film and intermittently deliver bags. These bags are usually stored until the next operation, which may be bag-filling and sealing. Often, the storage is on wickets so that a wicketer receives the cut bags from the bag-making machine.
It is desirable to be able to conveniently handle the bags as they are continually delivered from the bag-making machine. While the bag may be complete as delivered from the bag-making machine, in the sense that it is in the form of two layers sealed around three edges, further operations may be desirable, and it is thus desirable to be able to transfer the bags from the bag-making machine to post-processing position and equipment.
