The problem is solved by using a mechanical fly bars to restrain the flaps of an insert while moving a bundle on a conveyor. The insert can be any material that provides structural protection to the bundle during stacking. ## Claims ### Claim 1 An apparatus for transporting a bundle having an insert with flaps to provide structural integrity to the bundle while mechanically restraining the flaps of the insert while moving the bundle on a conveyor comprising, means for moving the bundle wherein the flaps of an insert are mechanically restrained., means for transporting the bundle onto a film wrapping conveyor while restraining the movement of the flaps, and means for film wrapping the bundle while on said film wrapping conveyor. ### Claim 2 (depends on 1) An apparatus according to claim 1 wherein the means for moving the bundle includes pushing the bundle on a dead plate. ### Claim 3 (depends on 2) An apparatus according to claim 2 where in the bundle is pushed by a first fly bar attached to a first fly bar conveyor. ### Claim 4 (depends on 3) An apparatus according to claim 3 wherein a second fly bar attached to a second fly bar conveyor acts together with the first fly bar to restrain the movement of the flaps while the bundle is being moved. ### Claim 5 (depends on 4) An apparatus according to claim 4 wherein the film wrapping conveyor has buckets to receive the bundle and to restrain the movements of the flaps. ### Claim 6 (depends on 5) An apparatus according to claim 5 where the means for film wrapping includes a film threaded over the bucket and for providing a plane of film so that the bundle pushes into the plane causing the film to cover the bundle. ### Claim 7 (depends on 6) An apparatus according to claim 6 wherein a sealing bar heat seals the film around the bundle and cuts the film to maintain the plane of the film so that the next bundle can be wrapped. ### Claim 8 (depends on 7) An apparatus according to claim 7 including means for stopping the bucket conveyor when the first and second fly bar release the bundle and the bucket is positioned under the bundle. ### Claim 9 (depends on 8) An apparatus according to claim 8 including means for stopping the fly bar conveyors after the first and second fly bars clear the height of the bundle ### Claim 10 (depends on 9) An apparatus according to claim 9 including means for moving a bundle between a another pair of fly bars while the fly bar conveyors are stopped. ### Claim 11 A process for transporting a bundle having an insert with flaps to provide structural integrity to the bundle while mechanically restraining the flaps of the insert while moving the bundle on a conveyor comprising, moving the bundle wherein the flaps of an insert are mechanically restrained., transporting the bundle onto a film wrapping conveyor while restraining the movement of the flaps, and film wrapping the bundle while on said film wrapping conveyor. ### Claim 12 (depends on 11) A process according to claim 11 wherein moving the bundle includes pushing the bundle on a dead plate. ### Claim 13 (depends on 12) A process of according to claim 12 where a first fly bar attached to a first fly bar conveyor pushes the bundle. ### Claim 14 (depends on 13) A process according to claim 13 includes restraining the flaps of the moving bundle by using a second fly bar attached to a second fly bar conveyor. ### Claim 15 (depends on 14) A process according to claim 14, including providing a film wrapping conveyor having buckets to receive the bundle and to restrain the movements of the flaps. ### Claim 16 (depends on 15) A process according to claim 15 including threading the heat shrink film over the bucket so that the bundle can be placed in bucket and rest on the film. ### Claim 17 A process according to 16 including providing a plane of film and pushing the bundle into the plane causing the film to cover the bundle. ### Claim 18 (depends on 17) A process according to claim 17 including stopping the bucket conveyor when a bucket is positioned to receive a bundle being released by the first and second fly bars. ### Claim 19 (depends on 18) A process according to claim 18 including stopping the fly bar conveyors after the first and second fly bars clear the height of the bundle. ### Claim 20 (depends on 19) A process according to claim 19 including moving a bundle between another pair of fly bars when the fly bar conveyors are stopped.
