Abstract: A system for removing plastic wrapping from round cotton modules includes a gantry having a stationary base located in front of a disperser. A separate conveyor between the gantry and the disperser receives unwrapped round cotton modules from the gantry. Because the gantry is stationary while the disperser digests an upstream module, a gap is created between the upstream module and the module being unwrapped. This gap is closed up when the most recently unwrapped module is placed on the separate conveyor which is driven at a high rate of speed to abut, nor nearly abut, the modules.
