A conveyor delivers a series of cylindrical wrapped fibrous modules to a station where the module is lifted off the conveyor and an operation conducted on the module. One operation is to find a tail, or unattached segment, of the cover. Another operation is to remove the cover, by slitting and then unwinding it. The cover is delivered to a storage area and the contents of the module are delivered into a hopper, or in some embodiments, into a disperser. In some embodiments, a grabber moves the slit cover from adjacent a slitting position to a storage area and includes a guide wheel for moving a conveyor up and down in response to the configuration of the round module. In one embodiments, the plastic cover is removed manually by workers guiding the plastic wrap as it is unrolled by the unrolling device.
