Abstract
An unloader for a cotton compacting structure such as a module builder, including loose cotton retaining apparatus configured and operable for retaining loose cotton carried from, and returning the loose cotton to, the compacting structure. Apparatus of the invention can include an array or arrays of individual upstanding filaments, or flaps, located on a cotton conveying surface of a door arrangement or ramp extending from the compacting structure and over which a mass of compacted cotton or module is unloaded. The apparatus is configured to allow passage of a mass or module of compacted cotton thereover, while preventing passage of at least a substantial portion of any loose cotton following the mass or module along the surface. The apparatus is also configured for returning the loose cotton to the compacting structure upon folding or closing of the door or ramp.
