Abstract
This invention is directed to a fiber blending machine which takes amounts of fiber from a plurality of bales to provide a uniform blend of fibers. The machine is provided with an automatic apparatus to apply pressure to the top of nearly exhausted bales to ensure that fibers are plucked therefrom as they are reciprocated back and forth across the plucking area of the machine.
