containing the same or different kinds of fibers any desired mixing of fibers is accomplished after the fibers are deposited in the hoppers the only function of the hopper feeder being to deliver fibers to the hoppers not to mix them extending between the tracks 10 and 11 is a wheeled frame broadly indicated at 21 and including a rectangularly shaped longitudinally extending carriage 22 having wheels 23 journalled at the ends thereof and rotatably mounted for reciprocal movement along the tracks 10 and 11 the frame 21 supports a pair of transversely space longitudinally extending tracks 24 upon which is mounted for reciprocal movement therealong a wheeled carriage broadly indicated at 25 the carriage 25 supports a fiber plucker or tongs broadly indicated at 26 and comprising a vertically reciprocable support shaft 27 and a pair of cooperating tongs or prongs 30 operatively connected to the lower end of the support shaft 27 the prongs 30 are selectively movable toward and away from each other to close upon a quantity of fibers in a bale within the assembly area and to release the fibers plucked fromthe bale into one of hoppers 17 the sequence of operations may be controlled through a control circuit including a manually operated or computer operated console operatively connected to the electric hydraulic or air motors energizing the movement of the carriage 22 along tracks 10 and 11 carriage 25 along tracks 24 and the raising and lowering the support shaft 27 and the opening and closing of the tongs 30 the console may also include appropriate programming for sensing.
