Abstract
A circular textile fiber bale opener with a goosenecked transition from separately chambered dual plucker rolls provide for larger laydown area and greater production. The transition causes uniform air velocity at the top of the fiber bales across the full length of the plucker rolls. Plucked fibers from the transition are delivered through a centrally disposed hollow shaft for delivery downstream. The shaft carries electrical collector rings with which are associated brushes which rotate with the opener for completing connections between the external and internal wiring required for the apparatus.
