The picking band wheel is made of a hub and two wheel discs. Each disc is provided with pocket-like spoke parts which have transverse walls at the bottom which abut the transverse walls of the other disc on a common connecting plane disposed substantially perpendicularly to the axis of rotation of the wheel. The front disc has a conical end wall in which the pocket-like spoke parts are formed so that an alternating spoke pattern is formed. The back disc has a flat end wall. |
