Bowls

are necessary when you have to automatically or individually guide and feed parts such as: bearings, nails, beads, pins, rivets and screws. The width and the pitch of the internal helical track are already predetermined. Output of the pieces from the bowl may be by continuous or timed flows. If necessary, the bowls can be internally coated to meet noise limits set by law. Rotation direction can be clockwise and counterclockwise."
