Abstract: Beads are transferred in the form of a flow along supply channels into first holding pockets; the beads from the holding pockets of the bead feeding unit are fed to receiving pockets of a bead transfer unit by means of movable feeding means, then in the bead transfer unit the beads are inserted into a guiding chamber formed at the intersection of a guiding groove of a first guiding plate and a guiding groove of a second guiding plate of the bead transfer unit, at least one guiding plate is rotated relative to the second guiding plate, which forces the movement of the guiding chamber so that the distance of the guiding chamber to the axis of rotation of the guiding plates changes, and the beads from the guiding chamber or the guiding channel are conveyed to a outfeeding pocket.
