ABSTRACT:
A device is disclosed, which is useful for subdividing and diluting an accumulated amount of pirns in bulk, which comprises a chute positioned between a pirn container, and a conveyor belt. The conveyor belt is prearranged to transfer and meter a limited number of pirns. Along the chute, at least one barrier wall is provided, which can move along a vertical, or substantially vertical, direction, and is driven by a drive source, whose enabling is commanded by a level sensor located downstream the same barrier wall. A plurality of movable barrier walls, following each other, transversely prearranged along the chute relatively to the pirn falling motion, can be used. Each barrier wall is driven by a drive source, whose enabling is commanded by a level sensor located downstream of the barrier wall.
