ABSTRACT:
The invention concerns a method and an apparatus for ejecting a material, in particular a straw material, having a pivot unit comprising an impeller blower, a cooperating fluid cylinder, with a control unit comprising at least one directional control valve for control of the fluid cylinder so that at least one ejection nozzle of the impeller blower can be pivoted reciprocally. The control unit further comprises a pressure control valve. An electrical control device is provided, which acts on the pressure control valve and/or the directional control valve in such a way that a piston of the fluid cylinder essentially performs a harmonic reciprocating movement.
