Abstract (en)

[origin: EP0727282A1] The device has a first tube (1) for supplying the spray material and a second tube (5) for supplying compressed air. The second tube rotates about the longitudinal centre axis (7) of the first tube. The mouth (21) of the end piece (20) of the second tube is set in the flow direction after the outlet opening (22) of the first tube so that the air stream from the end piece deflects the flow of sand material emerging from the first tube. The first tube can be rotationally secured and is straight at least in its outlet end area. The angled end piece can be modular to fit detachably on the second tube. An electric or pneumatic drive unit is provided for driving the second tube.
