When the lateral movement device 110 reaches the second end position D, the longitudinal movement device 120 just reaches the first end position B (shown in FIG. 6 ). When the spraying is stopped, the lateral movement device 110 quickly returns from the second end position D to the second initial position C, ready to spray the second reinforcing rib 13 .
