Claims19
A vibratory packing plank for a road finisher, having a vibration unit, which comprises a vibration element exhibiting a large-area base plate and first coupling means coupled to a vibration drive, for vibrating the vibration element;
- a guide plate positioned obliquely towards the base plate;
- a vibration strip disposed between the guide plate and the base plate of the vibration unit;
- and second coupling means coupled to the vibration drive, for vibrating the vibration strip, the vibration strip being provided with a run-in slope, whereby the vibration element and the vibration strip can move independently of each other.
The vibratory packing plank as claimed in 1, wherein the vibration strip has a run-in slope that essentially exhibits the same angle to the horizontal as the guide plate.
