A doser assembly includes a hopper assembly configured to receive filler material, a vibration transmission assembly coupled to the hopper assembly, and a paddle in a hopper opening that extends through the hopper assembly. The vibration transmission assembly includes a shaft that is configured to rotate around a central rotation axis, an eccentric that is fixed to the shaft and has a center that is radially offset from the central rotation axis, a connecting rod that is pivotably connected to the center of the eccentric, and a bracket that is pivotably connected to the connecting rod. A first end of the paddle is pivotably coupled to the hopper assembly at a paddle pivot joint. The paddle is fixed to the bracket of the vibration transmission assembly separately from the hopper assembly. The vibration transmission assembly is configured to cause the paddle to reciprocatingly pivot around the paddle pivot joint.
