- weighing elements,
- a transport belt positioned on said weighing elements and below said feed shaft, said transport belt receiving said fiber tufts from said separation unit, and
- a chute located at an end of said transport belt, said chute receiving said fiber tufts from said transport belt, wherein said fiber tufts drop freely from said transport belt at said end of said transport belt without further separation, and wherein a longitudinal axis of said separation unit is approximately parallel to a running direction of said transport belt so that said fiber tufts float over substantially an entire length of said transport belt.
