ABSTRACT:
This invention relates to an apparatus for grading flowers on the basis of the thickness of the stem, wherein each flower stem is passed between a rotatable roller and a restraint. One of these two members is arranged for movement and is urged towards the other member under the influence of a force. The displacement of the rotatable roller resulting from the passage of the flower stem is a measure for the thickness of the stem. The rotatable roller is driven at a peripheral velocity which is approximately equal to the speed of the passing flowers.
