ABSTRACT:
Bagging machines may include a packing density measurement system. The packing density measurement system includes an anchor assembly and a force measurement assembly. The anchor assembly includes at least one drag member adapted to be operatively coupled to the bagging machine and to extend rearwardly beneath at least a portion of a bag to resist forward movement of the bagging machine. The force measurement assembly is operatively coupled to the anchor assembly and is adapted to measure the anchoring force applied to the bagging machine. The anchor assembly may be adjustable, either manually or automatically, to allow control over the anchoring force.
