ABSTRACT:
A rectangular baler has a density control for controlling the density to which crop material is compacted in a bale case by a cyclically operating plunger, and a cyclically operating tying mechanism for typing loops of binding material around successive lengths of the compacted crop material to form bales. In order for the tying mechanism to function properly the binding material must slide between a tied bale and the crop material being compacted against the tied bale. If the sliding friction is too great, the binding material breaks or is pulled free of the tying mechanism thus resulting in failure of the tying process. To reduce the sliding friction, the density to which the crop material is compacted is reduced for an interval of time following each cycle of the tying mechanism. The interval of time is controlled by the rate at which crop material enters the bale case following a cycle of the tying mechanism.
