Abstract
A bale chamber for an agricultural baler includes a plurality of rolls; a plurality of belts wrapped around the rolls; a movable serpentine arm in contact with the belts and configured to move responsively to lifting by at least one of the belts; and a plurality of tensioning arms, each of the tensioning arms being forced against a respective one of the belts and independently movable relative to the other tensioning arms. Each tensioning arm is configured to move against and reduce slack in its respective belt as the serpentine arm moves out of contact with its respective belt.

A bale chamber for an agricultural baler, comprising:
- a plurality of rolls;
- a plurality of belts wrapped around the rolls;
- a movable serpentine arm in contact with the belts and configured to move responsively to lifting of the serpentine arm by any one of the belts;
- and
- a plurality of tensioning arms, each of the tensioning arms being forced against a respective one of the belts and independently movable relative to the other tensioning arms, each tensioning arm being configured to move against and reduce slack in its respective belt as the serpentine arm moves out of contact with its respective belt, wherein the serpentine arm is configured to move rearwardly toward a direction of ejection of a bale when lifted by at least one of the belts, and wherein the tensioning arms are disposed in front of the serpentine arm at a position further from the direction of ejection of the bale than a position of the serpentine arm.
An agricultural baler, comprising:
- a chassis;
- a pickup comprising a plurality of tines and configured to pick up crop material from a field;
- and
- a bale chamber carried by the chassis and configured to receive crop material from the pickup, the bale chamber comprising:
- a plurality of rolls;
- a plurality of belts wrapped around the rolls;
- a movable serpentine arm in contact with the belts and configured to move responsively to lifting of the serpentine arm by any one of the belts;
- and
- a plurality of tensioning arms, each of the tensioning arms being forced against a respective one of the belts and independently movable relative to the other tensioning arms, each tensioning arm being configured to move against and reduce slack in its respective belt as the serpentine arm moves out of contact with its respective belt, wherein the serpentine arm is configured to move rearwardly toward a direction of ejection of a bale when lifted by at least one of the belts, and wherein the tensioning arms are disposed in front of the serpentine arm at a position further from the direction of ejection of the bale than a position of the serpentine arm.
