ROUND BALER WITH POSITION CONTROLLED TAKE-UP ROLLER, AND METHOD OF OPERATING A ROUND BALER

摘要

A round includes a housing (32) and a gate (36) rotatably attached to the housing (32) for rotation about a gate rotation axis (42), and a forming belt (64) that defines a variable sized baling chamber (54). A take-up roller (68) supports the forming belt (64). A first actuator (92) is coupled to the take-up roller (68) and is operable to automatically apply a first bias force (94) to the take-up roller (68) to urge the take-up roller (68) into a slack take-up position to reduce slack in the forming belt (64) as the gate (36) moves relative to the housing (32). A second actuator (98) is coupled to the take-up roller (68) for applying a second bias force (100) to the take-up roller (68), in opposition to the first bias force (94), to restrict movement of the take-up roller (68) into the slack take-up position to introduce slack into the forming belt (64) when the gate (36) is opened to an intermediate position.
