ABSTRACT:
A device for controlling at least one twine guide arm 23, 24 for tying cylindrical bales in a pickup baler. The twine guide arm 23, 24 is adapted to pivot under the action of a control cable 25 close to the bale resting on the driving roller 14, while a tension arm 18 acting on shaping belts 12, 13 rests on the bale. At the end of the bale forming process, the distance between the tension arm 18 and the driving roller controls elements 33, 38 for moving the guide arm or arms 23, 24 toward a starting position corresponding to the beginning of the tying. The portion of the twine which is wound around the bale is then caught during the rotation of the bale for constituting the control parameter for controlling a cam engaging mechanism 40 adapted to engage the guide arm actuating elements 33, 38 during the tying process.
