A method for controlling a braking mechanism (36, 136) for a supply roll (14) with wrapping material (12, 112) for a round baler that passes through the following phases during its operating cycle: - a first phase wherein, after detection of sufficient crop material in the baling chamber (10), wrapping material is brought up to the baling chamber and introduced into the baling chamber; - a wrapping operation; - a cutting operation; - an ejection operation; and - the subsequent phase in which new crop material is fed into the baling chamber (10), whereby the braking mechanism is operated to provide a higher braking force during the wrapping operation than during the first phase. In accordance with the method of the invention, the wrapping operation is started on detection of movement in the wrapping material. This prevents the braking mechanism from being activated prematurely and leaves sufficient time to deactivate the braking mechanism after the wrapping operation. |
