Abstract
A method of wrapping cylindrical bales of crop material with sheet material, such as net or plastic film, includes gripping a tail of the sheet material in a dispensing mechanism during formation of a cylindrical bale in a bale forming chamber of an agricultural baler. After the bale is completed, the dispensing mechanism is moved from a retracted position to a dispensing position and the tail of the sheet material is inserted into the bale forming chamber of the baler. The sheet material is wrapped circumferentially around the bale while it is disposed in the bale forming chamber, and the dispensing mechanism is returned to the retracted position after one or more layers of the sheet material have been wrapped around the bale. When the dispensing mechanism has returned to the retracted position, the sheet material is cut by a cutting mechanism.
