Abstract
An agricultural baler for making cylindrical bales of crop material has a sledge assembly moveable between bale starting and full bale positions. The sledge assembly includes a plurality of rollers which cooperate with an apron to define a bale forming chamber. A mechanism is linked directly to and moves with the sledge assembly for dispensing sheet material into the bale forming chamber where it is wrapped around a cylindrical bale of crop material. A simple assembly operated by an actuator piston that moves with the sledge rollers is used to initially feed the wrap material between the sledge rollers and the crop material and then to withdraw the dispenser when the bale is wrapped while simultaneously cutting the wrap material from its feed roll.
