Abstract
Apparatus for wrapping cylindrical bales of crop material with twine includes a feed roller, a knife, and a twine arm connected to an electrical actuator for dispensing twine. The electrical actuator is extendable and retractable in order to cause pivoting movement of the twine arm between a rest position, a twine dispensing position and a twine cutting position. A first link is connected between the electrical actuator and a crank lever, and a second link is connected between the crank lever and the twine arm. Extension of the electrical actuator moves the twine arm from the rest position to the dispensing position and simultaneously results in the feed roller being driven. Retraction of the electrical actuator moves the twine arm from the twine dispensing position toward the twine cutting position while the feed roller continues to be driven. When the electrical actuator is fully retracted, the twine arm is moved into the twine cutting position and the knife is actuated.
