Abstract
A knotter system has a bill hook, a twine receiver, a cutting arm and drive components. The twine receiver is adapted to let the twines slip during a second full rotation of the bill hook so that cutting of the twines is avoided when forming the second knot. The drive components can maintain the cutting arm in the extended position after the second rotation of the bill hook for a predetermined period which is sufficient to allow removal of the second knot from the bill hook.
