Abstract: Knotter system comprising a bill hook, a twine receiver, a cutting arm and drive components and/or means. 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 and/or means 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.
