ABSTRACT:
Apparatus for forming roll bales of agricultural harvest material operating to helically tie the roll bales with twine is provided with a twine guide member moving along a front intake aperture of the baler and automatically controlled by a ratchet and pawl mechanism. The guide member is biased toward a lateral rest position by a spring. An actuating line is attached to the guide member to enable the guide member to be moved to an opposite lateral start position against the force of the spring. The actuating line is wound around a pulley of the ratchet and pawl mechanism. The ratchet and pawl mechanism includes a releasing disc which is driven by the twine itself during a tying operation and which carries a lifting cam which alternately disengages a pair of pawls of the ratchet and pawl mechanism. The guide member is first pulled by the actuating line into its start position and the spring will subsequently draw the guide member back toward its rest position with the return motion being controlled by the ratchet and pawl mechanism.
