<p>1. A binding control apparatus for cylindrical or round bale presses, of the type comprising a twine guide arm (8) mounted pivotally in a position such that the free end thereof can perform a transverse sweep movement relative to the bale forming chamber of the press between a starting position towards which said arm is urged by resilient means (13) and a final position into which it is positively moved from said starting position and in which it is normally locked in the rest condition, and a pulley (23) or like member around which the binding twine (9) is wound so as to cause rotary movement of said pulley or said like member when a pulling force is applied to said twine by the bale (34) at the moment of the binding operation, means being provided to produce the displacement or said sweep movement of the twine guide arm under the action of said pulley during said binding operation, characterised in that said latter means comprise a shaft (10) whose axis is parallel to the pivot axis of the twine guide arm (8) or coincides with said pivot axis, at least one entrainment arm (16) which is carried by said shaft and driven in rotation therewith, said arm (16) being independent of the twine guide arm (8), entrainment means (26-28) provided between said pulley (23) and said shaft (10) to cause rotary movement of the shaft when the pulley is entrained under the action of the binding twine, and means (17, 18) for making a connection between said entrainment arm (16) and the twine guide arm (8) upon rotary movement of said shaft (10) in order to produce positive displacement of said twine guide arm (8) between ist starting position and its final position.</p> |
