1. A binding control apparatus for cylindrical bale presses, of the type comprising a twine guide arm 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, and wherein the pivotal movement of the twine guide arm is produced by the pulling force applied by the demand for the binding twine which, between the twine box and the twine guide arm, is wound around a pulley or the like, the rotation of which causes said pivotal movement of the arm, characterised in that fixed on the pivotal arm (7) and in a position spaced from the pivot axis (8) thereof is a support (12) in which a vertical shaft (13) is journalled, the vertical shaft (13) carrying on the one hand the pulley (14) or the like around which the binding twine (11) is wound and, on the other hand, a toothed wheel (15) or the like which is engaged with a tooth engagement member (16) which extends transversely with respect to the press, whereby the pulling force applied to the twine by demand therefor by the bale in the binding operation causes, in known manner, rotation of the pulley (14) and, by way of the shaft (13), rotation of said toothed wheel (15) which is then displaced on said transverse tooth engagement member (16), producing the sweep movement by pivoting motion of the twine guide arm (7). |
