1. A binding apparatus for cylindrical bale presses comprising at least one chain (16) or the like which passes over two wheels (10, 11) each provided in the vicinity of a different side of the press and which extends parallel to the aperture for the intake of the crop products into the press, an element (17) for guiding the yarn (24), which element is displaced by said chain (16) transversely with respect to the press in front of said crop product intake aperture, a pulley (20) around which the yarn (24) passes or is wound between the yarn box and the yarn guide element (17) before reaching said crop product intake aperture, so as to cause said pulley to rotate when a pulling force is applied to the yarn by the bale in the course of the binding operation, and members (20, 22, 23) for driving the chain, disposed between said pulley and said chain, characterised in that said element for guiding the yarn (24) comprises a finger (17), a hook member, a ring or an equivalent element, which is directly carried by the chain (16) or the like, that the drive members (21, 22, 23) provided between the pulley (20) and the chain (16) are so arranged as to permit displacement of the chain (16) independently of the pulley (20), outside of the binding period, and that a connecting means (12, 13) is provided between one (11) of the wheels, around which the chain (16) passes, and an element of the press which is displaced in the course of formation of the bale, to move said yarn guide element (17) into a starting position in the vicinity of one of the wheels (10, 11) before the bale binding operation. |
