Abstract: A bale binding mechanism is configured to secure a strand of binding material around a bale of severed crop material. The bale binding mechanism includes a chassis, a knotter head assembly, and a captive lock. The knotter head assembly is operable to form at least one knot in the strand of binding material. The knotter head assembly includes a knotter head frame swingably mounted relative to the chassis and rotatable into and out of an operating position where the knotter head assembly can form the at least one knot. The captive lock is shiftably supported by one of the chassis and the knotter head frame. The captive lock is removably engaged with the other one of the chassis and the knotter head frame to secure the knotter head assembly in the operating position, with the captive lock being releasable to permit rotation of the knotter head assembly out of the operating position.

Abstract: A knotter system has a billhook; a twine receiver; a twine delivering system for delivering twines across the billhook to the twine receiver; a swing arm having a lower end portion with a knife blade, moveable below the billhook, a first drive to make the billhook perform at least a first and a second full rotation to move the swing arm two times from a backward to a forward position and back to form respectively a first and second consecutive knot; wherein the twine receiver comprises a rotatable twine disc and a twine holder adapted to clamp twines against the twine disc; wherein said twine disc is provided with at least a first and a second notch for receiving the twines, and a protruding ridge located after the second notch, such that the twine holder is pushed by the ridge during and/or after the formation of the second knot.

Abstract: The twine knotter (10) is designed according to the Deering high-pressure system and, as a result of a greater inclination of the knotter hook (26), has a distance (40), measured along the twine strand (25), between the mid-plane of the knotter hook (26) and the pivoting plane of the knife (20) of at least 40 mm, so that the knot ends become longer. Consequently, where thicker baler twine and correspondingly bulkier knots are concerned, the danger that the knot will come loose under tension is reduced.

Abstract: A bale twine knotter comprised of a rotatably mounted billhook for forming a loop of twine thereabout and a wiper arm with an improved adjustably mounted wiper for sliding a twine loop from the billhook while the twine end is retained in a jaw of the billhook to complete the formation of a twine knot. The adjustable mounting of the wiper permits the spacing of the wiper from the billhook to be adjusted easily and accurately and permits the wiper and wiper arm to be made of strong, rigid materials.

Abstract: A knot tying mechanism with improved operational capabilities is disclosed. A twine disc rotatably mounted about a central fixed hub is angularly arranged to position the twine-gripping area for better acceptance of twine from the needle and thereby reduce the incidence of misties due to inadequate gripping. A billhook shaft extends through the fixed hub to properly support the billhook adjacent the twine-gripping area, and to transmit rotational power from the shaft to the twine disc.
