Abstract: A twine disk for a mechanical knotter of a hay bailer has four vee shaped V-notches each formed with a hook portion and two substantially straight edge portions to enable tying twine knots with either two strands or with four stands using the same knotter.

Abstract: A twine knotter including a bill hook for forming a knot in a twine, a twine holding device for clamping twine with a twine holder and a twine disk rotatable relative thereto, the twine disk having recesses over its circumference for receiving twine, a twine feeding device for feeding twine over the bill hook into the twine holding device, and a twine knife for cutting twine. The twine disk has at least two pairs of recesses over the circumference, each pair of recesses having a front recess in a direction of rotation of the twine disk for receiving a single twine strand or a single twine strand pair and a rear recess for receiving a further single twine strand or said single twine strand pair.

Abstract: The present invention provides a semiconductor device capable of detecting illegal data in secret data communications. A semiconductor device that transmits and receives data includes a specific bit extraction block that extracts first data from transmission data in accordance with a first rule, another specific bit extraction block that extracts second data from reception data in accordance with a second rule, and a bit pattern accumulation buffer that accumulates the first data and the second data. A scramble pattern used when scrambling the transmission data is generated by a combination of the first data and the second data accumulated in the bit pattern accumulation buffer.

Abstract: A knotter arrangement of a large square baler includes a plurality of knotter assemblies with each assembly including a knotter gear having a hub received on, and coupled for rotation with, a knotter drive shaft. Each assembly further includes a knotter frame including an upper end defined by a sleeve received on the gear hub. Mounted for rotation within four bores provided in the knotter frame are a worm gear spindle, a twine disk spindle, a billhook spindle and a knife arm shaft.

Abstract: The present invention relates to a process and device for knotting a filament on a bobbin.

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 knotter comprising a billhook operable to form a knot in flexible material such as twine and being rotatable through first and second cycles during the knot tying operation, the billhook having jaws which can be opened or closed. Means are provided which are contactable by the billhook during both the first and second cycles of rotation thereof but which are operable to maintain the billhook jaws closed during the first cycle and to open and close the billhook jaws during the second cycle. The means may be in the form of a cam and releasable locking means may be provided to lock the cam against rotation during portions of the first and second cycles of billhook rotation.

Abstract: The invention relates to knotters for tying knots and has particular, but not exclusive, application to agricultural balers. In known baler knotters, twine for tying the bales is cut by a fixed or movable knife in such a way that substantially the same portion of the knife edge is used for cutting with the result that early blunting occurs which can give rise to only partially cut twine which adversely affects the knotter. In accordance with the invention a knotter (24) comprises a twine holder (63) operable to hold, during a knot-tying operation, a primary and a secondary portion (20,43) of twine in which the knot is to be tied, and rotary knife means (130) operable to cut at least one of said twine portions at a predetermined point in the operational cycle of the knotter and as said at least one twine portion is held by the twine holder.

Abstract: A knotter apparatus is improved by providing a frame supporting first and second rotatable shafts. A plurality of flanges are mounted on the first shaft and a billhook is mounted on the second shaft. A plurality of twine holder fingers are pivotally supported by the frame and resiliently urged relative to the flanges.

Abstract: A knotter apparatus is improved by providing a frame supporting first and second rotatable shafts. A plurality of flanges are mounted on the first shaft and a billhook is angularly mounted on the second shaft. A plurality of twine holder fingers are pivotally supported by the frame and resiliently urged relative to the flanges. The second shaft is operable for intermittently driving the first shaft.

Abstract: The occurrence of misties during a knot-tying operation is substantially limited by providing a knotter apparatus including a twine holder having a plurality of spaced apart discs defining a plurality of grooves between the discs. The discs further define a plurality of adjacent sets of notches. One of the discs has a thickness substantially greater than the other discs. As a result, the length of a portion of twine looped through one set of the notches and through an adjacent set of notches, is substantially increased.

Abstract: The problem of debris fouling of knife edges causing sloppy cutting of baling twine is limited by providing a knotter apparatus including a rotating shear plate. A knife has a cutting edge in knife sharpening engagement with the plate. A groove formed between the cutting edge and the shear plate permits debris to be removed from between the knife and the plate.

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.

Abstract: An improved knotter primarily for use with a crop baling machine is disclosed. As is known in the art, a quantity of compacted crop material is encircled with a length of twine, or similar binding material, and a knot is tied in primary and secondary portions thereof to produce a discrete package of material. The improved knotter includes a rotatable twine holder for gripping the primary and secondary portions of twine and holding them in a side-by-side relationship extending along a predetermined path. A rotatable billhook is mounted adjacent the twine holder and positioned to intersect the predetermined path. Drive means interconnecting the twine holder and billhook rotate the two elements in timed relation such that during a first cycle of the billhook the twine portions are positioned thereabout, and during a second cycle of the billhook a knot is tied therein.

Abstract: An improved knot tying mechanism, primarily for use in the agricultural industry, 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 with a worm gear thereon extends through the fixed hub to properly support the billhook adjacent the twine-gripping area. Cooperating gear teeth on the twine disc are engaged by the worm gear so that rotational power applied to the billhook shaft is transmitted therethrough to provide corresponding movement of the twine disc.
