Abstract: The invention relates to square-meshed net, and method and machine for knotting the same. In knotting a net using upper hooks arranged in a line, warp is arranged in opposition to the upper hooks and knotted to weft by the same upper hook as that in opposition to warp, and weft is transferred in one cycle of the knotting to next upper hook in a prescribed direction and knotted to warp by the next upper hook. In knotting a net using upper hooks arranged in circular form, warp (or weft) is knotted to weft (or warp) by the same upper hook as that in opposition to warp (or weft), and weft (or warp) is transferred in one cycle of the knotting to next upper hook in a prescribed direction and knotted to warp (or weft) by the next upper hook. Warp and weft are perpendicular to each other at the unfolded state and rectangular meshes are constituted. In some case, weft is turned twice and constitutes S-shaped loop.

Abstract: A method of arranging twine around a bale of straw or hay formed by pressing in a baling machine in which twine is fed from two separate bobbins, and, while pressure on the bale is maintained, one knot is laid in both pieces of twine for tying off the bale and another knot as starting knot for a following bale. The time periods of the formation of the knots overlap. The knots formed are noose type knots. The knots are formed under substantially no tension, so that the bales can be pressed with a considerable pressure, and a resulting increased density, without affecting the process of forming the knots or the firmness and stability of formed knots.Apparatus for binding bales in a baling machine comprising means for supplying twine for each twine loop, from two separate bobbins, and first and second rotary driven knotters.

Abstract: Knotting devices for tying incrementally fed string into overhand knots comprises a pair of sturdy opposed angular bills extending uprightly as stalks from a manipulatable shank and the bills including opposed horns laterally extending from the stalks and at a transverse fixed-spacing. Once the string increment is looped around the horns, its trailward-length is resiliently grasped by a retainer means located between the horns to form a noose. Following severing of the string trailward-length, its lead-end is pulled away from the knotting device and the noose slips off the bill horns fore-ends, and finally the retainer means is released thereby resulting in the overhand knot.

Abstract: In a crop baler each compacted bale is progressively formed in the bale chamber and incrementally advanced therethrough by the successive packing of new charges of loose material into the chamber against the trailing end of the partial bale. Yieldable resistance to movement of the bale through the chamber is normally provided by a previously formed and tied bale in order that the forming bale may be packed and densified in the proper way. Each bale is bound in its compacted condition by at least one complete loop of binding material, each loop consisting of a pair of separate strands from two separate sources of supply. The two strands of each loop are circumferential complements of one another and are connected together at the two locations where they are substantially end-to-end such that each binding loop contains two knots or other types of strand connections, depending upon the nature of the binding material selected for use.
