Abstract: A knotter had a twine holder, a bill hook, an arm carrying a crotch and a cutter and a twine finger operated by a drive mechanism to form two knots consecutively, the first to tie together two runs of twine passed around a completed bale and the second to tie together two runs of twine drawn from respective supply rolls for the commencement of the next bale. The twine holder serves to grip the two runs of twine drawn from the supply rolls throughout the formation of the two knots. The bill hook serves to knot the runs of twine gripped by the holder. The cutter serves to sever the runs of twine between the holder and the bill hook. The crotch pushes the twine runs off the bill hook during the completion of each knot. The twine finger is pivotably mounted on the opposite side of the bill hook from the twine holder to bring the sections of the runs of twine to be knotted within the reach of the bill hook.
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 tying device for knotting together respective ends of two threads extending in opposite directions and having two tying jaws rotatable in opposite directions and disposed mutually opposing and laterally offset from one another, a cup wheel toothed at a rim thereof and meshing with drive pinions of the tying jaws, the cup wheel having entrainers disposed at varying levels for introducing and guiding the thread ends, and serving for driving the tying jaws, a longitudinally shiftable stripper for the knotted thread disposed in the center of the cup wheel, and two thread clamping devices disposed outside the cup wheel each of the thread clamping devices disposed outside the cup wheel, each of the thread clamping devices being controllable and having multiple looping clamps formed with threading contours, a device for equalizing and limiting bearing pressure at looping locations thereof, and a control device includes a pivotally mounted, controllable two-armed lever having a longer and a shorter lever arm, th
