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: A tensioning device is described for mounting between a knotter and a twine supply roll in a baler. The device comprises a spring biased tensioning arm 210 for taking up slack in the twine 216 and a clamp 220 for gripping the twine 216 at a location between the tensioning arm 210 and the supply roll. In the invention, the clamp 220 is coupled to the tensioning arm 210 in such a manner that the force applied by the clamp 220 to grip the twine 216 varies with the position of the tensioning arm 210.

Abstract: A baler is described for forming square bales made up of several separately tied slices. The baler has a bale chamber and a plurality of needles movable in unison through the bale chamber to pass respective strands of twine from one side of the bale chamber to associated knotters located on the opposite side of the bale chamber. A first set of permanently operative knotters knot strands of twine tied around individual slices on each occasion that the needles are moved through the bale chamber. A second set of knitters configured to be selectively disabled by movement of a frame carrying their twine engaging components to a position out of reach of the tip of the needles, knot the remaining strands of twine only at the end of the formation of a complete bale.
