Knotter for a baler

A knotter is disclosed which comprises a twine holder (86), a bill hook (82), an arm (88) carrying a crotch ((92) and a cutter (94) and a twine finger (118) operated by a drive mechanism to form two knots consecutively, the first to tie together two runs of twine (64a,66a) passed around a completed bale and the second to tie together two runs of twine (64b,66b) drawn from respective supply rolls for the commencement of the next bale. The twine holder (86) serves to grip the two runs of twine drawn from the supply rolls throughout the formation of the two knots. The bill hook (22) serves to knot the runs of twine gripped by the holder (86). The cutter (94) serves to sever the runs of twine between the holder (86) and the bill hook (92). The crotch (92) pushes the twine runs off the bill hook (82) during the completion of each knot. The twine finger (118) is pivotably mounted on the opposite side of the bill hook (82) from the twine holder (86) to bring the sections of the runs of twine to be knotted within the reach of the bill hook (82). In the invention, an edge (118a) of the twine finger (118) contacting the runs of twine as the knots are pushed off the bill hook (82) by the crotch (92) comprises an obstruction (118b) to resist movement of the runs of twine in a direction transverse to their length.
