Abstract

A twine knotter (10) for forming two knots (16, 33) in a pair of twine strands comprising: a drive pulley (20), a bill hook (9) rotatably driven by the drive pulley (20) about a knotter axis (K) to form two successive knots (16, 33) in the pair of twine strands (5, 7), a twine holding device (18) for clamping the pair of twine strands (5, 7) between a first clamping element (21) and a second clamping element (22), and a twine knife (13) for cutting the pair of twine strands (5, 7). The second clamping element is driven rotatably about a twine holder axis (G) by the drive pulley such that the rotatable second clamping element completes two rotations for one rotation of the drive pulley, and the twine holder axis (G) and the knotter axis (K) enclose an angle of less than 45° with one another.
