1. A twine knotter for forming two knots in a pair of twine strands comprising:
a drive pulley driven intermittently rotatably about a drive axis,
a bill hook rotatably driven by the drive pulley about a knotter axis to form two successive knots in the pair of twine strands by two complete rotations of the bill hook in one rotation of the drive pulley,
a twine holding device for clamping the pair of twine strands between a first clamping element and a second clamping element of the twine holding device, the second clamping element being rotatably driven by the drive pulley, and
a twine knife for cutting the pair of twine strands,
wherein the rotatable second clamping element of the twine holding device is driven rotatably about a twine holder axis by the drive pulley in such a way that the rotatable second clamping element completes two rotations for one rotation of the drive pulley, and
wherein the twine holder axis and the knotter axis, viewed in the direction of the drive axis, enclose an angle of less than 45° with one another.
