Abstract

A bale press includes a pressing channel in which a piston is displaceable for forming a bale from crop material supplied to the pressing channel. The bale press includes a yarn supply and a knotter device arranged at a side of the pressing channel. The knotter device has a first holder for releasably holding an end portion of a yarn, a yarn deflecting member and a knotter beak. The yarn extends between the first holder and the yarn supply across the deflecting member and a side of the bale facing away from the piston. The knotter beak ties a knot in a first stretch of the yarn extending between the first holder and the deflecting member. A second holder holds the yarn at the deflecting member in an initial phase of bale formation.
