A twine knotter ( 10 ) for bale compactors comprises a knotting frame ( 11 ) with a knotting hook ( 9 ), supported rotatably on a knotting hook shaft ( 40 ), which forms a swivel pin in the knotting frame ( 11 ); with a hook part ( 41 ), projecting laterally from the knotting hook shaft ( 40 ), which hook part has a continuous through-opening ( 52 ) with an approximately rectangular cross section, this opening extending in the plane formed by the knotting hook shaft ( 40 ) and the hook part ( 41 ), the side boundaries of the opening being formed by cheeks ( 63, 64 ). A knotting tongue ( 44 ) is supported on the knotting hook ( 9 ) with freedom to pivot around a pivot pin ( 43 ), which is perpendicular to the plane formed by the knotting hook shaft ( 40 ) and the hook part ( 41 ) and which passes transversely through cooperating bores ( 65, 66, 67 ) in the cheeks ( 63, 64 ) and the knotting tongue ( 44 ). An internal projection, which extends radially inward in front of the end surface ( 43 ') of the pivot pin ( 43 ), is provided In the cooperating bore ( 66 ) passing through the cheek ( 64 ) of the opening ( 52 ). The outer edge of the cooperating bore ( 65 ) passing through the other cheek ( 63 ) is peened over in front of the end surface ( 43 '') of the pivot pin ( 43 ) present there.
