Abstract
A knotter mechanism, primarily for use in crop baling machines, with an improved billhook and actuation means therefor is disclosed. The billhook is rotatably mounted on the knotter frame and includes a fixed jaw having an elongate shaft and a movable jaw with an integral heel portion is pivotally fixed to the fixed jaw whereby pivotable of the moveable jaw opens and closes the billhook. An actuation means in the form of a rotatable roller is mounted on the knotter frame adjacent the billhook on an axis of rotation perpendicular to the longitudinal axis of the fixed jaw shaft. As the billhook rotates, the heel portion of the moveable jaw periodically engages the roller, resulting in selective opening and closing of the billhook.
