摘要：
A knotter system for a baler, comprising: a needle (11); a tucker arm (31); a billhook (100); a drive means adapted to make the billhook perform at least a first full rotation during the first knot forming cycle and a second full rotation during the second knot forming cycle. The drive means comprise a pinion (503) and at least a first and second gear stretch (504, 505) provided along the circumference of a disc (501). The disc is provided with a recess (550; 555) downstream of at least one of said first gear stretch (504) and said second gear stretch (505). An obstacle (560; 565) is arranged for engaging the pinion (503) when moving in the recess. The recess and obstacle are configured to rotate the pinion over a determined angle and back to move the upper lip (101) of the billhook away from the lower lip (102) and back after at least one of said first full rotation and said second full rotation.
