<p>The monitoring system for the knotting mechanism of bales 8 of material formed on a press equipped with a knotting system comprises, on the one hand, a first finger 22 for detecting the presence of the tie 4 and coming into position above the tie at a distance from the latter, in such a way that the upper horizontal strand 4a of the tie is brought in contact with it during the formation of the bale 8 and progressively lifts it, and, on the other hand, a second finger 20a, 20b for detecting the formation of the knotting loop, which, in the active position, takes its place between the tie 4 and the bale 8 which is capable of being driven by an axle 15 perpendicular to the movement of the tie, in the retracted position, as a result of the passage of the rear vertical strand 4b of the latter, a drive member 16, 17, 18 interacting with the second finger 20a, 20b to cause it to change from its retracted position to its active position in response to the lifting of the first finger by the tie 4, and a signal transmitter 26, 27 being capable of being excited as a result of the rotation of the said axle 15.
