This machine incorporates facilities, mounted on a suitably constructed baseframe (1), for simultaneous formation of "n" ties on continuously-fed products by means of devices corresponding to the number of ties to be made, the formation of ties and their placement on the products being effected to a pre-determined cycle in a sequential manner taking each tie in turn, thread feed control mechanisms (42, 40, 41, 39) (38-1, 38-2), thread tensioning devices (37a, 37b, 37c, 28, 34a, 34b, 34c), additional knot-tightening devices (46a, 47a, 48a, 46b, 47b, 48b), thread presentation devices (4, 3a, 3), particular arrangements for deflection of the thread trajectory at the knotting head (8a, 9a, 10a) (8b, 9b, 10b), (8c, 9c, 10c), features for combined and individual control of the various mechanisms for tie formations and movement of the product-handling devices, the above features and mechanisms providing fully automated fabrication of "n" ties on the abovementioned products.
