In a hay baler for producing rolled bales of the type having a shaping chamber in which the hay introduced in the form of a sheet is wound on itself around a horizontal axis (XX'), a tying mechanism has two distributors for ties which are mounted to swivel under the action of a control means to perform a reciprocating movement along the shaping chamber from a rest position near one end of the chamber to an end-of-tying position near the opposite end of the chamber. The distributors are mounted to rotate around an axis (Y) fixed to one of the side walls of the baler while the control means is fixed to the other side wall. An actuator with a reciprocating movement controlled by the control means first successively drives the distributors from the rest position to the end-of-tying position in the vicinity of which a severing means interrupts the ties, then returns the distributors to the rest position.
