1. A machine for the manufacture of bags, comprising at least one support element formed by a rotating shaft suitable for the detachable coupling of a winding core of a portable storage of a consumable material in the form of a roll from which the bags are made and mechanical means comprising a transmitting and receiving antenna arranged to transmit and receive at a working frequency for making bags from the consumable material, the machine provided with remote reading means for reading information stored in a radiofrequency tag included in the portable storage when the portable storage is coupled in the at least one support element; and with a control unit connected to the reading means which contains means for obtaining information from the radiofrequency tag, which allows identifying the type of consumable material coupled in the at least one support element, and for automatically generating a signal for controlling the mechanical means, susceptible of being used to stop the operation of the machine, depending on the information obtained by said control unit; the antenna arranged in the proximal end of the rotating shaft, fixed relative to the chassis of the machine and extending in a plane perpendicular to the rotating shaft; the antenna comprising a feed microstrip and a curved exceeded arch-shaped radiant slot located in a ground plane parallel to the microstrip and separated from the microstrip by a dielectric substrate, the curve of the slot having a substantially constant radius and curved around a central hole through which the shaft passes. 2. The machine according to claim 1, comprising several support elements, configured to receive the coupling of respective portable storages of consumable material which include respective radiofrequency tags, the remote reading means comprising a plurality of transmitting and receiving antennas each of which is assembled in the vicinity of an associated support element and is suitable for the reading of only the radiofrequency tag or tags included in the portable storage coupled to an associated one of the support elements, all the antennas being connected to the control unit, which contains or is connected to programmable means suitable for checking if the combination of the consumable materials identified matches a combination stored in a database. 3. The machine according to claim 1, wherein a length of the slot is such that when the antenna transmits and receives at the working frequency within the working bandwidth of the radiofrequency tag, the antenna essentially radiates in its second resonance mode. 4. The machine according to claim 1, wherein the working frequency of the antenna is 800 to 900 MHz. 5. The machine according to claim 1, wherein the consumable material comprises a band of tubular mesh. 6. The machine according to claim 1, wherein the slot is a closed slot. 7. The machine according to claim 1, wherein a length of the slot is between 33.3 cm and 37.5 cm. 8. A machine for the manufacture of bags, comprising: a reel of material for making the bags and comprising a radiofrequency tag;a rotating shaft on which the reel is detachably coupled;a transmitting and receiving antenna arranged to transmit and receive at a working frequency;a mechanism for making bags from the material;a remote reader that reads information stored in the radiofrequency tag when the reel is coupled to the support element; anda control unit connected to the reader and configured to obtain information from the radiofrequency tag, which allows identification by the control unit of the type of material on the reel, the control unit configure to generate a signal for controlling the mechanism based at least in part on the identification of the material;the antenna is arranged at or near a proximal end of the rotating shaft and in a plane perpendicular to the rotating shaft; the antenna comprising a feed microstrip and a curved arch-shaped radiant slot exceeding 180 degrees located in a ground plane parallel to the microstrip and separated from the microstrip by a dielectric substrate, the curve of the slot having a substantially constant radius and centered around a central hole through which the shaft passes.
