  "abstract": "A method for supplying green tire manufacturing machines (14) with elastomeric products (12) by means of a supply facility (10) comprising a loading member (30) and at least one transfer member (34) comprising an unwinder (36) is disclosed. The supply facility comprises a preparation station (32), said preparation station comprising a manipulator arm (70), and at least one motor (53), the preparation station and the unwinder being distinct from the green tire manufacturing machine. The method comprises the following successive operations: loading the reel onto the unwinder; positioning the end of the product wound on the réel; arranging the end of the product in such a way that it is laid on a dispenser of the unwinder; and transferring the reel from the preparation station to the green tire manufacturing machine.",
  "claims": [
    "1. A method for supplying green tire manufacturing machines with elastomeric products by means of a supply facility, each elastomeric product being arranged on a non-stick backing, an assembly made up of the elastomeric product and the non-stick backing being wound onto a reel, the supply facility comprising a loading member and at least one transfer member comprising an unwinder, the supply facility further comprising a preparation station, the preparation station comprising a manipulator arm able to manipulate the elastomeric product and the non-stick backing and at least one motor able to drive rotation of the reel loaded onto the unwinder, and the preparation station and the unwinder being distinct from the green tire manufacturing machine, and the method comprising the following successive steps: loading the reel onto the unwinder using the loading member; positioning an end of the assembly wound on the reel using the motor of the preparation station; arranging an end of the elastomeric product and an end of the non-stick backing in such a way that the end of the elastomeric product is laid on a dispenser of the unwinder and that the end of the non-stick backing is wound onto a bobbin of the unwinder, using the manipulator arm; transferring the reel from the preparation station to the green tire manufacturing machine, using the at least one transfer member.",
    "2. The method according to claim 1, further comprising, upstream of operation of loading the reel, the following step: transferring the reel from a storage area to the preparation station using an autonomous handling apparatus belonging to the supply facility.",
    "3. The method according to claim 2, wherein the reel is in a lying-down position in the storage area.",
    "4. The method according to claim 2, wherein the loading member is arranged on the handling apparatus.",
    "5. The method according to claim 1, wherein the supply facility comprises a joining station, the joining station comprising a collaborative manipulator arm, the method further comprising, downstream of transferring the reel into the green tire manufacturing machine, the following step: joining the end of the elastomeric product to a residual end of a previous elastomeric product supplying the green tire manufacturing machine, using the manipulator arm.",
    "6. The method according to claim 5, further comprising, downstream of joining, the following successive steps: transferring the reel from the green tire manufacturing machine to the preparation station, using the transfer member; winding onto the reel the end of the elastomeric product that is presented on the dispenser of the unwinder in such a way that the end of the elastomeric product is laid down onto the non-stick backing, or winding the non-stick backing onto the reel in such a way that the non-stick backing is no longer wound onto the bobbin, using the motor of the preparation station; and unloading the reel from the unwinder using the loading member.",
    "7. The method according to claim 6, further comprising, downstream of unloading the reel, the following step: transferring the reel from the preparation station to the storage area using the handling apparatus.",
    "8. The method according to claim 1, wherein the reel is in an upright position during transfer using the transfer member.",
    "9. A facility for supplying green tire manufacturing machines with elastomeric product, the product being arranged on a non-stick backing, and an assembly made up of the elastomeric product and the non-stick backing being wound onto a reel, the facility comprising: a loading member; a preparation station; and at least one transfer member capable of transferring the reel and comprising a unwinder onto which a reel can be loaded by means of the loading member, wherein the preparation station comprises a manipulator arm able to manipulate the elastomeric product and the non-stick backing and at least one motor able to drive rotation of the reel loaded onto the unwinder, wherein the unwinder comprises a dispenser able to support an end of the elastomeric product which has been unwound from the reel and a bobbin able to wind on the non-stick backing separated from the product, and wherein the preparation station and the unwinder are distinct from the green tire manufacturing machine.",
    "10. The facility according to claim 9, further comprising a control unit, the loading member, the preparation station, and the transfer member each comprising means of communication with the control unit so as to receive mission instructions from the control unit and so as to communicate mission status information to the control unit."

  "description_excerpt": "The present invention relates to the field of the manufacture of green tyres, and more particularly to a method and to a facility for supplying green tyre manufacturing machines with elastomeric products. The elastomeric products used in the manufacture of green tyres generally come in the form of continuous plies or strips, possibly reinforced, and are laid on a non-stick backing also referred to as an interleaf. Each assembly made up of an interleaf and of a product is wound on a reel while the product is being stored and transported. The green tyre manufacturing machine generally comprises a drum, laying stations and supply stations. The elastomeric products are laid circumferentially on the drum using the laying station so as to form a green tyre. Each laying station draws an elastomeric product from a supply station. The supply station unwinds the assembly made up of the interleaf and of the product from the reel, removing the interleaf, thus supplying the green tyre manufacturing machine with product. Each supply station therefore comprises a unwinder on which a reel is loaded, the unwinder allowing the product to be unwound from the reel. However, exchanging an empty reel for a full reel entails stopping the operations of laying a product on the drum, and this reduces the productivity of the machine.\n\nA reel-change is generally performed by an operator. First of all, the unwinder belonging to the supply station rewinds the interleaf previously unwound with the product on the reel. The operator then removes the reel from the supply station of the machine and introduces a new reel thereinto.",
