Abstract: A method for transferring unwinders (36) using a transfer facility (38) comprising a control unit (39) for controlling the unwinders, and at least one autonomous mobile platform (40) is disclosed. The facility comprises measurement means for measuring the quantity of product wound on reels (22) supported by the unwinders and communication means. The method comprises the following successive operations: measuring the quantity of product wound on the reels and communicating the measured data to the control unit; on the basis of the measured data, determining the moment at which to transmit a removal or supply mission instruction to a mobile platform; transmitting to a mobile platform at the previously-determined moment, a mission instruction to remove or to supply a unwinder; and moving the mobile platform in such a way that it becomes positioned under a unwinder.

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.

Abstract: Technique to increase the endurance of tires comprising two crossed working layers (41, 42), comprising mutually parallel reinforcing elements (411, 421) forming, with the circumferential direction (XX?) of the tire, an angle at least equal to 20° and at most equal to 50°, the reinforcing elements being made up of individual metal threads or monofilaments having a cross section at least equal to 0.20 mm and at most equal to 0.6 mm. The end of the monofilaments comprises flats such that they reduce the shear forces in the rubber compounds of the tire under compressive loading.

Abstract: Reinforcing ply (13, 14, 15) designed to produce a tire (1) formed of an assembly of threads, mostly coated with a poorly electrically conducting rubber compound (130, 140, 150), parallel with each other and making a given angle with the longitudinal direction of said ply. The ply includes through-threads (131, 141, 151) coated with one or more layers of rubber compounds, of which the outer layer is formed of an electrically conducting rubber compound. The through-threads are inserted between the threads coated with the poorly electrically conducting rubber compound (130, 140, 150) at a pitch and in a given arrangement in such a way as to form one or more electrically conducting pathways between the upper part and the lower part of the ply.
