A method for transferring unwinders () using a transfer facility () comprising a control unit () for controlling the unwinders, and at least one autonomous mobile platform () is disclosed. The facility comprises measurement means for measuring the quantity of product wound on reels () 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.

A method for supplying green tire manufacturing machines () with elastomeric products () by means of a supply facility () comprising a loading member () and at least one transfer member () comprising an unwinder () is disclosed. The supply facility comprises a preparation station (), said preparation station comprising a manipulator arm (), and at least one motor (), 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.

A method for cleaning a vulcanization mold for tires in a curing press uses device having a collaborative mobile robot and incorporating a computer program. The robot includes an autonomous mobile platform mounted on drive wheels and having batteries supplying electricity, a dry ice dispenser, sensors for identifying the location of the mold to be cleaned, and motors ensuring its displacement between a storage location of the device and the mold to be cleaned and the displacement of an articulated mobile arm of the robot. The robot bears a nozzle for spraying dry ice from the dispenser. The device comprises means for communication with a control unit. The control unit sends a mission instruction to the device, which navigates between a storage location and the location of the mold and automatically cleans the vulcanization mold.
