Abstract: A tire picking system (100) performs a process for picking one or more tires stored in an unknown arrangement and for which a target location must be realized. A gripper (108) and a robot (102) including a gripping device (104) supported by a pivotable elongated arm (106), the gripping device extending from the elongated arm to a free end (104a) where the gripper is disposed, form part of the system (100). An image processing module applies data representative of the physical environment around the robot (102) to a deployed neural network in order to determine one or more parameters of a target tire (P*); the robot is set in motion based on the determined parameters of the target tire, so that the gripper can pick a target tire (P*) selected by the system (100) from among the stored tires.

The facility includes a drum for manufacturing tire blanks and at least one collaborative robotized arm equipped with at least one effector. A stage of laying an elastomeric element includes a predetermined sequence of step. The sequence comprises the steps of grasping and drawing the elastomeric element towards the drum using said arm. The automatic and successive laying of elastomeric elements includes instructions which can be executed by the processor of a control unit in order to implement. The sequence includes a stage of automatic performance of a step according to said sequence. The sequence also includes a stage of interruption of said sequence. The sequence further includes a stage of manual performance of the interrupted step or the next step according to said sequence.

Abstract: A method for detaching elastomer particles that adhere on microvalves (3) disposed on the internal surface of a vehicle tire mold (2) comprises vibrating the microvalve (3) at a constant amplitude ranging between approximately 0.05 and 0.2 mm and at a frequency ranging between 20,000 and 30,000 Hz during the detachment of the particles from the microvalve (3).

Abstract: A drum for producing a tire casing blank comprises a support and sectors forming a circumferential face of the drum. Each sector has a circumferential outer face having a contour of general trapezoidal form and is mounted so as to be movable relative to the support in a non-radial predetermined direction relative to an axis of rotation of the drum and intercepting this axis.

Abstract: Method for cleaning a vulcanization mould for tyres in a curing press, using a device (1) comprising a collaborative mobile robot (10), incorporating a computer program, said robot comprising an autonomous mobile platform (2) mounted on drive wheels and comprising batteries supplying electricity, a dry ice dispenser (6), sensors for identifying the location of the mould to be cleaned and motors ensuring its displacement between a storage location of the device and the mould to be cleaned and the displacement of an articulated mobile arm (3) of said robot, said robot bearing a nozzle (4) for spraying dry ice from said dispenser, wherein the device comprises means for communication with a control unit. According to the invention, the control unit sends a mission instruction to said device, which navigates between a storage location and the location of the mould and automatically cleans the vulcanization mould.

Abstract: A drum for building a green tire casing having: sectors that form a circumferential face of the drum, and at least one cam for controlling a radial movement of the sectors with respect to a rotation axis of the drum. The cam has two main faces and is designed such that a monotonous movement of the cam first of all causes the radial movement of some of the sectors by virtue of ramps situated on its first face without modifying a radial position of the other sectors, and then causes the radial movement of the other sectors by virtue of ramps situated on its second face, the movement of all of the sectors then being simultaneous.

Abstract: A method for manufacturing a tire involves successively performing steps that include: continuously converting a flat reinforcing strip into an undulating reinforcing strip; pressing peaks of waves of the undulating reinforcing strip one by one onto a surface of a tire blank that is driven in rotation by a drum about a drum axis; and winding the undulating reinforcing strip onto the tire blank. In the converting step, the flat reinforcing strip is converted into the undulating reinforcing strip in an immediate vicinity of the drum. The waves of the undulating reinforcing strip and movement of the peaks of the waves of the undulating reinforcing strip towards the surface of the tire blank extend in a plane substantially perpendicular to the drum axis.
