Method for manufacturing tire blanks

A method for automatically and successively laying elastomeric elements using a facility for manufacturing tire blanks, comprising:

• a drum for manufacturing tire blanks,
• at least one collaborative robotized arm equipped with at least one effector,
• a stage of laying a plurality of elastomeric elements on the drum, comprising a predetermined sequence of steps, the sequence comprising the steps of grasping and drawing each of the elastomeric elements towards the drum using said arm,
• wherein the automatic and successive laying of the elastomeric elements on the drum includes instructions which can be executed by a processor of a control unit in order to implement:
• a stage of automatic performance of a step according to said sequence;
• a stage of interruption of said sequence;
• and
• a stage of manual performance of the interrupted step or the next step according to said sequence, wherein the interruption stage comprises a sub-stage of identifying an indication that a stage of automatic performance of a step has not been successfully performed,
• wherein to implement said sub-stage, the manufacturing facility comprises first measurement means able to evaluate the state of the tire blank during production, second measurement means able to evaluate the state of the manufacturing facility, and a database containing data taken from said first and second measurement means and associated with the automatic steps previously performed and associated with the success or failure of said steps.
