Process and apparatus for manufacturing tyres for vehicle wheels

An apparatus for building at least one reinforcement structure on a tyre component formed on a forming support, comprising:

• a device for feeding a reinforced continuous band-like element along a feeding direction;
• a cutting group of the reinforced continuous band-like element to form at least one first reinforcement element and at least one second reinforcement element having a first cutting length and at least one second cutting length that is different from said first cutting length, respectively;
• at least one moving and depositing device for moving said at least one first reinforcement element and at least one second reinforcement element close to the forming support and depositing said at least one first reinforcement element and at least one second reinforcement element on respective deposition areas defined on respective tyre components;
• and
• a device for controlling the translation of said cutting group along said feeding direction between a first operative position defined on a basis of said first cutting length and a second operative position defined on a basis of said at least one second cutting length.
