After a support structure () has been circumferentially positioned around an annular component () of a tyre (), gripping elements () carried by the support structure () and circumferentially distributed around a central axis (X) are radially approached to the annular component () bringing into contact therewith a plurality of feeler pins (), slidably carried by each of said gripping elements (). Once contact is made, the radially approaching of the gripping elements () to the annular component () continues by sliding the gripping elements themselves along the feeler pins (). All the feeler pins () can therefore come into contact with the annular component (), copying the shape of the outer surface. The feeler pins () are then locked with respect to the gripping elements () in order to allow the removal of a support drum () from the annular component () and support the latter in the absence of normal stresses.

Gripping method and apparatus for annular components of tyres for vehicle wheels

Method and plant for producing tyres for vehicle wheels in which: each vulcanizer () of a plurality of vulcanizers () is associated with a respective pick-up logic of green tyres from at least one storage area () of green tyres; upon each request to vulcanize a green tyre in a vulcanizer () of the plurality of vulcanizers (), the pick-up logic associated with said vulcanizer () is applied to select and pick up a green tyre from the storage area (); the respective pick-up logic associated with each vulcanizer () comprises a first pick-up rule of green tyres from the storage area () and, for at least one of the plurality of vulcanizers (), the first pick-up rule is changed into at least one second pick-up rule at least once during the production in the plant () of at least one lot of tyres.
