Apparatus for the manufacture of pneumatic tires

A tire carcass building apparatus comprising:

• (i) a first rotatable turret having a plurality of first formers for the manufacture of tire carcass cylindrical inner liners thereon and which are rotatably displaceable between a number of stations;
• (ii) a third rotatable turret having a plurality of second formers for the manufacture of a tire carcass and which are rotatably displaceable between a number of stations,
• (iii) a transfer means for transport of the inner liners from one station on the first rotatable turret to a second station on the third rotatable turret, and which comprises a second rotatable turret with at least three cylindrical transfer sleeves each for supporting a respective cylindrical inner liner on its inner periphery, said transfer sleeves being rotatably displaceable between fixed positions and arranged so that one of the transfer sleeves is in alignment one with said one of the stations of the first turret, and simultaneously, another of the transfer sleeves is in alignment one with one of said stations of the third turret;
• and
• (iv) the first and second formers being mounted for movement with respect to their respective axes so as to become concentric with a transfer sleeve aligned therewith.
