  • Tire building drum including an expandable segmental cylinder assembly and a vacuum chamber
    Patent number: 4929298
    Abstract: A tire building drum (10) has a plurality of expandable axially extending, circumferentially spaced-apart segments (18) with an elastic cover sleeve (48). The radius (C) of the radially inner surface (50) of the cover sleeve (48) is greater than the radius (B) of the radially outer surface (20) of the segments (18) in the contracted condition of the drum (10) for placing the cover sleeve (48) over the segments (18) and is less than the radius (A) of the radially outer surface (20) of the segments (18) in the expanded condition of the drum (10) for gripping the segments (18) and maintaining a precise position of the cover sleeve (48). The segments have replaceable cover plates (38) of different thicknesses which are easily interchangeable to provide different drum components for different size tires.
