Abstract
A tire building drum can readily and reliably be adjusted in drum width, and comprises; a plurality of arcuate base segments radially expansible to collectively define a cylindrical shape; a pair of arcuate side flanges mounted on each of the arcuate base segments in opposing and spaced relation with each other to be axially slidable toward and away from each other; and an arcuate spacer section mounted on each of the arcuate base segments between the arcuate side flanges to form a cylindrical outer surface and a certain drum width of the tire building drum, the arcuate spacer section being hooked to the arcuate side flanges so as to be readily detached from and attached to the arcuate side flanges.
