Abstract
A tire building machine is disclosed that includes an adapter for use between a tire building drum and a drive mechanism that would otherwise be incompatible. In one form of the invention a tire building drum has collapsible outer drum segments that are movable between extended and retracted positions, and a rotatable shaft is connected to extend and retract the segments in response to rotation of the shaft. A drive mechanism rotates the drum and also includes an actuation mechanism that moves reciprocally between first and second displaced positions. The adapter rotates the rotatable shaft in response to reciprocal movement of the actuation mechanism and, thereby, extends and retracts the segments. In this construction, a drive mechanism that provides a reciprocating actuation movement can be combined through the adapter to drive a drum which requires a rotating actuation movement.
