ABSTRACT:
Herein disclosed are pneumatic tire building method and apparatus for applying a continuous rubber strip on a tire carcass preliminarily wrapped around a tire building drum to produce a pneumatic tire having a tread rubber portion and one or more side rubber portions both of which or any one of which consists of different rubber materials. A pair of calender rollers are positioned in opposing and spaced relation with each other and each having a rotational axis parallel to that of said tire building drum, and at least one comparment plate is vertically disposed on and between said calender rollers in perpendicular relation with said rotational axes of said calender rollers and having a lower edge contoured in sliding contact with said calender rollers. At least one separator relatively movably mounted on said compartment plate and having a lower edge contoured in sliding contact with said calender rollers to separate and joint said calendered rubber materials. The separator is vertically moved to its lowest and uppermost positions so that different rubber materials partitioned on the calender rollers by the compartment plate are separately and jointingly calendered. The separated rubber material is removed while the remaining rubber material is applied on the tire carcass preliminarily wrapped around the tire building drum to build a desired contour of tread and side portions.
