To provide an apparatus and the like for molding a tire component for suppressing occurrence of inconvenience such as breaking of a strip, discharge of excess rubber and the like in a non-stationary state wherein a rolling speed of a rotator, a strip supply speed of a strip supply means and a rolling speed of a roll are difficult to be stabilized.

The apparatus comprises a rotator 2, a strip supply means 3, a pair of rolls 4a, 4b and a speed controlling means 5. The speed control means 5 calculates changes of respective speeds V1-V3 with time when the strip 6 is appropriately stuck in a time of sticking the strip wherein the rolling speed V1 of the rotator 2, a strip supply speed V2 of the strip supply means 3 and the rolling speed V3 of the rolls 4a, 4b are in a non-stationary state. While the strip 6 is stuck under the non-stationary state, the rolling speed V1 of the rotator 2, the strip supply speed V2 of the strip supply means 3 and the rolling speed V3 of the rolls 4a, 4b are controlled based on the calculated results.
