PURPOSE:To obtain a hollow container molding machine capable of altering a uniform-heating time according to the wall thickness of a preform, by providing a plurality of uniform-heating wheels for feeding a preform and selectively combining said wheels. CONSTITUTION:When a preform P has a large wall thickness, a uniform-heating wheel 5 for a short pass is preliminarily detached, the preform P is heated by a heating wheel 1 to be supplied to the blow mold 8 of a blow wheel 7 through uniform-heating wheels 3, 4. Therefore, a uniform-heating time becomes longer and the inner and outer surfaces of the preform uniformly heated even if the wall thickness is large. In the case of a thin-walled preform P, the uniform-heating wheel 5 for the short pass is preliminarily arranged and the preform P is heated by the heating wheel 1 and supplied to the mold 8 of the blow wheel 7 through uniform-heating wheels 5, 4 to shorten the uniform-heating time. |
